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.

This is mostly a search and replace as ocfs2_journal_handle is now no more
than a container for a handle_t pointer.

ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.

All callers either pass in NULL directly, or a local variable that is
already set to NULL.

The internals of ocfs2_start_trans() get a nice cleanup as a result.

It is no longer used.

This sets us up to remove handle->journal.

This is no longer used outside of journal.c

This gets us rid of a slab we no longer need, as well as removing the
majority of what's left on ocfs2_journal_handle.

ocfs2_commit_unstarted_handle() has no more real work to do, so remove that
function too.

We can also delete the unused infrastructure which was once in place to
support this functionality. ocfs2_inode_private loses ip_handle and
ip_handle_list. ocfs2_journal_handle loses handle_list.

Callers can set h_sync directly on the handle_t, whether a transaction has
been started or not can be determined via the existence of the handle_t on
the struct ocfs2_journal_handle.

No reason to use our wrapper struct in this function, so take the handle_t
directly.

Also fixes a bug where we were incorrectly setting the handle to NULL in
case of a failure from journal_restart()

max_buffs was just being set and not actually used.

Fix up for make allyesconfig.

Disable automatic checkpointing of the journal - this is a relic from older
ocfs2 days. Worth quite a bit of performance on longer running single node
tests.
