This was added in 9b07a2dc as an ABI hack to allow older
code built with lavf 52 to register protocols even if the size
of the URLProtocol struct was increased. Later, registering
protocols from outside of lavf was removed and this workaround
isn't needed any longer since lavf 53.

This removes an unchecked malloc and a memory leak for the cases
when this workaround actually was used - which it hasn't since
lavf 53.

$(STRIP) always expands to something, because it is one of the commands
in the BRIEF list. This renders the condition pointless.

It is private and must not be touched from outside of lavf.

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.
