The Fatal_halt handler now have two options, either halt
as before or enter system error state to return to
debugger or simulator. The exit-code is now also
propagated to the debugger which is very useful for
testing.
The CPU_Fatal_halt handler was split up into two, since
the only the LEON3 support the CPU power down.
The LEON3 halt now uses the power-down instruction to save
CPU power. This doesn't stop a potential watch-dog timer
from expiring.

Instead of calling the system call TA instruction directly it
is better paractise to isolate the trap implementation to the
system call functions.
BSP_fatal_exit() is added.

This reduces the size of the RTEMS tests on average about 45%.

The bsp_fatal_extension() will call BSP_fatal_return().

The work areas (RTEMS work space and C program heap) will be initialized
now in a separate step and are no longer part of
rtems_initialize_data_structures(). Initialization is performed with
tables of Heap_Area entries. This allows usage of scattered memory
areas present on various small scale micro-controllers.
The sbrk() support API changes also. The bsp_sbrk_init() must now deal
with a minimum size for the first memory chunk to take the configured
work space size into account.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

If bsp_early_malloc() is called early during boot room will be
allocated after BSS END. If the function is called after boot
is will call malloc() instead. The returned memory is not freeable
and always 8-byte aligned.
If the bsp_early_malloc() isn't called the function is not
dragged in and the workspace will be unmodified in size.
