LAYOUTGET xdr now supports decoding of multiple layout segments, which are returned in a list with pnfs_layoutget_res_ok
LAYOUTRETURN no longer operates on an existing pnfs_file_layout. it now takes a copy of the layout stateid, and returns the new stateid with pnfs_layoutreturn_res

operations that require a stateid now take stateid_arg for recovery information. these operations include close, setattr, lock/unlock, layoutget, and read/write (including pnfs)
nfs41_open_stateid_arg() locks nfs41_open_state and copies its stateid into a stateid_arg
nfs41_lock_stateid_arg() locks nfs41_open_state.last_lock and copies its stateid into a stateid_arg; if there is no lock state, it falls back to nfs41_open_stateid_arg()
pnfs_read/write() now take nfs41_open_state so they can generate stateid_args

added optional symlink argument to nfs41_create(), used when type is NF4LNK
changed createttype4.u.lnk.linkdata from char[] to const char* and updated encoding in nfs41_xdr.c

added time_delta argument to xdr_settime4(). if the normal 'time' argument is within time_delta of the current time (get_nfs_time()), it uses time_how=SET_TO_SERVER_TIME4. otherwise, it uses SET_TO_CLIENT_TIME4 and encodes the time as usual
handle_nfs41_setattr() ignores times if superblock->cansettime==0. otherwise, it passes in superblock->time_delta (via info.time_delta) along with the other time attributes, for use with xdr_settime4()

added FILE_FS_ATTRIBUTE_INFORMATION and FileSystemAttributes flags to from_kernel.h
queries case_preserving, case_insensitive attributes to fill in FileSystemAttributes, and uses #defines from nfs41_const.h for MaximumComponentNameLength and FileSystemName
