Message:

First attempt to implement preemptive trap handlers
and switch to userspace. Preemptive traps are needed
for at least page faults, as page fault handling code
can trigger window underflow/overflow exceptions.

This commit also introduces userspace window buffer
for saving userspace register windows (just as in
sparc64).

These changes are unfinished and far from working
correctly.
