Copy the functionality of standalone btrfs-zero-log to the main tool.
Delete man page for btrfs-zero-log and copy the relevant parts into
btrfs-rescue(8). The standalone utility will be removed later.

A few minor benefits:
* editors set highliting according to the extensions
* web access to the git repository (github) renders the .asciidoc

* we can link to them from the wiki
* the files are editable via browser and such editations can be
submitted for merge easily
