This this fixes one of the issues with
http://blogs.bu.edu/mhirsch/files/2012/08/Rotate180CCW-checkerboard.mj2_.zip
and at least allows to demux the file properly instead
of failing during probing.

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.

Without this, lcov sometimes misses to normalize paths that contain "/./".
Also, ignore uninteresting hits in system headers.

In the default settings, both tools produce a lot of unhelpful noise.

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.
