Rick Macklem 3f7e14ad93 nfscl: Add hash lists for the NFSv4 opens 
A problem was reported via email, where a large (130000+) accumulation
of NFSv4 opens on an NFSv4 mount caused significant lock contention
on the mutex used to protect the client mount's open/lock state.
Although the root cause for the accumulation of opens was not
resolved, it is obvious that the NFSv4 client is not designed to
handle 100000+ opens efficiently.  When searching for an open,
usually for a match by file handle, a linear search of all opens
is done.

This patch adds a table of hash lists for the opens, hashed on
file handle.  This table will be used by future commits to
search for an open based on file handle more efficiently.
