Add final missing bits of CineForm HD support on Linux (via the Windows

DirectShow codec).

Required changes:

 - codecs.conf entry (of course).
 - Allow opening files with “.col” in the file name, just like “vp3” and “.fpf”
   already was allowed. (CineForm expects to be able to do this, presumably
   for some color management code.)
 - In registry.c, fake a few registry keys that the codec expects the installer
   to have written. Also, change a few magic numbers (0, 2) to the appropriate
   constants (ERROR_SUCCESS, ERROR_FILE_NOT_FOUND) where appropriate, so the code
   is easier to follow.

SMP works fine, but seemingly performs suboptimally (e.g., on my dual-core
laptop, CineForm performs better if I lie to it and tell it I have four cores).
I don't know if this is inherent in the codec, or some inefficiency in the
emulated synchronization primitives.
