Given ETSI EN 300 743 V1.3.1 (2006-11), 7.2.1 Display definition segment
display window parameters are given in this order XMin, XMax, YMin, YMax
if  display_window_flag is set, but here this is not the case.
As a consequence the DVB subtitles are not displayed upon some videos.

This enables a more C99-compliant implementation of printf et al.

The MinGW32 project is deprecating its old version macros.

The flag is not unconditionally added to CFLAGS either and the
programs built on the host do not get habitually fed to a debugger.

Based on eeb975f5

The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.

Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.
