added delegation.c and .h
nfs41_client stores a list of nfs41_delegation_state
new function nfs41_delegate_open() to look for a compatible delegation before calling nfs41_open()
if nfs41_open() is granted a delegation, call nfs41_delegation_granted() to register it with the client
client calls nfs41_client_delegation_free() on unmount to free list of delegations

moved state data (stateid, flags, locks, and reference counts) out of struct pnfs_layout, which should represent a layout segment returned by LAYOUTGET
struct pnfs_layout_state now holds this state, along with a pointer to a single pnfs_file_layout
struct pnfs_file_layout_list is now a list of pnfs_layout_states, and was renamed to pnfs_layout_list

server_create() was ignoring the return value of nfs41_name_cache_create(), but it needs to be propagated all the way back through nfs41_server_find_or_create() to nfs41_client_create() and nfs41_client_renew()

moved recovery-related fields into struct nfs41_client.recovery. now uses a com
bination of CRITICAL_SECTION and CONDITION_VARIABLE for use with SleepConditionV
ariableCS()
renamed check_renew_in_progress() to recovery_start_or_wait(), and fixed the loc
king so that we atomically check/set in_recovery
when recovery is finished (including error conditions), call recovery_finish() t
o reset the recovery status and wake any waiting threads

open state is added to the client's list on a successful call to nfs41_open(), and removed from the list on nfs41_close() regardless of success

fixed a few cases of warning 4242: possible loss of data
wincrypt.h appears to come with windows.h in later versions of the ddk, but nfs41_client.c fails to compile in WDK 6001 without #include <wincrypt.h>
