Split parts of dvdata.h into dvdata.c, this ensures that things like
work_chunks_* and dv_idct_factor_* variables appear only once in the binary instead of 3 times. Saves 3264 bytes in .rodata and 312416 bytes in .bss on x86_64. Originally committed as revision 20246 to svn://svn.ffmpeg.org/ffmpeg/trunk
