int31 / reduce noise

[Jukka Heinonen]

This patch reduces noise (unnecessary FIXMEs) from DPMI programs.
This makes it easier to spot the real errors.




Changelog:
  Replace FIXMEs with TRACEs in those paging 
  functions that really are not supposed to do anything.
  Add simple emulation of coprocessor state functions.
