Add --with-systemd / --without-systemd options to check whether

startup status to systemd for smbd/winbindd/nmbd and AD DC.
The problem it solves is correct reporting of the Samba services

When in tdb_store we re-use a dead record reactivated from the
target hash chain itself, we currently leave it in its place in
the chain. When we re-use a dead record from a different chain or
from the freelist instead, we insert it at the beginning of the
target chain.
This patch changes the behaviour to always newly store a
record at the beginning of the hash chain. This removes
a special case and hence simplifies the allocation code.
On the other hand side, it introduces two additioal tdb_ofs_write
calls for the in-chain-case.
Note the subtelty of the patch that by moving the case of the candidate
record's chain as new case "i=0" into the for loop, we also reverse the
order of the two steps in the for-loop body (non blocking freelist alloc
and searching for dead record in a chain) in order to keep the overall
order of execution identical.

In a metadata-intensive benchmark we have seen the locking.tdb freelist to be
one of the central contention points. This patch removes most of the contention
on the freelist. Ages ago we already reduced freelist contention by using the
even much older DEAD records: If TDB_VOLATILE is set, don't directly put
deleted records on the freelist, but just mark a few of them just as DEAD. The
next new record can them re-use that space without consulting the freelist.
This patch builds upon the DEAD records: If we need space and the freelist is
busy, instead of doing a blocking wait on the freelist, start looking into
other chains for DEAD records and steal them from there. This way every hash
chain becomes a small freelist. Just wander around the hash chains as long as
the freelist is still busy.
With this patch and the tdb mutex patch (following hopefully some time soon)
you can see a heavily busy clustered smbd run without locking.tdb futex
syscalls.

This makes cross-compiling happy, use a trick similar to autoconf's
AC_CHECK_SIZEOF macro.
Basically we make an array:
static int array[1 - 2 * !(((long int)(sizeof(off_t))) < 8)];
This gives -1 multiplied by the negation of the condition
(sizeof(off_t) < 8) cast to a long int.
So if the condition is true it gives array[(-1 * 0)] (remember the
condition is cast and negated) thus passing a build test with a 0-sized
array.
If it's false it gives array[(-1 * 1)] thus failing with a
negative-sized array.

Make the lock/unlock bracket more obvious by extracting
locking (and finding) from the special cases to the top
of the function. This also lets us take lock and find
the record outside the special case branches (use dead
records or not).
There is a small semantic change implied:
In the dead records case, the record to delete is looked
up before the current dead records are potentially purged.
Hence, if the record to delete is not found, the dead
records are also not purge. This does not make a big
difference though, because purging is only delayed until
directly befor the next record to delete is in fact found.
