Add some planar formats we can handle without distorting the meaning of
hi and lo.
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

It's often really helpful to know why a frame wasn't decimated (lo or
hi), and how much you exceeded the threshold by, if you're trying to
tweak the thresholds to get what you want.

mpdecimate already prints a line per input frame with -v debug, this
just makes it longer.

This fixes the default build on iOS; eventually I should come up with
a better solution for that platform.

  network: prevent SIGPIPE on OSX

See: c41e0aedMerged-by: Michael Niedermayer <michaelni@gmx.at>

OSX does not know MSG_NOSIGNAL. BSD (which OSX is based on) has got
the socket option SO_NOSIGPIPE (even if modern BSDs also support
MSG_NOSIGNAL).

OSX does not know MSG_NOSIGNAL, and provides its own non-standard
mechanism instead. I guess Apple hates standards.

This allows the user to override the directory for the installation
of the pkg-config files (from the default LIBDIR/pkgconfig).

It follows the usual behaviour of Makefiles generated by automake.

A negative sample duration is invalid according to the spec, but there
are samples that use it for the DTS calculation, e.g.:
http://files.1f0.de/samples/mp4-negative-stts-problem.mp4

These currently get out of A/V sync.

Also change the logging type to AV_LOG_WARNING, because decoding the
sample can continue.
