Add an nfs4 operations count array to nfsd_stats structure. The count is
incremented in nfsd4_proc_compound() where all the operations are handled
by the nfsv4 server. This count of individual nfsv4 operations is also
entered into /proc filesystem.

NFSv4 allows for the fact that filesystems may be replicated across
several servers or that they may be migrated to a backup server in case of
failure of the primary server.
fs_locations is an NFSv4 operation for retrieving information about the
location of migrated and/or replicated filesystems.
Based on an initial implementation by Jiaying Zhang <jiayingz@citi.umich.edu>

We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the
fh_expire_type attribute. This is incorrect:
1. The spec actually only allows NOEXPIRE_WITH_OPEN when
VOLATILE_ANY is also set.
2. Filehandles for open files can expire, if the file is removed
and there is a reboot.
3. Filehandles are only volatile on rename in the nosubtree check
case.
Unfortunately, there's no way to indicate that we only expire on remove. So
our only choice is FH4_VOLATILE_ANY. Although it's redundant, we also set
FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually
cause problems in practice and it seems possibly useful to give clients some
way to distinguish that case.
Fix a mispelled #define while we're at it.

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!
