Some streams were found to have what appeared to be truncated SPS.
Their syntax seem to be valid at least until the end of the VUI, so
try that syntax if the parsing would overflow the SPS in the
conforming syntax.
Fixes ticket #3872.

After finishing parsing VPS/SPS/PPS/slice header, check remaining bits,
and if an overconsumption occurred, report invalid data.

This makes the SPS parsing a little, but barely, safer.

- Try reading the time_base information from the VPS too, not just the VUI
- Only set time_base when an SPS is activated, not when it's decoded.
- Reduce the fraction before setting it.
- Don't set anything if the fraction is invalid (because the VUI is not
present or because the encoded value is invalid).
