btrfs-show-super has own implementation to read the sys array and it
lacks all the sanity checks.
Copy and adapt the improved implementation from btrfs_read_sys_array.
This will fix crashes on a fuzzed/corrupted images. It's duplicating
code but at the moment looks easier than refactoring and restructuring
btrfs_read_sys_array that now almost matches the kernel code, which we
want in the long term.

We can handle the special case of num_stripes == 0 directly inside
btrfs_read_sys_array. The BUG_ON in btrfs_chunk_item_size is there to
catch other unhandled cases where we fail to validate external data,
like in btrfs-show-super.

Port of kernel commit 1ffb22cf8c322bbfea6b35fe23d025841b49fede

There are some sanity checks missing on both sides, kernel/userspace.
Preparation to port the missing changes.
Sync code with parent of kernel commit
1ffb22cf8c322bbfea6b35fe23d025841b49fede ("btrfs: cleanup, rename a few
variables in btrfs_read_sys_array")
This effectively reverts progs commit
be96777126d283773e4397278a5662d90676ab88 ("btrfs-progs: Cleanup unneeded
extra variant in btrfs_read_sys_array") so we can apply more of the
kernel patches.

The conversion to autotools changed the default prefix to /usr. There's
no reason to diverge. Distributions builds set prefix the /usr path and
local builds are supposed to go to /usr/local .

Current code don't support DUP profile on single device, except it
is in mixed mode, because of following reasons:
1: Some SSD do deduplication internally, so the duplication on
the filesystem side has no effect.
2: On a physical device, if the entire disk broken, --data DUP does not
help.
3: Half performance compared to single profile.
4: We have a workaround: create multi-partition on a single device,
and btffs will treat them as multi device.
Instead of refusing --data DUP, we give the user a choice and print
a wrning.
Test:
1: Tested by xfstests
Run with modified xfstests, I add test items of -d dup in single
device into btrfs/* and common/rc, run tests of btrfs/*,
with all mount option, no regression diffed with v4.3.
2: Tested by btrfs-progs
Checked following commands in "-m dup -d dup" fs with memleck
checking, all passed:

In process_extent_item(), it gives 'metadata' initial value 0, but for
non-skinny-metadata case, metadata extent can't be judged just from key
type and it forgot that case.
This causes a lot of false alert in non-skinny-metadata filesystem.
Fix it by set correct metadata value before calling add_extent_rec().

If sectorsize is not BTRFS_SUPER_INFO_SIZE (4k), the superblock checksum
is wrong and mkfs fails. This has been reported on ppc64 where we pick
sectorisize from page size (64k). This has been broken since ages
(2008) and discovered by the recently added superblock checks.

When using partitions on a loop device, the device's name can be
e.g. /dev/loop0p1 or similar, and no relevant entry exists in the /sys
filesystem, so the current resolve_loop_device function fails.
Instead of using string functions to extract the device name and reading
this file, this patch uses the loop device API through ioctl to get the
correct backing file.

in system chunk, which should be very easy to add, just iterate in

A test for "btrfs-progs: mkfs: increase buffer size in is_ssd". Create a
device with a long name through loop device wrapped to a device mapper
linear device, switch it to the "ssd" mode status.

In current versions of util-linux the buffer passed to blkid_devno_to_wholedisk
has to be sufficiently large to not only hold the device name but the complete
target of the /sys/dev/block/<maj:min> symlink. This was changed only recently
in 4419ffb9eff5801fdbd385a4a6199b3877f802ad.
The small buffer size currently can lead to failure of is_ssd due to truncated
device names:
readlink("/sys/dev/block/254:7", "../../devices/virtual/block/dm-", 31) = 31
open("/sys/block/dm-/queue/rotational", O_RDONLY) = -1 ENOENT (No such file or directory)

Device deletion procedures ensures the device is a block device.
This patch introduces 'missing' as keyword again, correctly
passing it on to the kernel instead of complaining about
'missing' not being a block device.
