b315042c8c Remove libpostproc. 
This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

af08d9aeea lavc: add avcodec_is_open(). 
It allows to check whether an AVCodecContext is open in a documented
way. Right now the undocumented way this check is done in lavf/lavc is
by checking whether AVCodecContext.codec is NULL. However it's desirable
to be able to set AVCodecContext.codec before avcodec_open2().

8400b126ac avcodec: deprecate AVFrame.age 
This was intended as an optimisation for skipped blocks in MPEG2
P-frames and never used elsewhere.  Removing this "optimisation"
speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9).
