isc_dpb_config is used in exactly the same way as any other DPB tag: <tag><1 byte value
length><value>. Value for it is a text from firebird.conf file, literally, in form
<param>=<value> separated by new lines.
Because of "hackish" nature of this tag, you'll get no indication if the value is
well-formed and applied or contain mistypes and was silently ignored.

But, actually, client library from Firebird 3.0 should work with server 2.5 "out of
box" without additional configuration.

At first, DPB is used in old API as well as in new one, no difference between them in
this respect.
At second, I personally think that in current form this new API must never leave internals.
