Running this on sn-devel-184 takes ~14 seconds with the atomic
ops. Without them I did not wait for it to finish. After reducing
NPROCS from 500 to 50 it still ran for more than a minute.

With locking.tdb now based on g_lock.c code, we change locking.tdb a
lot more often. I have a customer case where LDX tortures smbd very
hard with 800+ concurrent connections, which now completely falls over
where 4.12 still worked fine. Some debugging showed a thundering herd
on fcntl locking.tdb index 48 (TDB_SEQNUM_OFS). We still use fcntl for
the seqnum, back when we converted the chainlocks to mutexes we did
not consider it to be a problem. Now it is, but all we need to do with
the SEQNUM is to increment it, so an __atomic_add_fetch() of one is
sufficient.
I've taken a look at the C11 standard atomics, but I could not figure
out how to use them properly, to me they seem more general to be
initialized first etc. All we need is a X86 "lock incl 48(%rax)" to be
emitted, and the gcc __atomic_add_fetch seems to do this.

SMB1search and trans2 findfirst are unique in that
they are the only passed in pathnames that can contain
a terminal wildcard component.
Deal with these two special cases with this new function
that strips off the terminal wildcard and returns as
the mask, and pass the non-wildcard parent directory
component through the standard filename_convert().
Uses new helper function strip_gmt_from_raw_dfs().
When SMB1search and trans2 findfirst have been
converted to use this function, we can strip all
wildcard handling out of filename_convert() as
we now know it will only ever be given valid
pathnames.

This one is subtle. If an SMB1 request has both a DFS path and a @GMT token,
the unix_convert() inside the DFS path processing will remove the @GMT
token, not allowing the subsequent unix_convert() inside filename_convert()
to see it. By returning it from dfs_redirect() we can ensure it's correctly
added to the smb_filename returned from filename_convert().
