variety of platforms. A few are missing, and they will be added in
eventually, but as this is new stuff, it was better to not break lots of
platforms in one go that we can't easily test. The changes to "Configure"
should illustrate how to add support to other systems if you feel like
having a go.

NB: I'll add something shortly to allow you to add "dlfcn.h" support on
those platforms that don't have (or need) a dlfcn.h header file. (The
symbol for Configure will probably by "dlfcn_no_h").

Thanks to Richard Levitte, who is responsible for the dso_dl.c support,
understanding the trickier aspects of the build process, and giving great
feedback on everything else.

interface or behaviour - it's still work in progress.]

PR:

the build process (an upcoming commit no doubt), and is very much *new*
code - what that means is that it compiles ok - usually. It certainly
doesn't mean it runs well or even properly yet. Please don't muck round
with this unless you're looking to help out and hunt bugs. :-)

Currently this code doesn't have any support for controlling the "load"
behaviour (eg. paths, filename translations, etc). That'll be handled
using DSO_ctrl() and various flags, once we work out a sensible set of
flags.

it's a good thing if ssleay_rand_status() would do the corresponding
