Since restore has the ability to open really really screwed up file systems, add
a list roots option to it so we can still get the contents of the tree root on a
horribly broken fs. Thanks,

search_dir() recurses down the btrfs tree, and used to take the output
path for every item (i.e. in the running system, output root directory
concatenated with btrfs-local pathname) passed as the only path
parameter. Moving the output root directory to a separate parameter
and passing the btrfs-local pathname for each file and directory
separately allows easy filtering based on the btrfs-local pathname.

If we hit a bad disk and the read doesn't work, try other mirrors in case we
have other disks with good copies. Thanks,

This will make the restore program fall back on other mirrors if it fails to
decompress an extent for whatever reason. Thanks,

If the normal fs tree is hosed and the user has multiple subvolumes it's handy
to be able to specify just one of the subvolumes to restore. It's also handy if
a user only wants to restore say /home instead of his entire disk. Thanks,

Add 'btrfs restore' command which previously existed as a separate
utility btrfs-restore.
