shape input of windows.

* Ecore ecore_main.c: Fixed ecore_main_loop
(_ecore_main_loop_iterate_internal). This fixes fd handler pending
issue when ecore_idler callback adds ecore_job/event.
* Ecore ecore_main.c: Refactoring _ecore_main_loop_iterate_internal().

* Ecore_X: introduce ecore_x_screen_size_get()
* Ecore_Evas: be safer when returning Ecore_Evas* from
ecore_evas_ecore_evas_get()
* Ecore_Evas: introduce ecore_evas_screen_geometry_get()
2011-05-30 Cedric Bail
* Add ecore_pipe_freeze/thraw to suspend and restart watching the pipe
inside the main loop.
