_power_save_idle_exit() was removed long ago. All arches now just
call _sys_power_save_idle_exit() if PM is enabled.

The CP context area was before on the bottom of the stack just
after the thread descriptor. Now it is moved inside the thread
descriptor to support some kind of memory protection.

fibers/tasks are now just threads and we should not be using
struct *tcs any more.

When an IRQ is serviced, the ISR dispatcher will check for any new thread in
the ready queue and switch to it. However, if the current thread is marked as
non preemptable due to _kernel.current->base.preempt > _NON_PREEMPT_THRESHOLD
then we should not switch to another one.

1) Fatal errors now all go through _SysFatalErrorHandler. When the
simulator is used, only the death of 'essential' threads will result
in the simulator exiting; some test cases that test exceptions may
actually expect a thread to terminate abnormally.
2) The human readability of the exception errors is improved.

The a3 register was supposed to hold the _thread pointer but it seems that it
does not in all cases. Safe to restore it from _kernel structure.

This change should allow threads that do not access coprocessor to safely
overflow on the coprocessor save area without any issue.

This was a kind of optimization that save few cycles in the cost of code
duplication. However the path where we resume from interrupt withouch changing
the running thread is buggy and leads to many tests to fail. For now I'd prefer
to remove this optimization and have a working port. Later, once everything is
OK, I'll have time to optimize things.

Having duplicate code leads always to this kind of situation where a bug is
fixed in one place and not in the other. This bug of updating current thread
pointer was already fixed before in the Swap function, but not in the interrupt
handler.

The function _new_thread sets the CALLINC for _thread_entry when calling the
new thread entry point. This should be CALLINC(1) (call4) instead of previous
one CALLINC(2) (call8).
This change allows resolving a crash when starting the first thread.
