09b4ad1568 vp9: avoid infinite loop with broken files 
With a certain fuzzed file, the parser will always return 0 consumed
bytes, which makes calling code call the parser infinitely. Return the
full packet size on error instead. (Here it would be nice if parsers
could return errors at all.)

Additionally, _if_ there's some data left, return that too, which might
help with somewhat broken but still somehow playable files.

Fixes ticket #4242.

b88e80589b vp9: fix parser return values in error case 
The parser must always set the out_size and out_data pointers. The API
seems to require it, and the common code in parser.c also relies on it.

816577716b avcodec/dvdsubdec: fix accessing dangling pointers 
dvdsub_decode() can call append_to_cached_buf() 2 times, the second time
with ctx->buf as argument. If the second append_to_cached_buf() reallocs
ctx->buf, the argument will be a pointer to the previous, freed block.
This can cause invalid reads at least with some fuzzed files - and
possibly with valid files.

Since packets can apparently not be larger than 64K (even if packets are
combined), just use a fixed size buffer. It will be allocated as part of
the DVDSubContext, and although some memory is "wasted", it's relatively
minimal by modern standards and should be acceptable.

The latest version added support for a new option for enabling
a signal level limiter, which adds some extra delay. In fdk-aac, this
is enabled by default, but disable it by default here since we'd rather
have zero-delay decoding.
