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.

This is the result of a sed script which converts all uses
of @{ into a consistent form.

Add CPU port type CPU_Exception_frame and function
_CPU_Exception_frame_print().
The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh,
sparc64, and v850 use an empty default implementation of
_CPU_Exception_frame_print().
Add rtems_exception_frame and rtems_exception_frame_print().
Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal()
with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc,
and sparc for unexpected exceptions.
Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the
BSP_PRINT_EXCEPTION_CONTEXT define used in the default
bsp_fatal_extension().
Add test sptests/spfatal26.

Add and use new CPU port define CPU_SIZEOF_POINTER. It must be an
integer literal that can be used by the assembler. This value will be
used to calculate offsets of structure members. These offsets will be
used in assembler code.
The size of a pointer is part of the application binary interface (ABI)
and thus independent of the actual programming language. The compiler
will provide defines to determine the current ABI. We use these defines
to select the appropriate CPU_SIZEOF_POINTER value.
Static assertions in the new file "cpukit/score/src/percpuasm.c" will
ensure that the value of CPU_SIZEOF_POINTER is consistent with the
current compiler settings. Also the offset values used by assembler
code are verfied.

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.

print script.

* rtems/score/cpu.h: Add RTEMS_COMPILER_NO_RETURN_ATTRIBUTE to
_CPU_Context_restore() because it does not return. Telling GCC this
avoids generation of dead code.

PR 1635/cpukit
* rtems/score/cpu.h, rtems/score/types.h: Refactoring of priority
handling, to isolate the bitmap implementation of priorities in the
supercore so that priority management is a little more modular. This
change is in anticipation of scheduler implementations that can
select how they manage tracking priority levels / finding the highest
priority ready task. Note that most of the changes here are simple
renaming, to clarify the use of the bitmap-based priority management.

* rtems/score/cpu.h: Include <rtems/score/types.h> first.

encapsulates information such as thread executing, heir, idle and
dispatch needed.

CPU_ALIGNMENT but minimum for heap.

consistently return void * and take a uintptr_t argument.
