HP/UX dynamic loading (was: Re: rePorting)

Looking at Python's dynamic loading, it always goes for shl_load().

But... Branko actually indicated there was a problem with the
apr_dso_handle_t type not being seen. I'd guess there is a simple problem
somewhere with the headers.

The code below can/should probably be tweaked some to use autoconf
mechanisms rather than the platform defines. Python has got quite a bit of
this stuff already autoconfiscated, so we could probably snarf a good amount
from there.

Cheers,
