0b99764459 100l, the compression field in lcl extradata must be interpreted as 
int8_t, not uint8_t to allow -1 for "no compression".
The original code worked, but only when char was signed.

56b44694bd lcldec.c: change #if CONFIG_ZLIB to #if CONFIG_ZLIB_DECODER. 
The zlib related code should not be compiled in when the decoder is disabled
and it thus will never be used, even if we have zlib available.

Allows an application to register a callback that manages mutexes
on behalf of FFmpeg.
With this callback registered FFmpeg is fully thread safe.
