This reverts commit 4439876a34f2e5d19db0d8b05ce7d7722c1c466f.
This revert is necessary for path handle resolution to work over the
protocol where client/server talk only with the path, without inode
or parent inode and generation numbers

This patch solves the lock bailout problem seen recently when autoconf tools were run. This is a workaround,
where 'flock' locks are removed in pl_release, if an explicit UNLCK call does not come. The complete fix would
be to allow 'fcntl' and 'flock' locks to operate in different domains.

failed in sp_process_inode_ctx.
We need this patch for following reasons:
1. The inode used in the successful lookup call may not be the one passed to
fops operating on path. This may happen, if revalidate of inode is failed,
but the lookup itself succeeds (in case of reavalidate failures, fuse
sends a fresh lookup using new inode) and since inode_link, if there is an
inode already associated with a path retains it.
2. Only fops that "wait" in stat-prefetch for a lookup which is already in
progress, need to check for the result of the lookup they are waiting on,
before resuming and sp_process_inode_ctx is _not_ used in such contexts.

If both truncate & setattr need to be sent from fuse_setattr,
they are now sent one after the other (setattr first, and then truncate)
instead of being sent parallelly. The earlier code that sent them parallelly
had a couple of problems:
1) A bug in the logic that would sometimes cause the setattr call
to never return, making the application hang.
2) A possibility that truncate and setattr would race at the server/io-threads/posix
end, thus returning the wrong stat structure to the application.
This patch also removes an unneccessary "can_fuse_return" call in
fuse_attr_cbk, which would cause a call to hang if STAT or FSTAT failed.

Support for auxiliary group ids is needed for transmission
of more than one group id right through the xlator tree
so that posix can use these group ids to perform
in-house permission tests. The in-house permission checks are
needed so that we do not have to depend on non-POSIX calls
like setfs[ug]id for changing the user for each fop.
The setfs[ug]id are also limited since they do not allow setting
multiple group id as required for operation with NFS, which sends
us all the group ids for a process issuing file system requests.
