Log Message:
Fix 1bpp Xservers on "whitePixel=0, blackPixel=1" VRAMs.

- Don't override pScreen->blackPixel and pScreen->whitePixel
  (set in MD server Init functions per -filpPixels option)
  on 1bpp servers in merged fbSetupScreen() (merged one
  from cfbSetupScrenn and mfbSetupScreen() in old xsrc/xfree)
- Pull mfbCreateColormap() function from old xsrc/xfree tree
  and use it on 1bpp servers

Required by forthcoming X11R7'fied ancient Xsun and XsunMono servers:

Without these fixes, mouse pointers and twm window titlebar etc. are
rendered inverted.
