btrfs-progs: Documentaion: rename to .asciidoc

A few minor benefits:

* editors set highliting according to the extensions
* web access to the git repository (github) renders the .asciidoc
  files:
  * we can link to them from the wiki
  * the files are editable via browser and such editations can be
    submitted for merge easily

+=========================

+NAME
+----
+btrfs-inspect-internal - resolve different btrfs items for debug purpose
+
+SYNOPSIS
+--------
+*btrfs inspect-internal* <subcommand> <args>
+
+DESCRIPTION
+-----------
+*btrfs inspect-internal* is used to resolve different items for debug purpose.
+
+SUBCOMMAND
+----------
+*inode-resolve* [-v] <inode> <path>::
+Resolves an <inode> in subvolume <path> to all filesystem paths.
++
+`Options`
++
+-v::::
+verbose mode. print count of returned paths and ioctl() return value
+
+*logical-resolve* [-Pv] [-s <bufsize>] <logical> <path>::
+Resolves a <logical> address in the filesystem mounted at <path> to all inodes.
++
+By default, each inode is then resolved to a file system path (similar to the
+inode-resolve subcommand).
++
+`Options`
++
+-P::::
+skip the path resolving and print the inodes instead
+-v::::
+verbose mode. print count of returned paths and all ioctl() return values
+-s <bufsize>::::
+set inode container's size.
++
+This is used to increase inode container's size in case it is
+not enough to read all the resolved results. The max value one can set is 64k.
+
+*rootid* <path>::
+For a given file or directory, return the containing tree root id. For a
+subvolume return it's own tree id.
++
+The result is undefined for the so-called empty subvolumes (identified by inode number 2).
+
+*subvolid-resolve* <subvolid> <path>::
+Get file system paths for the given subvolume ID.
+
+EXIT STATUS
+-----------
+*btrfs inspect-internal* returns a zero exit status if it succeeds. Non zero is
+returned in case of failure.
+
+AVAILABILITY
+------------
+*btrfs* is part of btrfs-progs.
+Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for
+further details.
