* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
Removed all #ifdef <cpu_flavor>. All exception vectors are now
always defined.
Changed implementation of <cpu>_vector_is_valid() from 'case'
statements to table lookup.
Replaced 'ASM_VECTORS_CRITICAL' by a variable
'bsp_raw_vector_is_405_critical' which is set at run-time.
Removed PPC_MSR_EXC_BITS. The exception handling code
(libbsp/shared/vectors/vectors.S and ../irq/irq_asm.S) now
has a run-time check for these bits.
Both files are now free of #if <cpu_flavor> constructs.
* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
Qualified all exception vector symbols that are only defined
#ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
If the special flavor __ppc_generic is effective the ALL
vector symbols are available and ppc_vector_is_valid() works
for all supported CPUs (run-time check).
This is work towards a #ifdef <cpu_flavor> free libcpu and
exception framework.
* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h,
old-exception/cpu.c: define bsp_exceptions_in_RAM variable.
This is probably only used by the simulator (were else
can you install something to ROM ??).

as needed.

new-exceptions/raw_exception.c: test for non-NULL-ness before calling
'on'/'off' methods so that users don't have to provide
no-ops if they don't want this feature.

ppc403/ictrl/ictrl.c, ppc403/irq/ictrl.c: Code outside of cpukit
should use the public API for
rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
public API and directly accessing _CPU_ISR_Disable and
_CPU_ISR_Enable, they were bypassing the compiler memory barrier
directive which could lead to problems. This patch also changes the
type of the variable passed into these routines and addresses minor
style issues.
