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.

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.

libfdk-aacdec: Make sure decoding doesn't add any extra delay in the latest version of fdk-aac
Merged-by: Michael Niedermayer <michaelni@gmx.at>
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.

Compared to existing, common opensource H264 encoders, this can be
useful since it has got a different license (BSD instead of GPL).
Performance- and qualitywise it is comparable to x264 in ultrafast
mode.
Hooking it up as an encoder in libavcodec also simplifies comparing
it against other common encoders.
This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI
changes frequently, only releases are supported.
To take advantage of the OpenH264 patent offer, the OpenH264 library
must not be redistributed, but downloaded at runtime at the end-user's
system.

This is the order that the caller uses in the rest of the file.
Variables are modified to reflect the order above too and their
initialization is merged with their declarationt. No behavioral
change.

The r10k and avrp decoders would previously store 12 bit precision
for the blue channel, which is inconsistent and probably not a
desirable behaviour.
Now the 2 unused extra bits are set to 0.
This is possibly not ideal either as RGBA1010102 format has the same
layout but stores alpha in these bits, thus explicitly setting them
to 1 might be preferable.
