This patch includes a heavy rewrite of the chapter to have a more
structured approach to this chapter. It also changes the sectioning
to have the Data Structures be a section to themselves as a peer in the
outline with each logical area of macros in confdefs.h.
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.
Adds to confdefs a way to specify rtems_resource_unlimited for classic and
posix objects using a new macro CONFIGURE_OBJECTS_UNLIMITED.
Use CONFIGURE_OBJECTS_ALLOCATION_SIZE to declare the allocation size for
extending the set of objects at runtime. Updates the unlimited sample
to demonstrate how to use the new macros. Also adds new documentation in
the C User's Manual regarding configuring with unlimited objects.

* user/conf.t: Add Simple Priority Scheduler as complement to existing
Deterministic Priority Scheduler. This scheduler serves both as an
example and as a lighter weight implementation for smaller systems.

* user/conf.t, user/schedule.t: Update documentation to reflect
refactoring of SuperCore to add Scheduler and ability for user to
configure a scheduler.
* user/conf.t: Add configuration of posix message queue file
descriptors as separate entity. Also add documentation on posix
configuration elements not previously covered.
* user/conf.t, user/region.t: Change sizes of heap/region and allocated
objects in heap to intptr_t so they can be larger than a single
allocatable object (e.g. size_t).
* user/conf.t: Add support for optionally having a unified work area.
In other words, the RTEMS Workspace and C Program Heap are the same
pool of memory.
* user/bsp.t, user/conf.t, user/task.t: Add ability for application to
configure minimum stack size. Add RTEMS_CONFIGURED_MINIMUM_STACK_SIZE
constant so user can clearly indicate they want the configured as
opposed to the recommended minimum stack size.
* started/buildc.t: Add paragraph on see CVS for latest patches.
* user/conf.t: Add CONFIGURE_MESSAGE_BUFFERS_FOR_QUEUE and example
of how to compute message CONFIGURE_MESSAGE_BUFFER_MEMORY using it.
* user/bsp.t, user/conf.t, user/init.t, user/intr.t, user/overview.t,
user/timer.t: Correct default values. Make it clear that confdefs.h
calculates the memory required for you.

Delete references to CPU Table in all forms.

cpu_supplement/mips.t, cpu_supplement/powerpc.t, cpu_supplement/sh.t,
cpu_supplement/sparc.t, cpu_supplement/tic4x.t, user/conf.t: Moved
most of the remaining CPU Table fields to the Configuration Table.
This included pretasking_hook, predriver_hook, postdriver_hook,
idle_task, do_zero_of_workspace, extra_mpci_receive_server_stack,
stack_allocate_hook, and stack_free_hook. As a side-effect of this
effort some multiprocessing code was made conditional and some style
clean up occurred.
