and to clean up disabling newlib reentrancy support. This dropped 17K
from the minimum.exe for sparc/sis and arm/rtl22xx_t now has a 15K

* libcsupport/include/rtems/libcsupport.h, libcsupport/src/newlibc.c,
libcsupport/src/no_libc.c, libcsupport/src/unixlibc.c: Eliminate
vestiges of ticks_per_timeslice controlling newlib reentrancy. The
parameter was ignored in libc_init().
reduce size of data area.
IMFS: Fixed creation of symbolic links to avoid a compiler warning.
DOSFS: Use LibBlock instead of read() to read the boot record.
* libcsupport/Makefile.am, libcsupport/preinstall.am,
libcsupport/include/rtems/termiostypes.h: Move termios helper
routines from libchip to libcsupport. Add routine which makes it easy
for a termios device driver to inform termios of its default baud
rate. This avoids inconsistencies in later termios settings changes.

as helper and as exposed nmemalign variant with few restrictions.
Also turn on compilation of _Heap_Walk but make forced calls to it
conditionally compiled. This should allow more flexibility to the
user as to run-time checking of the heap.

the SPARC.

one function per file. Also split out statistics into a separate file
which can be plugged in dynamically. Right now, it is always in. I
suspect that splitting the file removed more code than leaving
statistics in. I tinkered with malloc information command in the
shell. I resurrected the malloc arena code as malloc boundary. This
code is now compiled all the time even though it does not appear to
work.

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.

* include/rtems/libio.h: Internally use a union of an unsigned64

The h8300 seemed to be impossible to remove warnings otherwise.
Eventually the structure definition of a dev_t might be better anyway.
* include/sys/ioccom.h: Added casts to remove warnings on 16 bit
targets.
* include/sys/utime.h: Removed as file is now part of the RTEMS
newlib support.
