include/recordmydesktop.h: Get rid of YUV data variables (which were

insanely *defined* in this header (like the other globals)).

include/rmdmacro.h: Get rid of YUV utility macros.

src/initialize_data.c: Get rid of MakeMatrices() and include the new yuv_utils.h.

src/yuv_utils.[ch]: New files to host the YUV data variables and the
MakeMatrices() function. The globals are now properly defined in
the .c and exposed in the .h which also contains the YUV utility macros.

src/get_frame.c
src/update_image.c: Include the new yuv_utils.h

src/Makefile.am: Added yuv_utils.[ch].
