Prefer parse_number_or_die() over atoi()/atol() parsing for the options:
-pass, -top, -vc, and -qscale.

Improve input validation.

Check that the value passed for an OPT_INT option is an int, fail
otherwise.

Also remove useless assignments of 0, the priv
context is initialized to 0.

FFmpeg can generate pts and dts on its own, but only
if we enable parsing, so do that.
This fixes ticket #46.

I was using the wrong value to track the position of the parser in the
stream. For an error-free stream, the size of the frame and number of
bytes consumed will be the same, but in an error situation they can
diverge.

Also add inttypes.h #include for PRId64 macros.

This fixes the following warnings:

The warning is printed with loglevel error because the output
stream is known to be broken.
Also warn if no channel layout was provided for multichannel input.

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).

AV_CH_LAYOUT_QUAD is the only (multi-) channel layout that has the
same channel ordering for FFmpeg and alsa.

The functions will also be used for unsigned formats.
