Remove BSP-specific defaults for RTEMS_BSP_CLEANUP_OPTIONS to simplify
the BSP configuration and documentation. Change defaults to:
BSP_PRESS_KEY_FOR_RESET=0
BSP_RESET_BOARD_AT_EXIT=1
BSP_PRINT_EXCEPTION_CONTEXT=1

BSPs can use the bsp_fatal_extension() to provide BSP-specific fatal
error handling. There is no need for a _BSP_Fatal_error().

Due to a new rtems_panic() implementation, it is possible to replace the
PowerPC-specific BSP_panic() with rtems_panic(). Remove BSP_panic()
implementations.

Change bsp_interrupt_vector_enable() and bsp_interrupt_vector_disable()
to not return a status code. Add bsp_interrupt_assert() and use it to
validate the vector number in the vector enable/disable implementations.

This was done by the following script run from libbsp:
find * -name bsp.h | xargs -e grep -l "#ifndef.*_BSP_H" | while read b
do
echo $b
cpu=`echo $b | cut -d'/' -f1 | tr '[:lower:]' '[:upper:]' `
bsp=`echo $b | cut -d'/' -f2 | tr '[:lower:]' '[:upper:]' `
g="LIBBSP_${cpu}_${bsp}_BSP_H"
# echo $g
sed -e "s/ifndef _BSP_H/ifndef ${g}/" \
-e "s/define _BSP_H/define ${g}/" \
-i $b
done

The file console-polled.h provides the prototypes for the three
required methods when implementing a single port polled console
driver. This paradigm is common on simulators and simple hardware.
+ Updated the BSPs Makefile.am to make console-polled.h available.
+ Regenerated the BSPs preinstall.sm.
+ Updated console support files to include <bsp/console-polled.h>.
+ Updated console support files to make printk() support method static.

With this patch the preinstall.am files are in a set order and not
dependent on now perl implements a hash.

Apparently, at some point automake output changed and these were
not updated.

Instead of SPRG0 (= special purpose register 272) use the new global
symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask.
The benefit is that it is now possible to disable interrupts without
further run-time initialization in boot_card().
At least on Freescale e500 cores this leads also to a faster execution
since the mfmsr and mfspr instruction require four cycles to complete.
The instructions to load the mask value can execute while the mfmsr is
in progress.

Add a CPU counter interface to allow access to a free-running counter.
It is useful to measure short time intervals. This can be used for
example to enable profiling of critical low-level functions.
Add two busy wait functions rtems_counter_delay_ticks() and
rtems_counter_delay_nanoseconds() implemented via the CPU counter.

This commit deletes all RTEMS ChangeLog files. These files have been abandoned
since converting to git version control. The historical data may be recovered
by checking out any commit before this one. Most of the contents of these
ChangeLog files can also be found in the git log.
Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.

Include <bsp/default-initial-extension.h> in all BSPs. Call
rtems_fatal() with RTEMS_FATAL_SOURCE_EXIT as source and the exit()
status code as fatal code in every bsp_cleanup(). Move previous
bsp_cleanup() code into bsp_fatal_extension().

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.

The clock driver used previously the bsp_clicks_per_usec value. For a
33333333Hz time base frequency this leads to a relative error of one per
cent for example due to integer truncation.
