This this fixes one of the issues with

of failing during probing.

The functions which actually drive the filter graph by pushing
frames through it need to ensure an aligned stack for SIMD functions.

This should fix misdetection of AVS files as AviSynth scripts
when AviSynth support is enabled (Bugzilla #357).

output-example links against swscale, which depends on avutil.  In standard
configurations, by pure good luck, the libs before swscale pull in all of
swscale's dependencies and linking succeeds.  However, in some configurations
like --disable-asm this is not the case and linking fails.

Hardcode the dependency to avoid a more general Makefile refactoring.

When decoding succeeded the array is copied into the permanent one.
This prevents inconsistencies
Fixes assertion failure

The reimplementation by Libav does not prevent out of array
writes, even though it looks like it does at a quick glance.

No FFmpeg releases are affected by this

Also document that it has no effect.

If the demuxer implements read_seek2() and not read_seek(),
call avformat_seek_file() from av_seek_frame().
Allow to properly seek in formats that only implement the
new API from applications that use the old one.
Tested with mplayer and a concat script.

If no decoding error was detected, but still no audio was decoded, the
frame needs to be free'ed, or it will leak.

With the parameter --valgrind-memcheck, the configure script sets
reasonable defaults that can be overridden as explained in the
documentation.

The idea of using set_defaults is from Luca Barbato.
