If the format probe hits end of file, do not add the error code
to the buffer position.  This is obviously wrong, and with a
small input file would cause a negative buffer overflow.

Fixes issue 1818.

This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.
