use getCMYKLine and getDeviceNLine in CMYK mode in case of images if they ara
available

Here a slightly modified patch for CMYK mode: I go the simplier way, just
removed the #ifdef SPLASH_CMYK for SPOT_NCOMPS instead of inserting a lot of
#ifdef's in GfxState. One reason for this way was that it was nowhere (in
GfxState) used before, even not for getDeviceN() which is also only used when
compiled with SPLASH_CMYK. Another reason is that I'm still thinking that we
should remove the SPLASH_CMYK directives at all someday.

Regarding the cache for the single getRGB: okay, I'll open a new bug someday.
First we should commit this and find a solution for bug 34053. In the meantime
I'll try to find (or create) a PDF where the cache will be a really
improvement.
