* rtems/score/cpu.h: Added _CPU_Initialize_vectors().
* cpu_asm.S: Modify to properly dereference _ISR_Vector_table
now that it is dynamically allocated.

routines and structures that require CPU model specific information
are now in libcpu. This required significant rework of the
score/cpu header files and the creation of multiple header files
and subdirectories in libcpu/i960.

disabled on exit to ISR Thread dispatching. This allows a
context switch to finish under high high interrupt rates.

Please take a look at this new patch. It contains a cleaner implementation
of the reset operation. These patches are against 4.0.0. But the files
did not change from the 3.6.0 release. Also, the cpu.h patch below still
applies. I.e. instead of using i960ca_PRCB, use i960_PRCB.
Explanation:
The previous patch removed the use of the reset instruction,
because it always fails. But this was due to the fact that
some of the registers were corrupted by the re-init procedure.
The new patches save and restore those registers when a re-init
is done.

minor step along the way to supporting automake.
