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

This prevents inconsistencies

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.
The specification wants round(abs(x))) * sign(x) which is
equivakent to round(x)

This patch can be controversial, by assuming floats are IEEE-754 and
particular behaviour of the FPU will get in the way.
Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference).

Having a loop counter is a 7 cycle gain.
Unrolling is another 7 cycle gain.
Working in reverse scan is another 6 cycles.
