This patch rips out the XFS ACL handling code and uses the generic
fs/posix_acl.c code instead. The ondisk format is of course left
unchanged.
This also introduces the same ACL caching all other Linux filesystems do
by adding pointers to the acl and default acl in struct xfs_inode.

Kill the quota ops function vector and replace it with direct calls or
stubs in the CONFIG_XFS_QUOTA=n case.
Make sure we check XFS_IS_QUOTA_RUNNING in the right spots. We can remove
the number of those checks because the XFS_TRANS_DQ_DIRTY flag can't be set
otherwise.
This brings us back closer to the way this code worked in IRIX and earlier
Linux versions, but we keep a lot of the more useful factoring of common
code.
Eventually we should also kill xfs_qm_bhv.c, but that's left for a later
patch.
Reduces the size of the source code by about 250 lines and the size of
XFS module by about 1.5 kilobytes with quotas enabled:
text data bss dec hex filename
615957 2960 3848 622765 980ad fs/xfs/xfs.o
617231 3152 3848 624231 98667 fs/xfs/xfs.o.old
Fallout:
- xfs_qm_dqattach is split into xfs_qm_dqattach_locked which expects
the inode locked and xfs_qm_dqattach which does the locking around it,
thus removing XFS_QMOPT_ILOCKED.

Currently we call from the nicely abstracted linux quotaops into a ugly
multiplexer just to split the calls out at the same boundary again.
Rewrite the quota ops handling to remove that obfucation.

Move the inode tracing into xfs_iget.c / xfs_inode.h and kill xfs_vnode.c

There's almost nothing left in this function, instead remove the IRELE
on the real times inodes and the call to XFS_QM_UNMOUNT into xfs_unmountfs.
For the regular unmount case that means it now also happenes after dmapi
notification, but otherwise there is no difference in behaviour.

The sync code in XFS is spread around several files. While it used to make
sense to have such a distribution, the code is about to be cleaned up and
so centralising it in one spot as the first step makes sense.

Use the generic set, get and removexattr methods and supply the s_xattr
array with fine-grained handlers. All XFS/Linux highlevel attr handling is
rewritten from scratch and placed into fs/xfs/linux-2.6/xfs_xattr.c so
that it's separated from the generic low-level code.

Makefile (and Kbuild) would include Makefile-linux-26 I doubt XFS will
really still compile on 2.4; so drop that. This moves Makefile-linux-26
into Makefile and drops Kbuild. Also having wrappers as both Kbuild and
Makefile seemed redundant anyways.
The patch is relatively large because it renames a file, but no functional
changes.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
