Do not allocate the scheduler control structures from the workspace.
This is a preparation step for configuration of clustered/partitioned
schedulers on SMP.
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.
Rename rtems_internal_error_description() to
rtems_internal_error_text(). Rename rtems_fatal_source_description() to
rtems_fatal_source_text(). Rename rtems_status_code_description() to
rtems_status_text(). Remove previous implementation of
rtems_status_text().
Add ISR lock to chain control for proper SMP protection. Replace
rtems_chain_extract() with rtems_chain_explicit_extract() and
rtems_chain_insert() with rtems_chain_explicit_insert() on SMP
configurations. Use rtems_chain_explicit_extract() and
rtems_chain_explicit_insert() to provide SMP support.
Move implementation specific parts of extension.h and extension.inl into
new header file extensionimpl.h. The extension.h contains now only the
application visible API.
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.
In the Red-Black Tree Heap the administration data structures are not
contained in the managed memory area. This can be used for example in a
task stack allocator which protects the task stacks from access by other
tasks.

* sapi/Makefile.am, sapi/preinstall.am, sapi/include/confdefs.h,
score/Makefile.am, score/preinstall.am: Add the CBS (Constant
Bandwidth Server) scheduler. This is a complex scheduling policy
built atop of the EDF scheduler. Unlike other schedulers, this one
provides a user API and handles not only deadlines of tasks but also
claimed budget per period. The main aim of the scheduler is isolation
of tasks so that each task is guaranteed to meet all deadlines
regardless of how other tasks behave.

While implementing this, noticed that user extensions and chain code
had multiple functions in a single file which is not desirable in the
SuperCore and API portions of RTEMS, so split these into multiple
files with one function per file. Also noticed that some of user
extension code was inlined for no particular reason so moved that to
C bodies. Split executive shutdown from initialization since not
every application shuts down. Moved __fini call to executive shutdown
to be more symmetrical with where it is called at startup.
