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.

[Don't use this stuff if you're easily offended by changes to the
interface or behaviour - it's still work in progress.]

PR:

  1. Added code to the memory leak detecting code to give the user the
     possibility to add information, thereby forming a traceback.

  2. Make the memory leak detecting code multithread-safe.

The idea is that we're actually dealing with two separate critical
sections, one containing the hash tables with the information, the
other containing the current memory checking mode.  Those should not
be handled with the same lock, especially since their handling overlap.
Hence, the added second lock.

DSA_METHOD to make it more consistent with RSA_METHOD.

use new file buildinf.h instead.

thread-safe (where thread-safe counterparts are not available on all
platforms), and don't memcpy to NULL-pointers

Also, clean up htons vs. ntohs confusions.
