[PATCH 1/2 V2] btrfs, a new tool to manage a btrfs filesystem; source code

[Goffredo Baroncelli <kreijack@gmail.com>]

[-- Attachment #1: Type: Text/Plain, Size: 19118 bytes --]

This is the source code of btrfs.c.
The main changes from my previous patch are:
- Rearranged the short command in order to avoid conflicts
- Renamed the 'create' verb is 'subvolume'
- Rearranged the parsing code, which now is integrated in the help in order to avoid mismatch
