log_ctx.log_private was used uninitialized. Not a real bug here,
as tdb_log does not access it, but tdb_open_ex still moves around
uninitialized data. So this would show up in valgrind as well.

In reviewing various files in Samba-4.0.7, I found a number
of instances where malloc()/calloc() were called without the
checking the return value for a value of NULL, which would
indicate failure.
(NB. The changes needed to ccan, iniparser, popt and heimdal
will be reported upstream, not patched inside Samba).

realloc(NULL, ...) is equivalent to malloc. We are already using this
realloc property for tdb->lockrecs. It should not make any difference
in speed, it just makes for a little simpler code.

For the mutex code we will have to lock the hashchain and the record

it's a small refactoring for the better anyway I think.

lock-tracking.c mirrors the in-kernel fcntl structures to detect
unexpected use of fcntl calls. During my mutex work I changed our fcntl
use so that we unlock the allrecord_lock in two pieces: The range covering
the hash locks and the range covering the data area for the individual
traverse record locks. Splitting locks is not covered by lock-tracking.c.
This patch extends lock-tracking.c with this little piece. It's still
far from complete to track the full range of fcntl semantics. It is not
strictly needed right now, but it does not hurt either.
