This driver was written for v1.5 before the introduction of the function
_sys_clock_final_tick_announce. At that time _sys_idle_elapsed_ticks was reset
to 0 automatically. Now that it is reset by the new function, the driver needed
to be fixed.

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.

XCC does neither define __BYTE_ORDER__ nor __ORDER_LITTLE/BIG_ENDIAN__ macros.
This resulted in field preempt of thread.base not correctly built from other
union fields prio and sched_locked, which caused wrong scheduling.

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 XCC compiler freaks out if a section name passed via
__attribute__((section)) has parenthesis in it. This happens in the
case of _MDEF_THREAD_DEFINE.
It turns out the whole mechanism of placing kernel objects in completely
unique sections is totally unnecessary. This patch is a workaround until
we can clean this up.

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.

Xtensa port uses more stack than others. This was discussed with the team and
we agreed that this can be accepted for the first beta.
We will investigate this later to see how to avoid allocating coproc registers
for the system threads in order to reduce the stack overhead. However this
will not be before the port is considered stable.
