Merge remote-tracking branch 'qatar/master'

* qatar/master:
  MS Screen 1 decoder
  aacdec: Fix popping channel layouts.
  av_gettime: support Win32 without gettimeofday()
  Use av_gettime() in various places
  Move av_gettime() to libavutil
  dct-test: use emms_c() from libavutil instead of duplicating it
  mov: fix operator precedence bug
  mathematics.h: remove a couple of math defines
  Remove unnecessary inclusions of [sys/]time.h
  lavf: remove unnecessary inclusions of unistd.h
  bfin: libswscale: add const where appropriate to fix warnings
  bfin: libswscale: remove unnecessary #includes
  udp: Properly check for invalid sockets
  tcp: Check the return value from getsockopt
  network: Use av_strerror for getting error messages
  udp: Properly print error from getnameinfo
  mmst: Use AVUNERROR() to convert error codes to the right range for strerror
  network: Pass pointers of the right type to get/setsockopt/ioctlsocket on windows
  rtmp: Reduce the number of idle posts sent by sleeping 50ms
