Merge remote-tracking branch 'qatar/master'

* qatar/master:
  cmutils: include shellapi.h on Win32 (for CommandLineToArgvW).
  x86/timer: implement an intrinsic-based version for rdtsc (AV_READ_TIME).
  id3v2: add a mimetype for bmp pictures.
  flacdec: be less strict when parsing attached pictures.
  flacdec: don't create an attached picture stream until we have all information.
