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.
Fixes http://forum.videolan.org/viewtopic.php?f=14&t=89651
Also add inttypes.h #include for PRId64 macros.
This fixes the following warnings:
libavformat/xwma.c:147: warning: too many arguments for format
libavformat/xwma.c:151: warning: too many arguments for format
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).
DTX, discontinuous transmission, allows emitting frames with
comfort noise when no voice is detected in the input audio.

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.

Dynamically print the supported bitrates from the local table,
instead of using a hardcoded log message.

Include VisualOn to clarify the codec name, but remove the
actual library name from the user-friendly description.
Also mention Android, to clarify which VisualOn implementation
this refers to, since they do sell other variants of the same
code, too.

This avoids warnings of this kind, everywhere priv_class
is initialized:

This code could be executed if the demuxer reads more than one
segment before returning from av_open_input_stream.

The new function is more flexible than url_exist(), as it allows to
specify which access flags to check, and does not require an explicit
open of the checked resource.
