Commit 810397f89a, and possibly others, broke the build for macOS and
other environments which don't have st_[acm]tim fields on 'struct stat'.
Multiple places in the codebase used the config.h values to determine
how to access the nanosecond or microsecond values of the stat
timestamps, so rather than add more, centralize them all into
lib/util/time.c.
Also allow pvfs_fileinfo.c to read nanosecond-granularity timestamps on
platforms where it didn't before, since its #if branches were not
complete.

We don't require a sequence number that is incremented,
we just need a value that's not reused.
We use the new generate_unique_u64(), which is much cheaper!
Using smbtorture3 //foo/bar -U% local-g-lock-ping-pong -o 500000

Same concept as dbwrap_watched_watch_send/recv: Get informed if the
underlying data of a record changes. This utilizes the watched
database that g_lock is based upon anyway. To avoid spurious wakeups
by pure g_lock operations this patch adds a sequence number for the
data that is stored in the g_lock data field.

Most places take twrp from a local struct smb_filename variable that the
function is working on. Some don't for various reasons:
o synthetic_smb_fname_split() is only called in very few places where we don't
expect twrp paths
o implementations of SMB_VFS_GETWD(), SMB_VFS_FS_CAPABILITIES() and
SMB_VFS_REALPATH() return the systems view of cwd and realpath without twrp info
o VFS modules implementing previous-versions support (vfs_ceph_snapshots,
vfs_shadow_copy2, vfs_snapper) synthesize raw paths that are passed to VFS NEXT
functions and therefor do not use twrp
o vfs_fruit: macOS doesn't support VSS
o vfs_recycle: in recycle_create_dir() we need a raw OS path to create a directory
o vfs_virusfilter: a few places where we need raw OS paths
o vfs_xattr_tdb: needs a raw OS path for SMB_VFS_NEXT_STAT()
o printing and rpc server: don't support VSS
o vfs_default_durable_reconnect: no Durable Handles on VSS handles, this might
be enhances in the future. No idea if Windows supports this.
o get_real_filename_full_scan: hm.... FIXME??
o get_original_lcomp: working on a raw path
o msdfs: doesn't support VSS
o vfs_get_ntquota: synthesizes an smb_filename from ".", so doesn't support VSS
even though VFS modules implement it
o fd_open: conn_rootdir_fname is a raw path
o msg_file_was_renamed: obvious
o open_np_file: pipes don't support VSS
o Python bindings: get's a raw path from the caller
o set_conn_connectpath: raw path
o set_conn_connectpath: raw path
o torture: gets raw paths from the caller
