The number of dba segments is the coded value + 1.
The coupling dba offset starts at the first coupling band, not at zero.

PROFILE_ADVANCED doesn't set res_fasttx, so make that a special case
in the condition that decides which IDCT to use (and whether to read
coefficients transposed or not).

IDCT coefficients are read transposed, but simple_idct does not expect
this. Therefore, only do tranposed coefficient reading if we're not
using simple_idct.

Also add inttypes.h #include for PRId64 macros.

This fixes the following warnings:

MMX is always built. Drop the ifdefs

Simplify the fallthrough case when no accelerated functions
can be initialized.

Move x86-specific constants out of swscale.c

PPC and x86 code is split off from swscale_template.c. Lots of code is
still duplicated and should be removed later.

Again uniformize the init system to be more similar to the dsputil one.

Unset h*scale_fast in the x86 init in order to make the output
consistent with the previous status. Thanks to Josh for spotting it.

Keep only the plain C code in the main rgb2rgb.c and move the x86
specific optimizations to x86/rgb2rgb.c
Change the initialization pattern a little so some of it can be
factorized to behave more like dsputils.

The functions are already av_ prefixed and sha1 header is already provided.
Install libavutil/{aes,sha}.h

ff_get_wav_header is reading data from a WAVE file and then uses it
(without validation) to malloc a buffer. It then proceeded to read
data into the buffer, without verifying that the allocation succeeded.

To address this, change ff_get_wav_header to return an error if
allocation failed, and adapted all calling code to handle that error.

The mpegts muxer does not set the stream time base using
av_set_pts_info, but expects it to have the default value of 1/90000.
If the calling code changes stream pts before writing the header,
other muxers override the time base at that point (like mpegenc.c).

Also rename the incorrectly named enc_bitrate to enc_mode, use the
enc_bitrate variable for storing the last chosen bitrate.

This avoids continuous warning log messages if not using an
exactly matching bitrate, while still allowing changing bitrate
at any point.

Also mention Android, to clarify which VisualOn implementation

It's been deprecated only a few months ago, long after 0.6.

No decoder uses the supposed replacement, request_channel_layout, yet.

Those were moved to libavutil only recently.
