* cpu.c, cpu_asm.S, rtems/score/cpu.h: Add logic to prevent stack creep
when interrupts occur at a sufficient rate that the interrupted
thread never gets to clean its stack. This patch ensures that an
interrupted thread will not nest ISR dispatches on its stack.

* custom/gba.cfg, custom/gp32.cfg, custom/i386ex.cfg, custom/pc386.cfg,

extension instead of BSP unique ones.
* minimum/Makefile.am, minimum/init.c: Switch back to using optional
manager support. Also add use of CONFIGURE_DISABLE_NEWLIB_REENTRANCY
to demonstrate that the newlib reentrancy support is optional.

score/src/userext.c: Switch to newlib reentrancy extension being
installed in the initial set instead of using rtems_extension_create.
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.
