The Makefile had the wrong CONFIG_ variable in it so that in
case GFS2 was y and the lock modules were m, they were not
getting built properly.

lm_interface.h has a few out of the tree clients such as GFS1
and userland tools.
Right now, these clients keeps a copy of the file in their build tree
that can go out of sync.
Move lm_interface.h to include/linux, export it to userland and
clean up fs/gfs2 to use the new location.

As requested by Jan Engelhardt, this removes the typedefs in the
locking module interface and replaces them with void *. Also
since we are changing the interface, I've added a few consts
as well.

This code is no longer used for anything and can be removed
from the locking modules. The sync_lvb function is not required
as this happens automatically with the current locking system.

This removes one of the typedefs from the locking interface. It
is replaced by a forward declaration of the gfs2 superblock. The
other two are not so easy to solve since in their case, they
can refer to one of two possible structures.

As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this
updates the copyright message to say "version" in full rather than
"v.2". Also incore.h has been updated to remove forward structure
declarations which are not required.
The gfs2_quota_lvb structure has now had endianess annotations added
to it. Also quota.c has been updated so that we now store the
lvb data locally in endian independant format to avoid needing
a structure in host endianess too. As a result the endianess
conversions are done as required at various points and thus the
conversion routines in lvb.[ch] are no longer required. I've
moved the one remaining constant in lvb.h thats used into lm.h
and removed the unused lvb.[ch].
I have not changed the HIF_ constants. That is left to a later patch
which I hope will unify the gh_flags and gh_iflags fields of the
struct gfs2_holder.

When the result of a posix lock request is read it needs to be matched up
with the correct waiting request. The owner field needs to be used in the
comparison since more than one process may be waiting for locks on the
same file.

Use the gfs2_ prefix on the register/unregister functions for the lock
modules. The gfs_ prefix was left from an old idea on how to share these
with gfs1.

We need to use fl_owner instead of fl_pid to track the owner of a posix
lock. Pass the owner value out to user space where cluster plocks are
managed.

Setup the lock_dlm kobject before setting up the dlm lockspace instead
of after. We want to use the sysfs files to detect the mount without
having to wait for the dlm setup which can take a while.

This patch contains the following possible cleanups:

- remove the following global function that was both unused and
unimplemented:

User space needs to know if the node actually recovered the journal or

Some interfaces have changed. In particular one of the posix
locking functions has changed prototype, along with the
address space operation invalidatepage and the block getting
callback to the direct IO function.
In addition add the splice file operations. These will need to
be updated to support AOP_TRUNCATED_PAGE before they will be
of much use to us.
