Make Copy() take a const-ref parameter. As is, the parameter is a
pointer and it is dereferenced without any checks, and there are no
crash reports as a result of that.
Also mention GetPattern() should only be called when IsPattern() returns
true.

All the callers pass in a valid colorspace. SetColorSpace() is the only
caller to CPDF_ColorSpace::GetDefaultColor(). Also adjust that method to
make it harder to use incorrectly.

Also fixes any problems with cycles between colorspaces.
Past fixes have solved problems with CPDF_DocPageData::GetColorSpace()
calling itself and CPDF_DocPageData::GetColorSpace() calling
CPDF_ColorSpace::Load() and vice versa. They have not solved
CPDF_ColorSpace::Load() calling itself.
This CL repurposes the |pVisited| set to ensure CPDF_ColorSpace::Load()
does not try to load a colorspace as a dependency of itself and
creates |pVisitedLocal| to ensure CPDF_DocPageData::GetColorSpace()
does not create a similar circular dependency not involving
CPDF_ColorSpace::Load().
