Since b0c2c097, vorbis would be used if libvorbis is compiled in.

Libavformat should not make any assumptions about values returned from
other libraries. This assert is easily reachable by using a non-raw
codec id.

It was done only in check_mvset(), while mv_scale() is called also by
dist_scale().

Since 2007, the Xiph.org Foundation recommends that .ogg only be used
for Ogg Vorbis audio files.

However we only do it if we have libvorbis available because the
built in vorbis encoder is not as good.

When request_channel_layout is 0,
all substreams should be decoded.

Thanks to Michael Niedermayer for spotting.

Also fix a mismatch between the parser and
decoder when request_channel_layout is a
subset of Stereo.

When mixing 3 front channels into 2, the center channel is mixed into left and right with the center mix level, not -3dB.

Don't decode further substreams if request_channel_layout
is a subset of the current substream's channel_layout.

Before, we would only discard further substreams if
request_channel_layout matched the substream's
channel_layout extactly, thus decoding additional
channels which the caller would probably end up downmixing.

Fixes compilation with MSVC. Also does not rely on on earlier config.h
include but include it directly.

The x86 runs short on registers because numerous elements are not static.
In addition, splitting them allows more optimized code, at least for x86.

For the callable function (as opposed to the inline one):
         C  SSE  SSE2  SSE4
Win32:  47   42   29    26
Win64:  30   33   25    23
The SSE version is neither compiled nor set for ARCH_X86_64, as the
inlinable function takes over.

It is currently declared as a macro who is set to inlinable functions,
among which a Neon and a default C implementations.

Add a DSP parameter to each inline function, unused except by the
default C implementation which calls a function from the DSP context.

On an Arrandale CPU, gain for an inlined SSE2 function vs. a call:
- Win32: 29 to 26 cycles
- Win64: 25 to 23 cycles

This makes the generated assembly more internally consistent,
avoiding declaring two labels for the same function (for cases
where EXTERN_ASM is empty) and not declaring a separate unprefixed
label in other cases.

This also makes sure the .func and .type delcarations have the same
prefix. They have previously not been used on the platforms
that have prefixed symbols on arm (iOS), but gas-preprocessor
has recently started using the .func declarations for adding
.thumb_func declarations for such functions.

The original test without a forced idct is still useful since it tests
the switching of the idct algorithm/permutation on x86 with MMX. MMXext
or SSE2. Make sure the test runs only if MMX inline asm is available and
force -cpuflags to all.
Add the required bitexact flag for both tests.

Also adjust header #include order and some comments.

Currently ff_interleave_packet_per_dts() waits until it gets a frame for
each stream before outputting packets in interleaved order.

Sparse streams (i.e. streams with much fewer packets than the other
streams, like subtitles or audio with DTX) tend to add up latency and in
specific cases end up allocating a large amount of memory.

Emit the top packet from the packet_buffer if it has a time delta
larger than a specified threshold.
