  Add support for writing module unit tests

Developers may easily write module unit tests as follows:

    1. any testing code .c files must be placed in modules/<mod>/test/
    2. you must provide a "modules/<mod>/test/opensips.cfg" file for the
       module tests to run on top of
         (TODO: ideally, there should be support for multiple of these)
    3. the tests will be executed using an entry-point function,
       which _must_ be named "mod_tests:
	    typedef int (*mod_tests_f) (void);
    4. "make test module=registrar" in order to start OpenSIPS using
       your opensips.cfg and run your 'mod_tests' function
