Merge remote-tracking branch 'qatar/master'

* qatar/master:
  MSS1 and MSS2: set final pixel format after common stuff has been initialised
  MSS2 decoder
  configure: handle --disable-asm before check_deps
  x86: Split inline and external assembly #ifdefs
  configure: x86: Separate inline from standalone assembler capabilities
  pktdumper: Use a custom define instead of PATH_MAX for buffers
  pktdumper: Use av_strlcpy instead of strncpy
  pktdumper: Use sizeof(variable) instead of the direct buffer length
