* gmodule-beos.c (_g_module_symbol): do not return NULL symbols.
* gmodule-os2.c: removed NetBSD specific defines.
(_g_module_self): set an error message for unsupported behaviour.
* gmodule-beos.c: many coding style fixups.
(_g_module_open):
(_g_module_self):
(_g_module_close):
(_g_module_symbol): bunch of memory leaks plugged.
* gmodule-dl.c: make sure the error message returned from dlerror()
is always != NULL, by using a wrapper function fetch_dlerror(). based
on a patch to fix _g_module_symbol() for NetBSD from Scott Presnell
<srp@zgi.com>.
* gmodule-dld.c: minor indentation.
* gmodule-win32.c: minor cleanups.
* merges from glib-1-2.
