Remove Yotta support from the docs, tests and build scripts

Yotta is no longer supported by Mbed TLS, so has been removed. Specifically, the following changes have been made: * references to yotta have been removed from the main readme and build instructions * the yotta module directory and build script has been removed * yotta has been removed from test scripts such as all.sh and check-names.sh * yotta has been removed from other files that that referenced it such as the doxyfile and the bn_mul.h header * yotta specific configurations and references have been removed from config.h

+There are currently three active build systems used within Mbed TLS releases:
 
--   yotta
 -   GNU Make
 -   CMake
 -   Microsoft Visual Studio (Microsoft Visual Studio 2010 or later)
 
 The main systems used for development are CMake and GNU Make. Those systems are always complete and up-to-date. The others should reflect all changes present in the CMake and Make build system, although features may not be ported there automatically.
 
-Yotta, as a build system, is slightly different from the other build systems:
-
--   it provides a minimalistic configuration file by default
--   depending on the yotta target, features of Mbed OS may be used in examples and tests
-
 The Make and CMake build systems create three libraries: libmbedcrypto, libmbedx509, and libmbedtls. Note that libmbedtls depends on libmbedx509 and libmbedcrypto, and libmbedx509 depends on libmbedcrypto. As a result, some linkers will expect flags to be in a specific order, for example the GNU linker wants `-lmbedtls -lmbedx509 -lmbedcrypto`. Also, when loading shared libraries using dlopen(), you'll need to load libmbedcrypto first, then libmbedx509, before you can load libmbedtls.
 
-### Yotta
-
-[yotta](http://yottabuild.org) is a package manager and build system developed by Mbed, and is the build system of Mbed OS 16.03. To install it on your platform, please follow the yotta [installation instructions](http://docs.yottabuild.org/#installing).
-
-Once yotta is installed, you can use it to download the latest version of Mbed TLS from the yotta registry with:
-
-    yotta install mbedtls
-
-and build it with:
-
-    yotta build
-
-If, on the other hand, you already have a copy of Mbed TLS from a source other than the yotta registry, for example from cloning our GitHub repository, or from downloading a tarball of the standalone edition, then you'll first need to generate the yotta module by running:
-
-    yotta/create-module.sh
-
-This should be executed from the root Mbed TLS project directory. This will create the yotta module in the `yotta/module` directory within it. You can then change to that directory and build as usual:
-
-    cd yotta/module
-    yotta build
-
-In any case, you'll probably want to set the yotta target before building unless it has already been set globally. For more information on using yotta, please consult the [yotta documentation](http://docs.yottabuild.org/).
-
-For more details on the yotta/Mbed OS edition of Mbed TLS, including example programs, please consult the [Readme at the root of the yotta module](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/README.md).
-
 ### Make
 
 We require GNU Make. To build the library and the sample programs, GNU Make and a C compiler are sufficient. Some of the more advanced build targets require some Unix/Linux tools.

 Setting the variable `SHARED` in your environment will build shared libraries in addition to the static libraries. Setting `DEBUG` gives you a debug build. You can override `CFLAGS` and `LDFLAGS` by setting them in your environment or on the make command line; compiler warning options may be overridden separately using `WARNING_CFLAGS`. Some directory-specific options (for example, `-I` directives) are still preserved.
 
-Please note that setting `CFLAGS` overrides its default value of `-O2` and setting `WARNING_CFLAGS` overrides its default value (starting with `-Wall -W`), so it you just want to add some warning options to the default ones, you can do so by setting `CFLAGS=-O2 -Werror` for example. Setting `WARNING_CFLAGS` is useful when you want to get rid of its default content (for example because your compiler doesn't accept `-Wall` as an option).

