build: Move build-system-related helper files to a separate subdirectory This unclutters the top-level directory and groups related files together.

Move addition of MMX-OBJS to OBJS into common.mak instead of duplicating it. Originally committed as revision 18478 to svn://svn.ffmpeg.org/ffmpeg/trunk

build: Fine-grained link-time dependency settings Previously, all link-time dependencies were added for all libraries, resulting in bogus link-time dependencies since not all dependencies are shared across libraries. Also, in some cases like libavutil, not all dependencies were taken into account, resulting in some cases of underlinking. To address all this mess a machinery is added for tracking which dependency belongs to which library component and then leveraged to determine correct dependencies for all individual libraries.

SKIPHEADERS := $(SKIPHEADERS:%=$(SUBDIR)%)
build: change checkheaders to use regular build rules Many compilers need special flags to compile *.h files as regular source code, if they will do so at all. Rather than hoping all compilers will have such a flag and adding mappings for it, create wrapper .c files for test building single headers. This allows using the regular rule for compiling C files without the need for special flags, and it also provides proper dependency tracking for these objects.
