.s files to .S in conformance with GNU conventions. This is a
minor step along the way to supporting automake.

test were suggested by Ian Taylor <ian@airs.com> and Joel did the
hard part of putting it in aclocal and editting all the offending
Makefiles and source code which could use this feature.

Please find attached a start.s that includes a cli prior to the hlt
instruction. This ensures that external interrupts cannot restart
the system after returning to the startup code. ( According to the hlt
docs, they will! )
Also find a new timer.c. ( I forgot to update the countdowm value
in the timer when I changed the PSCLK frequency in start.s) . This
improves timer accuracy.
The raw_idt_notify messages are no longer infinite, I tested sp11 and
sp05, both which were bad, and I have seen the message print once in
one test. I think it's ok if it prints out once. In fact, I don't
think you can effectively stop it!

Please find attached the two files that have been changed relative to
980921 . The changes here are in the handling of the counter-timer used
as the basis for the rtems executive clock. For the most part, these
are housekeeping changes.
The PSCLK frequency change in start.s... was a part of several
bug-fixes. The fix improves executive clock and timer accuracy.
changes :
start.s -- All timers are disabled by the initialization routine
-- PSCLK ( used by clock and timers ) frequency changed to 1MHz
The clock_initialize routine now assumes that the PSCLK frequency is
exactly 1 MHz.
ckinit.c
Clock_isr -- removed division by 1000. Now use 'static'
variable -- clock_intial_isr_value -- to reset Clock_isrs variable.
clock_initialize -- moved counter timer initialization here. Values
used to configure the timer are totally dependent on
BSP_configuration.microseconds_per_tick ( and the PSCLK assumption).
Initializes clock_initial_isr_value used by th Clock_isr to reset
Clock_isrs.
clock_on -- no longer configures the timer, just enables it.
Since altering the number of sections in the BSP, I decided to give it a
good "once over" . The clock handling is now cleaner.

i386ex bsp up to date.
1) A 'hlt' instruction is coded in case of a return from boot_card in
start.s.

inline with the new IRQ structure.

Also removed bsp_postdriver_hook() from every bsp possible and moved
to shared version.
