Avoid to divide num and den by gcd in case of a parsed expression, since
that is already done in av_d2q(), and force reduction in case of "a:b"
form, allowing to honour the max parameter.
The latter change is consistent with the a/b case, and with the
documentation.
This is done in accordance with all other libraries, which no longer access ff_log2_tab from avutil directly for shared builds, and instead obtain their own copy.
This change is required for MSVC DLL builds, as well as avoids accessing a private symbol from another library.

The image sizes needed for this overflow to happen are currently not
supported in lavc, thus this should have no effect execpt making the
code more robust in light of future changes.

Internally chroma planes have multiple of four height while allocated image
planes might be smaller if CODEC_FLAG_EMU_EDGE is set. Thus we should not
output more lines of chroma than frame can accept.
Also the decoder can be safely switched to direct rendering now.
Previously if frame decoding failed it would be
silently reported as valid frame.
The fate ref is updated because sample have
truncated last video packet.
While here return meaningful error codes.

reusing the last would use uninitialized data, this should be
impossible currently, but better to check by assert.
