Subject: Started working towards a more clean include hierarchy and
 distinguishable program modules. First step: move stuff from global headers
 that is only used in one source file to those source files.

include/rmdfunc.h
include/rmdmacro.h
include/rmdtypes.h: Move stuff from here

src/rmd_jack.c
src/get_frame.c
src/rmd_cache.c
src/load_cache.c
src/rectinsert.c
src/cache_frame.c
src/poll_events.c
src/setbrwindow.c
src/recordmydesktop.c: To here.