-# mbed TLS
-
-mbed TLS makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their embedded products, with a minimal code footprint. It offers an SSL library with an intuitive API and readable source code.
-
-**Note:** The current release is beta, and implements no secure source of random numbers, weakening its security.
-
-Currently the only supported yotta targets are:
-- `frdm-k64f-gcc`
-- `frdm-k64f-armcc`
-- `x86-linux-native`
-- `x86-osx-native`
-
-## Sample programs
-
-This release includes the following examples:
-
-1. [**Self test:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-selftest) Tests different basic functions in the mbed TLS library.
-
-2. [**Benchmark:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-benchmark) Measures the time taken to perform basic cryptographic functions used in the library.
-
-3. [**Hashing:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-hashing) Demonstrates the various APIs for computing hashes of data (also known as message digests) with SHA-256.
-
-4. [**Authenticated encryption:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-authcrypt) Demonstrates usage of the Cipher API for encrypting and authenticating data with AES-CCM.
-
-These examples are integrated as yotta tests, so that they are built automatically when you build mbed TLS. Each of them comes with complete usage instructions as a Readme file in the repository.
-
-## Performing TLS and DTLS connections
-
-A high-level API for performing TLS and DTLS connections with mbed TLS in mbed OS is provided in a separate yotta module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). We recommend this API for TLS and DTLS connections. It is very similar to the API provided by the [sockets](https://github.com/ARMmbed/sockets) module for unencrypted TCP and UDP connections.
-
-The `mbed-tls-sockets` module includes a complete [example TLS client](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/main.cpp) with [usage instructions](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/README.md).
-
-## Configuring mbed TLS features
-
-mbed TLS makes it easy to disable any feature during compilation, if that feature isn't required for a particular project. The default configuration enables all modern and widely-used features, which should meet the needs of new projects, and disables all features that are older or less common, to minimize the code footprint.
-
-The list of available compilation flags is available in the fully documented [config.h file](https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h).
-
-If you need to adjust those flags, you can provide your own configuration-adjustment file with suitable `#define` and `#undef` statements. These will be included between the default definitions and the sanity checks. Your configuration file should be in your application's include directory, and can be named freely; you just need to let mbed TLS know the file's name. To do that, use yotta's [configuration system](http://docs.yottabuild.org/reference/config.html). The file's name should be in your `config.json` file, under mbedtls, as the key `user-config-file`.
-
-For example, in an application called `myapp`, if you want to enable the EC J-PAKE key exchange and disable the CBC cipher mode, you can create a file named  `mbedtls-config-changes.h` in the `myapp` directory containing the following lines:
-
-    #define MBEDTLS_ECJPAKE_C
-    #define MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED
-
-    #undef MBEDTLS_CIPHER_MODE_CBC
-
-And then create a file named `config.json` at the root of your application with the following contents:
-
-    {
-       "mbedtls": {
-          "user-config-file": "\"myapp/mbedtls-config-changes.h\""
-       }
-    }
-
-Please note: you need to provide the exact name that will be used in the `#include` directive, including the `<>` or quotes around the name.
-
-## Getting mbed TLS from GitHub
-
-Like most components of mbed OS, mbed TLS is developed in the open and its source can be found on GitHub: [ARMmbed/mbedtls](https://github.com/ARMmbed/mbedtls). Unlike most other mbed OS components, however, you cannot just clone the repository and run `yotta build` from its root. This is because mbed TLS also exists as an independent component, so its repository includes things that are not relevant for mbed OS, as well as other build systems.
-
-The way to use mbed TLS from a clone of the GitHub repository is to run the following commands from the root of a checkout:
-
-    yotta/create-module.sh
-    cd yotta/module
-
-You can then run any yotta command you would normally run, such as `yotta build` or `yotta link`.
-
-## Differences between the standalone and mbed OS editions
-
-While the two editions share the same code base, there are still a number of differences, mainly in configuration and integration. You should keep in mind those differences when reading some articles in our [knowledge base](https://tls.mbed.org/kb), as currently all the articles are about the standalone edition.
-
-* The mbed OS edition has a smaller set of features enabled by default in `config.h`, in order to reduce footprint. While the default configuration of the standalone edition puts more emphasize on maintaining interoperability with old peers, the mbed OS edition only enables the most modern ciphers and the latest version of (D)TLS.
-
-* The following components of mbed TLS are disabled in the mbed OS edition: `net_sockets.c` and `timing.c`. This is because mbed OS include their equivalents.
-
-* The mbed OS edition comes with a fully integrated API for (D)TLS connections in a companion module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). See "Performing TLS and DTLS connections" above.
-
-## Other resources
-
-The [mbed TLS website](https://tls.mbed.org) contains many other useful
-resources for the developer, such as [developer
-documentation](https://tls.mbed.org/dev-corner), [knowledgebase
-articles](https://tls.mbed.org/kb), and a [support forum](https://tls.mbed.org/discussions).

-## Contributing
-
-We gratefully accept bug reports and contributions from the community. There are some requirements we need to fulfill in order to be able to integrate contributions:
-
-* Simple bug fixes to existing code do not contain copyright themselves and we can integrate without issue. The same is true of trivial contributions.

