rees 108fca056b NFSv4 fixes from Connectathon 2004:
remove unused pid field of file context struct
map nfs4 error codes to errnos
eliminate redundant code from nfs4_request
use zero stateid on setattr that doesn't set file size
use same clientid on all mounts until reboot
invalidate dirty bufs in nfs4_close, to play it safe
open file for writing if truncating and it's not already open
