db5bda56bf tdb: add TDB_MUTEX_LOCKING support
This adds optional support for locking based on
shared robust mutexes.

The caller can use the TDB_MUTEX_LOCKING flag
together with TDB_CLEAR_IF_FIRST after verifying
with tdb_runtime_check_for_robust_mutexes() that
it's supported by the current system.

The caller should be aware that using TDB_MUTEX_LOCKING
implies some limitations, e.g. it's not possible to
have multiple read chainlocks on a given hash chain
from multiple processes.

Note: that this doesn't make tdb thread safe!

3c4263e758 tdb: don't use err.h in tests.
It's not portable.  While we could use ccan/err, it seems overkill since
we actually only use it in one test (I obviously cut & paste the #include).

3272ba0d2d lib/tdb: remove unnecessary XOPEN and FILE_OFFSET_BITS defines in test/
These were relics: they don't need to be defined here as long as we are
careful to include the replace headers before any standard headers (we are).

205242e176 tdb/test: fix up tests for use in SAMBA tdb code.
1) Make sure we include "tdb_private.h" first, to get the right headers
   (esp. the correct setting of _FILE_OFFSET_BITS before unistd.h).
2) Fix 3G file test since expand logic has changed.
3) Fix nested transaction test, since default is to allow nesting.
4) Capture fdatasync, which was slowing down transaction expand.

8fa345d952 tdb: wean CCAN-style unit tests off of tap.
We could use subunit, but that's overkill.  Just print messages when
we fail, and use exit status.

0802791081 tdb: import unit tests from CCAN into tdb/test/
I pulled tdb into CCAN as an experiment a while ago; it doesn't belong
there, but it has accumulated some important unit tests.

These are copied from CCAN version init-1486-gc438ec1 with #include "../"
changed to #include "../common/".
