avconv abuses the API by accessing AVStream.parser (which is private).
Removing AVStream.reference_dts in
2ba68dd0 breaks ABI compatibility for an
old avconv using a newer lavf. Fix this by adding a dummy field until
the next bump.

Just crccheck prints a warning, crccheck+explode returns an error.

Also document this behavior.

err_recognition is supposed to trigger detecting and reporting errors,
not trying to fix them.

And use init_get_bits8 to check for integer overflows while at it.

It is by definition unreliable and causes pointless noise on valid
code.

It does not make sense in the vast majority of use cases, no currently
defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything
nontrivial, and many of those get it wrong (the "correct" range is
INT_MIN to INT_MAX so that the builtin constant "all" works).

A VUI doesn't contain anything strictly necessary for decoding.
Apparently there are many samples with truncated VUIs in the wild, this
commit should allow decoding them.