-# Authenticated Encryption Example
-
-This application performs authenticated encryption and authenticated decryption of a buffer. It serves as a tutorial for the basic authenticated encryption functions of mbed TLS.
-
-## Pre-requisites
-
-To build and run this example you must have:
-
-* A computer with the following software installed:
-  * [CMake](http://www.cmake.org/download/).
-  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
-  * [Python](https://www.python.org/downloads/).
-  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
-  * A serial terminal emulator (Like screen, pySerial and cu).
-* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
-* A micro-USB cable.
-* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
-
-## Getting started
-
-1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
-
-2. Navigate to the mbedtls directory supplied with your release and open a terminal.
-
-3. Set the yotta target:
-
-    ```
-    yotta target frdm-k64f-gcc
-    ```
-
-4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
-
-    ```
-    $ yotta build
-    ```
-
-5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-authcrypt.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
-
-6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
-
-   Use the following settings:
-
-    * 115200 baud (not 9600).
-    * 8N1.
-    * No flow control.
-
-7. Press the Reset button on the board.
-
-8. The output in the terminal window should look like:
-
-    ```
-    {{timeout;10}}
-    {{host_test_name;default}}
-    {{description;mbed TLS example authcrypt}}
-    {{test_id;MBEDTLS_EX_AUTHCRYPT}}
-    {{start}}
-
-
-    plaintext message: 536f6d65207468696e67732061726520626574746572206c65667420756e7265616400
-    ciphertext: c57f7afb94f14c7977d785d08682a2596bd62ee9dcf216b8cccd997afee9b402f5de1739e8e6467aa363749ef39392e5c66622b01c7203ec0a3d14
-    decrypted: 536f6d65207468696e67732061726520626574746572206c65667420756e7265616400
-
-    DONE
-    {{success}}
-    {{end}}
-    ```
-
-The actual output for the ciphertext line will vary on each run because of the use of a random nonce in the encryption process.

-Any performance data generated by this example application are indicative only of the performance of the mbed TLS module on the platform it's executed on.
-
-Differences in the integration of mbed TLS into the platform, such as whether all available hardware accelerators have been used or not, can lead to significant differences in performance, and so results from the program are not intended to be used to meaningfully compare platforms.
-
-The figures may also slightly change from execution to execution due to variations in the timing functions.

-# SHA-256 Hash Example
-
-This application performs hashing of a buffer with SHA-256 using various APIs. It serves as a tutorial for the basic hashing APIs of mbed TLS.
-
-## Pre-requisites
-
-To build and run this example you must have:
-
-* A computer with the following software installed:
-  * [CMake](http://www.cmake.org/download/).
-  * [yotta](https://github.com/ARMmbed/yotta). Please note that **yotta has its own set of dependencies**, listed in the [installation instructions](http://armmbed.github.io/yotta/#installing-on-windows).
-  * [Python](https://www.python.org/downloads/).
-  * [The ARM GCC toolchain](https://launchpad.net/gcc-arm-embedded).
-  * A serial terminal emulator (Like screen, pySerial and cu).
-* An [FRDM-K64F](http://developer.mbed.org/platforms/FRDM-K64F/) development board, or another board supported by mbed OS (in which case you'll have to substitute frdm-k64f-gcc with the appropriate target in the instructions below).
-* A micro-USB cable.
-* If your OS is Windows, please follow the installation instructions [for the serial port driver](https://developer.mbed.org/handbook/Windows-serial-configuration).
-
-## Getting started
-
-1. Connect the FRDM-K64F to the computer with the micro-USB cable, being careful to use the "OpenSDA" connector on the target board.
-
-2. Navigate to the mbedtls directory supplied with your release and open a terminal.
-
-3. Set the yotta target:
-
-    ```
-    yotta target frdm-k64f-gcc
-    ```
-
-4. Build mbedtls and the examples. This may take a long time if this is your first compilation:
-
-    ```
-    $ yotta build
-    ```
-
-5. Copy `build/frdm-k64f-gcc/test/mbedtls-test-example-hashing.bin` to your mbed board and wait until the LED next to the USB port stops blinking.
-
-6. Start the serial terminal emulator and connect to the virtual serial port presented by FRDM-K64F. 
-
-   Use the following settings:
-
-    * 115200 baud (not 9600).
-    * 8N1.
-    * No flow control.
-
-7. Press the Reset button on the board.
-
-8. The output in the terminal window should look like:
-
-    ```
-    {{timeout;10}}
-    {{host_test_name;default}}
