Btrfs: don't clean old snapshots on sync(1)
Cleaning old snapshots can make sync(1) somewhat slow, and some users
and applications still use it in a global fsync kind of workload.
This patch changes btrfs not to clean old snapshots during sync, which is
safe from a FS consistency point of view. The major downside is that it
makes it difficult to tell when old snapshots have been reaped and
the space they were using has been reclaimed. A new ioctl will be added
for this purpose instead.
