Fixes a case where multichannel bitrate isn't accurately
targetted by psy model alone, never achieving the target bitrate.
Now fixed.

When targeting the "windows store application" (metro) API subset
(or the windows phone API subset), the getenv function isn't
available. If it is unavailable, just define getenv to NULL.
The check uses check_func_headers, since the function actually
might exist in the libraries, but is hidden in the headers.
The fallback is in config.h since msvc can't do -D defines with
parameters on the command line, and it's used both within the
libraries and the frontend applications (so a libavutil internal
header wouldn't be enough).

The functions which actually drive the filter graph by pushing
frames through it need to ensure an aligned stack for SIMD functions.
This fixes a crash in YADIF filter when using a mingw build in a MSVC
application.

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

lavf/concatdec: remove invalid check for AVSEEK_FLAG_BACKWARD.
lavf: filter out AVSEEK_FLAG_BACKWARD in new API.
lavf: call the new seek API from the old.

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

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.
Fixes part of ticket #2095

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.
