Add SPS_EXT, SEI, and subset SPS to codes that are skipped during split.
These codes can come before the PPS and results in incomplete extradata.

Use av_mallocz_array instead of iterating and check the returned memory.
Check returned memory and cleanly exit in case of error during the loop.
Avoid a null pointer dereference for invalid data.

vorbis_parser.o is built unconditionally since 5e80fb7ff, and the
unconditionally built parts of it depend on xiph.o.

This fixes builds with --disable-everything.

The latest fdk-aac code drop (from android 5.0) changed the channel
layout enums (changing the value of existing enum constants), and
renamed the option for downmixing.

The failsafe comparison between ctype and FF_ARRAY_ELEMS(channel_counts)
can trigger warnings (-Wtautological-constant-out-of-range-compare)
when building with the old FDK AAC releases, where it can't be
out of range with the enum values used there.

The only parameters needed by the demuxers are the sample rate and sample
count, which can be trivially extracted manually, without resorting to
an avpriv function.

It is required by (at least) the ogg demuxer.

Mark the current semi-public apriv API for removal.

This is done in preparation for making it public.

Currently, the API takes an external AVCodecContext, which is used only
for extradata and logging. This change will allow to it to work without
an AVCodecContext in the following commits.

The application will destroy the underlying hardware handles when
get_format() gets called again. Also this ensures the
deinitialization takes place if the get_format callback returns an
error.

Regression from 1c80c9d7ef.

The H.264 Constrained Baseline Profile (CBP) is a subset of both the
Main Profile and the Baseline Profile. In principles, a hardware
decoder that supports either of those can decode CBP content. As it
happens, Main is supported by all VDPAU drivers, and Baseline is not.

So favor map CBP to MP for now. Hopefully in the future libvdpau will
offer an explicit choice for CBP.

This fixes bug 757.

Currently, this option is accessed through AVCodecContext.mb_threshold,
which originally controlled reusing MB data when transcoding mpeg to
mpeg. Since the libvpx meaning is completely different from the original
mpegvideo meaning, it is better to use a separate private option for
this.
