Calvin Walton 901314f070 Fix misleading error message in btrfsctl 
This updates Peter Klotz's original patch to use perror instead of fprintf
when it fails to open /dev/btrfs-control

Chris Mason 6c771595af Modify the subvol and snapshot creation ioctls to work anywhere in the tree 
This changes the snapshot and subvol ioctl API and command lines so
that new snapshots and subvols can be created anywhere.

Subvolume creation hasn't changed much:

btrfsctl -S subvol_name directory

This creates a new subvolume under 'directory'

Snapshot creation looks the same, but is actually different:

btrfsctl -s full_path_to_new_snapshot file_or_dir

For example: btrfsctl -s /mnt/new_snap /mnt/subvol

Will create a new snapshot named new_snap under /mnt of the root
found in /mnt/subvol.  It always snapshots the entire root regardless of
which file or directory inside the root you give it.

Chris Mason 969c548acb Add sync and transaction ioctl defs 
btrfsctl -c forces a single FS sync

The transaction ioctls are unsafe for general use because they can lead
to deadlocks if the application is not very careful.  But, ceph is
experimenting with btrfs as a backing store, and these ioctls are required
for testing.
