	Added basic framework for plug-ins to access the use_cpu_accel
	configuration (bug #342860):

	* app/composite/gimp-composite.[ch]: added new function
	gimp_composite_use_cpu_accel().

	* libgimpbase/gimpprotocol.[ch]: added use_cpu_accel to the config
	message.

	* app/plug-in/gimppluginmanager-call.c: pass the return value of
	gimp_composite_use_cpu_accel() for config.use_cpu_accel.

	* libgimp/gimp.[ch]: make the config value accessible by means of
	a new function gimp_use_cpu_accel().

	* libgimp/gimp.def: updated.
