Bug 927 - Multithreading (MT) issues libav/ffmpeg

FFMPEG Natives:

  - Move 'mutex_avcodec_openclose' to local static and initialize at initSymbols0

  - setStream0:
    - Add another locked mutex block around:
       - [ sp_avformat_open_input .. sp_avformat_find_stream_info ]

  This solves the issue of:

    [NULL @ 0x89d20c60] insufficient thread locking around avcodec_open/close()
