ocfs2: Userspace cluster stack support

These patches allow ocfs2 to use the distributed lock manager in fs/dlm
in conjunction with a userspace cluster stack.

This series builds on the stack-glue series sent previously.  It
provides a plug-in for userspace cluster stacks and fs/dlm.  Userspace
is responsible for communicating with the cluster stack and feeding
events through the ocfs2_control misc device.  ocfs2 is otherwise
agnostic, using the DLM for all of its interaction.

Using the new ocfs2_stack_user plug-in requires a development version of
the ocfs2 tools.  This version knows how to load the plug-in and
provides a daemon to interact with the cman cluster stack.

The second to last patch enables the plug-in in Kbuild.  The last patch
adds Kconfig options to select which ocfs2 cluster plug-ins get built.

The kernel code is also available on the 'stack-user' branch of my git
repository.
