We can't use LKM_LOCAL for new dentry locks because an unlink and subsequent
re-create of a name/inode pair may result in the lock still being mastered
somewhere in the cluster.

Actually replace the vote calls with the new dentry operations. Make any
necessary adjustments to get the scheme to work.

Uptodate.c now knows about read-ahead buffers. Use some more aggressive
logic in ocfs2_readdir().
The two functions which currently use directory read-ahead are
ocfs2_find_entry() and ocfs2_readdir().

Remove the redundant "i_nlink >= OCFS2_LINK_MAX" check and adds an unlinked
directory check in ocfs2_link().

The dir nlink check in ocfs2_mknod() was being done outside of the cluster
lock, which means we could have been checking against a stale version of the
inode. Fix this by doing the check after the cluster lock instead.
