btrfs-subvol find-new <subvol> <id> will search through a given subvol
and print out all the files with extents newer than a given id.
Care must be taken to make sure any pending delalloc is on disk before
running this because that won't show up in the output.
This goes along with the new space info ioctl. This will spit out the space
info all nice and pretty with the type, it's flags (DUP, RAID) and how much
space is in that group and how much is in use.

This commit introduces a new command called 'btrfs' for managing
a btrfs filesystem. 'btrfs' handles:
- snapshot/subvolume creation
- adding/removal of volume (ie: disk)
- defragment of a tree
- scan of a device searching a btrfs filesystem
- re-balancing of the chunk on the disks
- listing subvolumes and snapshots
This has also been updated to include the new defrag range ioctl.
