change the treatment of the strip y coordinates which previously did
not follow the description (nor did it behave like the binary decoder
on files with absolute strip offsets).

The new code is also faster and more robust.
As for the performance:
old decoder + conversion to rgb: fps = 2618
old decoder, without converting to rgb: fps = 4012
new decoder, producing rgb: fps = 4502

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

This fix works around another work around which handles a different type
of odd Cinepak data.
Thanks to Matthew Hoops (clone2727 - gmail.com) for the sample and fix.

I am not sure these new values are correct, not am I sure
the semantics are a good idea since we do not seem to make any
use of them but they caused a lot of confusion, but this
seems to make things closer to matching the documentation.

This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.
None of these symbols should be accessed directly, so declare them as
hidden.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

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.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
