	* configure.in: Determine the suffix of the shared librarries for
	this system. This is done analogous to
	ltconfig.sh. G_MODULE_SUFFIX in glibconfig.h is set to either
	"sl", "dll", or (most often) "so".

	* tests/Makefile.am, tests/module-test.c,
	tests/libmoduletestplugin_a.c, tests/libmoduletestplugin_b.c:
	Added new testcase for gmodule. This is mostly copied from
	gmodule/testgmodule.c, but unlike that is is quiet. (Why BTW are
	some tests that verbose, not to say loquacious...)

	* gmodule.c: Make g_module_open more tolerant wrt to the module
	name. First it tries to open the module as named, if that fails,
	it checks, whether it is a libtool archive and parses it, if that
	fails it appends the systems shared library suffix
	(i.e. ".so") (if not already found) and tries again and if that
	fails it tries to append the ".la" libtool suffix (if not already
	found) and parses it.

	* gmodule.c: Lock recursive mutex during most module functions for
	safety.

	* gmodule-dl.c: Return an error from _g_module_symbol only, if
	dlerror says so. All other functions return an error as well, if
	dlerror returns NULL.

	* testgmodule.c: Thanks to the above change the #ifdefs have
	vanished.

	* glib/glib-sections.txt: Added G_MODULE_SUFFIX.

	* glib/tmpl/modules.sgml: Updated.

First of all g_module_open() tries to open @file_name as a module. If
that fails and @file_name has the ".la"-suffix (and is a libtool
archive) it tries to open the corresponding module. If that fails and
it doesn't have the proper module suffix for that plaform

module will be opended. If that fails and @file_name doesn't have the

open the corresponding module. If eventually that fails as well, NULL
is returned.
