Patch from Mathieu Taillefumier

I modified some hearder file in ecore to ease the cleanup of the private
header files in ecore. Each module has now a private header with its own
log color (eina_log related). I also created two private header files
for ecore_sdl and ecore_input for this purpose and corrected some typos
in the xlib_xcb private header file.
