This clarifies the code a little, but also provides a more explicit
mechanism which can be used to debug error handling (by introducing
tdb_err_t and making it a pointer type).

Finally, we split out the tdb2-specific parts of tdb_context, and put
them into a "tdb2" sub-struct; the tdb1 parts go into a "tdb1"
sub-struct. We get rido of tdb1_context and use tdb_context
everywhere.

You can only unset it if the TDB was originally opened O_RDWR.
Also, cleaned up error handling in tdb_allrecord_lock() so we only get
one log message on a r/o database.

It's more consistent with what tdb1 does, and slightly more encapsulated.

The tdb_oob() function can fail due to errors, as well as because the length
asked for is greater than the size of the file. Clean that up:
(1) If probe is true, only fail if there's an error, not if the length is
too great.
(2) Exit tdb_open() if it tdb_oob() probe fails; this helps cut down
test time for failtest.
(3) Don't set probe to true in tdb_direct() fail; a minor issue, but it means
we log failure.
