This patch forces btrfs receive to issue chroot before
parsing the btrfs stream using command-line flag -C
to confine the process and minimize damage that could
be done via malicious btrfs stream.

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

Although btrfs-convert can rollback converted btrfs, it still has some
limitation to ensure rollback.
Add a warning on the limitations.
Also add a note for users who decides to go on with btrfs and don't need
the rollback ability.

Agreed by several people, showing progress by default makes sense as
conversion is a one-time and long running action.

containing a valid btrfs filesystem.
A valid filesystem is assumed if a btrfs superblock is found
which contains a correct checksum. Devices which are currently

Fixes various formatting issues:
Fixes quoting issues in various manpages. Before/After excerpts for
mkfs.btrfs(8), btrfs-qgroup(8):
mkfs.btrfs [-A|--alloc-start '<alloc-start>']
mkfs.btrfs [-A|--alloc-start <alloc-start>]
id 0/<subvolume id>''
id 0/<subvolume id>
If multiple '<attr>'s is given, use comma to separate.
If multiple <attr>s is given, use comma to separate.
The one that is most apparent is the removal of text in
btrfs-subvolume(8) and others. Before/After:
list [options] [-G <value>] [-C <value>] [--sort=rootid,gen,ogen,path] <path>
list [options] [-G [+|-]<value>] [-C [+|-]<value>] [--sort=rootid,gen,ogen,path] <path>
create [-i <qgroupid>] <name>
create [-i <qgroupid>] [<dest>]<name>
This happens because `<foo>` was replaced by `'<foo>'` in the sed
expression, which is then treated as a constrained quote. As a result,
the `[...]` before the string gets interpreted as "quoted text
attributes".
In this patch, the sed expression is dropped and asciidoc is configured
to recognize `<...>` as a unconstrained quoted string (such that
`<attr>s` is correctly emphasized) and to avoid adding quotes in
contexts where it is not needed.
A remaining problem is that some texts (the one between brackets) do not
add the emphasis for `<...>`. While this could be solved by replacing
`[` and `]` with `[` and `]` using sed, it introduces formatting
problems in btrfs-zero-log(8) because the context is ignored.
