Add copies of needed internal FFmpeg files under ffmpeg_files/ MPlayer used to depend on having an FFmpeg tree available at build time to provide this code, and FFmpeg changes occasionally broke the MPlayer build as a result. Some of the relevant functionality also depends on FFmpeg library symbols that are not part of the FFmpeg API, meaning that library changes could break MPlayer after the build. Add a copy of the relevant functionality to the MPlayer tree and use that instead. The added files are: - The headers bswap.h, intreadwrite.h and x86_cpu.h from libavutil. Some MPlayer code uses the functionality defined as macros and static inline functions in these headers. - Architecture-specific internal files used by the above headers. These are in the subdirectories: x86/, arm/, bfin/, sh4/. - taglists.[ch], which provides the codec tables from libavformat/riff.c and two functions to access them from libavformat/utils.c. Most of the headers are copied from FFmpeg revision 19452 with only the include guard names changed. A "common.h" include in bswap.h was changed to "libavutil/common.h" as it should use the installed header. Taglists.c contains snippets from the relevant files with some changes like renamed identifiers.
