Use deferred VBI instead of immediate VBI. A deferred VBI won't be
called if the user program has interrupts disabled which makes it
easier to avoid race conditions.
Add "joystick mouse" driver and default mouse callback routine (not
using P/M graphics).
fix typo
Add drivers for ST mouse, Amiga mouse, and Atari trakball. Access
routines taken from old mouse.s.
When disabling interrupts, restore original interrupt flag afterwards.

fix some typos
Fix timer IRQ hooking for atarixl target.
Always print the mouse cursor, even if coordinates haven't changed.
This makes sure that the cursor is always visible, even if the program
has written text to the screen (only valid for non-P/M mouse callbacks).
Change display logic of mouse cursor (hide and show functions).
