[Patches] (BSP 11.09.01 GA) camera/gstreamer/glib applications

Hi,

Working with a camera application recently I received the following two patches from factory that fix issues with glib (gprint) and gst-fsl-plugins (framerate):

Heard from EricNelson that more people had same issues, so it would be good to share.

There you go:

For glib:

Thanks for the patches, but could you also please give some explanation/reason for it? e.g. what the problems without have been in detail (e.g. with gprint?)

Without glib patch, g_print would crash, for instance, where a %p was used.

These patches are not necessary with the new BSP (L3.0.35_1.1.0_SOURCE), which I would suggest using instead.
