r19685: Two changes inspired by problems with huge tdbs. tdbtool's list command now

prints the hash on every record for easier awk'ing, and tdbbackup allows a
different hash chain length on the backed up tdb.

Jeremy, Günther, this might be interesting for you huge domains. Not only
locking.tdb, also the winbind ones might grow huge.

In the installation I fixed with this winbind spent a huge amount of CPU
spinning through a degenerated winbindd_idmap.tdb with entries for more than
15.000 users. With a default number of hash chains of 131 on that tdb you can
imagine that the lists get large.

Not merging to 4, I don't get tdbbackup to compile there right now.

What about changing the global default hash chain number to be dramatically
larger? Disk is cheap these days.
