Add file_utimens RPC to use a struct timespec

and update the servers to use UTIME_NOW and UTIME_OMIT.

* console-client/trans.c (netfs_attempt_utimes): Do not set current time
ourself.
* console/console.c (netfs_attempt_utimes): Likewise.
* ftpfs/netfs.c (netfs_attempt_utimes): Likewise.
* hostmux/node.c (netfs_attempt_utimes): Likewise.
* usermux/node.c (netfs_attempt_utimes): Likewise.
* nfs/ops.c (netfs_attempt_utimes): Likewise.
* doc/hurd.texi (file_utimens): Add documentation.
* hurd/fs.defs (file_utimens): Add RPC.
* libdiskfs/file-utimes.c (diskfs_S_file_utimes): Move implementation
and replace with translation layer with...
(diskfs_S_file_utimens): ... new function.
* libnetfs/file-utimes.c (netfs_S_file_utimes): Likewise with...
(netfs_S_file_utimens): ... new function.
* libnetfs/init-init.c: Include <error.h>.
(netfs_mtime): New variable.
(netfs_init): New function.
* libnetfs/netfs.h (netfs_attempt_utimes): Update documentation.
* libnetfs/priv.h (netfs_mtime): Declare variable.
* libtreefs/s-file.c (treefs_S_file_utimes): Convert time values and
call treefs_s_file_utimens instead of treefs_s_file_utimes.
* libtreefs/treefs-hooks.h: Replace TREEFS_HOOK_S_FILE_UTIMES with
TREEFS_HOOK_S_FILE_UTIMENS.
* libtreefs/treefs-s-hooks.h: Replace s_file_utimes with s_file_utimens.
* libtrivfs/file-utimes.c (trivfs_S_file_utimens): New function.
* libtrivfs/times.c (trivfs_set_atime): Try to use file_utimens before
using file_utimes.
(trivfs_set_mtime): Likewise.
* nfsd/ops.c (complete_setattr): Likewise.
* trans/fakeroot.c (netfs_attempt_utimes): Likewise.
* nfs/nfs.c (xdr_encode_sattr_times): Do not set atime or mtime when
they are NULL.
* configure.ac: Look for file_futimens, and define UTIME_NOW/OMIT, for
compatibility with old glibcs.
