Chris Mason 3c69faecb8 Btrfs: Fold some btree readahead routines into something more generic. 
Signed-off-by: Chris Mason <chris.mason@oracle.com>

Chris Mason 9f3a742736 Btrfs: Do snapshot deletion in smaller chunks. 
Before, snapshot deletion was a single atomic unit.  This caused considerable
lock contention and required an unbounded amount of space.  Now,
the drop_progress field in the root item is used to indicate how far along
snapshot deletion is, and to resume where it left off.

Chris Mason 4b52dff6d3 Btrfs: Fix super block updates during transaction commit 
The super block written during commit was not consistent with the state of
the trees.  This change adds an in-memory copy of the super so that we can
make sure to write out consistent data during a commit.
