These patches add FREE_STATEID and TEST_STATEID to the NFS server.  I
appreciate any comments, especially if there is a better way of doing things.

v2:
- FREE_STATEID
  - Free open, lock, and delegation state ids correctly
  - Use the check_for_locks() function to check for locks

- TEST_STATEID
  - Remove openmode check
  - Sanity check on size of stateid list
  - Delay decoding stateid list until encoding the reply

v3:
- FREE_STATEID
  - Open stateids and delegations are never freeable (return nfserr_locks_held)

- TEST_STATEID
  - Remove unused arguments from a function call
  - Store and use the HAS_SESSION flag for validating stateids

Thanks!

- Bryan
