[samba-tng] EXCELLENT!

[Luke Kenneth Casson Leighton]

a combination of tdb.c and parse_prs.c brings about some REALLY powerful
code.

the ability to optimally store arbitrary-size binary data structures in a
database.  the only thing that's going to HAVE to be done to make sure
that this works is that because the keys are compared by memcmp(),
parse_prs.c is going to HAVE to be modified to ensure that it zeros all
unused alignment bytes.

see prs_tdb_store and prs_tdb_fetch.
