Mark Fasheh dcd0538ff4 ocfs2: sparse b-tree support
Introduce tree rotations into the b-tree code. This will allow ocfs2 to
support sparse files. Much of the added code is designed to be generic (in
the ocfs2 sense) so that it can later be re-used to implement large
extended attributes.

This patch only adds the rotation code and does minimal updates to callers
of the extent api.

Tiger Yang 500086300e ocfs2: Remove delete inode vote
Ocfs2 currently does cluster-wide node messaging to check the open state of
an inode during delete. This patch removes that mechanism in favor of an
inode cluster lock which is taken at shared read when an inode is first read
and dropped in clear_inode(). This allows a deleting node to test the
liveness of an inode by attempting to take an exclusive lock.

We can't do u64/u32 in kernel.

Mark Fasheh 8903901dbf ocfs2: Synchronize feature incompat flags in ocfs2_fs.h
These got a little bit out of date with ocfs2-tools, make things consistent
again. We reserve a flag for sparse allocation code as that's pretty close
to testable at this point.

Sunil Mushran c271c5c22b ocfs2: local mounts
This allows users to format an ocfs2 file system with a special flag,
OCFS2_FEATURE_INCOMPAT_LOCAL_MOUNT. When the file system sees this flag, it
will not use any cluster services, nor will it require a cluster
configuration, thus acting like a 'local' file system.
