multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263
all pthread specific code is in pthread.c
to try it, run configure --enable-pthreads and ffmpeg ... -threads <num>
the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c

ppc chroma mess workaround (real bug is that the motion compensation code assumes that 2*uvlinesize == linesize and fixing this would mean a slowdown)

   * turns out write_packet is supposed to return 0 on success, not
     how many bytes were written.

    * gotta setup coded_frame for encoding. avcodec.h says that for decoding
      lavc is supposed to set it up as well and I don't think I see any
      reason not to.

in the past it was startcode,string,00,7F,startcode
now it is startcode,string,stratcode
both are mpeg4 compliant, as according to the standard the userdata lasts until the next 00 00 01 (startcode prefix) but some very primitive decoders which simply skip until the first 00 byte and then expect the next valid startcode might fail with the old variant, just a theory though (didnt test if quicktime can decode it now)

- allow INTER4V macroblocks for FLV1 codec
- fixed issue in flv file format saving 8 mp3 frames per packet instead of 1
- fixed crasher in flv file format involving mp3 buffer handling
- added FLV1 codec support for swf file format (FlashPlayer6 or above
required) and made it default
- fixed broken mp3 support in swf file format
