Fix prototype of dbm_open().

The last argument of dbm_open() should be a mode_t according to POSIX;
not an int.

Let dbm's datum::dptr use the right type.

According to POSIX, it should use void *, not char *. Unfortunately, the
dsize field also has the wrong type. It should be size_t. I'm not going
to change that, as that will break the ABI.

mdoc(7) police: Use the new .In macro for #include statements.

mdoc(7) police: replace `\*(Ba' with a simple `|', it's handled specially.

Remove duplicate words.

mdoc(7) cleanup.

Add a man page for the dbm_* functions, and update the Makefile to link
it in.

Some review from -hackers (some time ago), and I think the best way to
get this improved (if it needs improving) or updating, is to bring it in.
