Prevents warnings because the dst and src overlap (are the same) in the
memcpy() inside the function.

Prevents using the invalid mode as an index in a static array, which
would generate invalid reads.

This prevents us from reading before the start of the buffer, and thus
prevents crashes resulting from this behaviour. Fixes bug 237.

x86-64 is guaranteed to have at least SSE2, therefore the MMX/MMX2
functions will never be used in practice.

On 64bit platforms with 32bit int, this means we won't have to sign-
extend the integer anymore.

This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.

This makes the decoder output have double the magnitude
compared to before.

The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.

Fixes invalid reads while initializing the dequant tables, which uses
the bit depth to determine the QP table size.

also use AVERROR codes for some return values instead of -1

simplifies the code and does less memmove()

vorbis_bitrate_flushpacket() does not return any packets that should not be
output in the bitstream.

libvorbis takes float input, so we can just deinterleave/reorder the input
as-is instead of also converting.

Fixes a segfault if init() fails before initializing the dsp state

- enable the options for audio encoding
- properly check for user-set maxrate
- use correct calling order in vorbis_encode_setup_managed()

ProRes codes chroma blocks in 444 mode in different order than luma blocks,
so make both decoder and encoder read/write chroma blocks in right order.

Deprecate corresponding AVCodecContext field.

It's unused.

It's currently only used as temporary storage by the mov demuxer. Make
it use a local variable instead.
