we were previously only verifying that the server didn't reboot between WRITEs. COMMIT returns a verifier that needs to be checked as well

it complained that mdls had to have a certain (undocumented) flag set.
also, it seemed to imply that in readdir, the locking of pages needed
to be done by the thread creating the mdl. so i moved the locking/unlocking
there.
if the nfs_mount passes us a read-only mount option. then return
access_denied if:
1. requests for open with desired access of write or append,
2. we get a write irp,
3. requests for setattr, setattrex, setacl
4. ignore the delete_on_open flag passed to open
on a mount request, search a list of existing mounts for a given netroot
based on LUID entries (login ids). if an entry is found, then check the
current request rpcsec flavor against existing sessions/mounts. If no
match found, do another upcall for a mount and store a session of this
flavor for this LUID. if no entry found for this LUID, then do a mount
upcall, create a new entry and add it to the list.
avoid unnecessary calls to SystemTimeToFileTime() in get_file_epoch() by hardcoding the FILETIME value of jan_1_1970

on CB_GETATTR, search for a delegation with the given filehandle. if found, use its fileid to get its cached attributes. when encoding the response, only include change and size attributes

the out_err_deleg: case of nfs41_name_cache_insert() was forgetting to increment cache->delegations, leading to a decrement past 0. once that happens, the cache stops accepting delegations because it's comparing cache->max_delegations against UINT_MAX

iozone tests were failing intermittently against emc-2 due to out-of-order LAYOUTCOMMITs that both specified new_last_offset
nfs41_open_state now maintains a cached value of the last_offset, and avoids sending it with LAYOUTCOMMIT unless the new last_offset is greater than the cached offset. this cached value is initialized on open/delegation, and updated on setattr for size

sorry, earlier Casey, but the patch 'threading by io unit instead of stripe' from 6/20/2010 was nuts! with PNFS_THREAD_BY_SERVER disabled, we definitely -don't- want to create a separate thread for each io unit (each READ/WRITE request to a ds). we just want the one per stripe, as the intended alternative to PNFS_THREAD_BY_SERVER

cancel_lock() can't rely on checking upcall.status, because a handle_lock() success could be overwritten by upcall_marshall() or failure to allocate the upcall reply buffer. added new flag lock_upcall_args.acquired for this purpose

now that cancel_lock() and handle_unlock() depend on finding lock state in the open, the comment /* ignore errors from open_lock_add(); they just mean we won't be able to recover the lock after reboot */ no longer applies. allocate the lock state at the top of handle_lock(), so we can bail immediately on failure
