Which is the aim of these commands ? It seems more a "debug" utilities
than a standard command. If so, these commands may be put under a new
group called "debug" or "test" or whichever we decided to use. But,
please, highlight the fact that these commands aren't for a general use.
I suggest to use
btrfs debug resolve ...
Or better
btrfs inspect resolve ...

Please update the man pages at the same time of the code. Develop the
man page coupled with the code may help to design a "good interface"
(from an user point of view) and to explain better the aim of the new
command.
