Add HAVE_(UNIX_)DLAPI config header define

..., add the configure test flags and rename DLOPEN_LIBS to
UNIX_DLAPI_LIBS.

Initinally convert two dlsym callers to use HAVE_DLAPI and
osl_getAsciiFunctionSymbol.

There are a lot of places, which still use -ldl and even more
direct dlsym calls; good opportunity for many simple EasyHacks.
