when files on all backend nodes are missing, the logic in afr_sh_entry_erase_pending
is broken and results in missing lookup frame. this causes processes to enter into
uninterruptible sleep state.

fail revalidate calls if inoode number has changed for the basename at the server side. This is a temporary workaround for most of the cases till inode-gen is merged

Init the list structure, because it will be used later,
and subtract_lock does not do it.
Also remove the special handling for unlocks, which was
probably introduced as a workaround for this bug.

- this procedure processes inode_ctx to make decisions like whether the
current procedure can continue (i.e., inode is already looked up),
or the procedure has to initiate/wait for lookup on the path. It also
sets up the frame->local and adds the stub corresponding to current fop
if needed.

- change sp_lookup and sp_lookup_cbk to support sending lookups when needed.
lookups might need to be sent in fops like open, chmod, chown etc which
operate on a path, since the actual lookup sent to stat-prefetch by its
parent xlators is not propagated down the xlator tree if the path is
cached.

- lookup-behind should be done on-demand basis, in fops like open
instead of in sp_lookup itself. This would reduce network traffic
between client and server related to lookup, if the only use of
lookup was to fetch stat structure.

- sp_cache_get_inode uses fd_lookup which internally increases the refcount of
fd by 1. This needs to be unrefed once we get the cache.
- for directories, stat is stored in the inode context in sp_lookup_cbk.
but, while doing so, no check was being done for the presence of context
in inode, resulting in leak of memory equal to sizeof (struct stat) when
multiple lookups happened on the directory. stat was needed to serve the
postparent member during lookup. postparent stat is needed only in releases
having NFS related changes and hence removing code present to get
postparent.
- path constructed in sp_readdir was not freed.

fixes the race where a subvolume might go down during the transaction

- for non-write wind requests, the request structure outlives the stub.
The call stub is destroyed when stack is wound but request is destroyed
only when the reply has come.
(for writes, both stub and request are destroyed when refcount becomes 0,
which happens only when the write operation is stack unwound and a reply
for the write operation has come from underlying translators, for non-write
unwind requests the request is first destroyed before resuming the stub).
