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
