Subject: src/recordmydesktop.h: Move away the [yuv]blocks globals.

src/yuv_utils.h: Move out the DBUF- and the MARK_BACK_BUFFER_C() macros.

src/block_utils.[ch]: New files hosting the [yuv]blocks globals and DBUF-macros.

src/get_frame.c: Put MARK_BACK_BUFFER_C() locally here.

src/Makefile.am
src/rmd_rescue.c
src/cache_frame.c
src/initialize_data.c: Adapt to changes.
