- Cleaned up some comments again
- The dirtyPages[] array overrun conditions should be really safe now

Changes made to the update routines

  that have to be blitted onto the screen (find_next_page_set() and
  find_next_page_clear() functions)
Changes made to do_handle_screen_fault()
- An unhandled address is now dealt by the default SIGSEGV handler
- Print out the address of the instruction that caused the exception

- clicking on the "close" widget of the MacOS display window rings the bell
  but doesn't actually close the window to prevent Basilisk II from being
  accidentally killed without a proper shutdown of MacOS
- replaced many #ifdef HAVE_PTHREADS constructs with LOCK/UNLOCK macros
- minor cleanups

- replaced floating-point page shift calculation by integer routine, fixing
  the VOSF problems under NetBSD/m68k
- fixed off-by-7 error in 1-bit window update routines

- added a few more emulated privileged instructions to NetBSD/m68k
- tried to make VOSF run under NetBSD/m68k, little success (shows stripes and
  sometimes crashes)

- fixed a bug in 24 bpp mode, at least when there are four bytes per pixel
- a little loop optimization when clearing the dirty pages
- changed unsigned longs with the uintptr type
- also used uintpr for the page alignment function

- fbcopy_raw now works if memcpy() is not used
  (but it seems better to use memcpy since GCC has inline equivalent)
