It's more readable and less prone to breakage.

Ignore color_type information for setting the monoblack pixel format,
only rely on bit_depth.

In particular: fix Test_1bpp_grayscale.png from issue #172.

This may work fine for some broken encoder, and not for others.

The lowres support doesn't work correctly (crops the video), so let's remove it.

Done to keep ABI compatible. Otherwise this is just silly

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.
