        * glib/glib/gtestutils.c: print out random seed for verbose tests,
        also adapted test result reporting slightly in verbose mode to allow
        custom debugging output. support "thorough" as test mode alis for "slow".

        * glib/glib/gtestutils.h: added g_test_thorough().

        * glib/glib/gtester.c: print out the last random seed when tests fail.
        added result attribute to test case status logging to easily spot
        failing tests in log files. disabled debugging output when skipping tests.
