* Fix exception handling so that it actually works. We can now handle

  exceptions from both kernel and user mode.
* Fix context switching so that we can switch back to a proc which we
  switched away from (we were saving the state in the wrong place).
* Implement lazy switching of the high-fp state. This needs to be looked
  at again for SMP to cope with the case of a process migrating from one
  processor to another while it has the high-fp state.
* Make setregs() work properly. I still think this should be called
  cpu_exec() or something.
* Various other minor fixes.

With this lot, we can execve() /sbin/init and we get all the way up to its
first syscall. At that point, we stop because syscall handling is not done
yet.
