deleg: use delegations to satisfy opens locally

Browse source 
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
