This adds gives Cogl a dedicated UProf context which will be linked together with Clutter's context during clutter_init_real(). Initial timers cover _cogl_journal_flush and _cogl_journal_log_quad You can explicitly ask for a report of Cogl statistics by exporting COGL_PROFILE_OUTPUT_REPORT=1 but since the context is linked with Clutter's the statisitcs will also be shown in the automatic Clutter reports.
