patching for darwin

The attached patch, and the use of bash rather than zsh, reduces the number of
failed tests to one - the last failure being hardcode.test, which I haven't
really looked at in any detail.

A fix for everybody's favourite darwin bug (the convenience lib. thingy) is
included. It's improved from my original submission in June and doesn't seem
to break anything. We even have the latest CVS glib & gtk+ building now!
(I'm told it fixes only the symptoms, not the problem, but it's a start.)

The module loader is derived from Dan Winship's gmodule-dyld. I've reworked
it as a dlopen/dlclose/etc. interface for direct inclusion in ltdl.c but also
as a standalone file in case anybody wants to use it elsewhere. (I'm very new
to modules and there are still some issues to be addressed, so to speak...)

The only thing I'm really uncertain about is the 'fix' (\\\"\1\\\" -> \"\1\")
for lt_cv_sys_global_symbol_to_c_name_address where I have changed the two
instances but perhaps it would be better to add a third darwin-specific case?

Anyway, I'd be grateful if people could test the patch. Here's a sample
