* libgimp/gimpcolorspace.c
* libgimp/gimpcolorspace.h: Prefixed all functions with gimp_
  to avoid namespace collisions.

Changed the License in the header to LGPL. If you don't like this,
please remove those files! (But I would like them to stay since this
moving those functions into libgimp is something that should have
happened much earlier.) Nice work, Daniel!
