only filesystem (devfs), optionally completely drop out filesystem,
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/src/newlibc.c: Removed.
* libcsupport/Makefile.am, libcsupport/src/newlibc.c: Split libc_init()
into a separate file to avoid linkage dependencies on newlibc.c which
in turn pulls in fclose() and other C library methods.
* libcsupport/src/newlibc_init.c: New file.
* libcsupport/src/_rename_r.c: Fixed return code bug. Add a check
to see if the 'to' path was a directory and removed the directory.
* libmisc/Makefile.am, libmisc/shell/shellconfig.h: Added the mv command.
* libmisc/shell/main_mv.c, libmisc/shell/pathnames-mv.h: New.

vestiges of ticks_per_timeslice controlling newlib reentrancy. The

period timing statistics. Also renamed related variables and
structure members so they are the same whether you are using
nanosecond (e.g. struct timespec) or ticks (e.g. uint32_t)
granularity. This lays the groundwork for future cleanup.
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.
* libmisc/shell/shell.c, libmisc/shell/shell.h,
libmisc/shell/shell_script.c: Add support to echo the commands to
stdout. This is useful with the -v script option to show commands
as the run. Also added support to chdir to the directory the task
invoking the script is in.
* libmisc/shell/extern-cp.h, libmisc/shell/main_cp.c,
libmisc/shell/utils-cp.c: Update tro the latest FreeBSD version.
* libcsupport/Makefile.am, libcsupport/src/fchown.c: Add fchown
support.
* libcsupport/src/printk.c: Added width and padding for %s.

strings longer than 4 chanracters.

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.

libcsupport/src/malloc_statistics_helpers.c: Make sbrk()
support pluggable and optional. This eliminates the need for
heap extend and sbrk in the minimum footprint which is ~2.5K on
the SPARC.
* sapi/include/confdefs.h: Add the following configuration points:
+ CONFIGURE_MALLOC_STATISTICS

libmisc/shell/shellconfig.h: Split malloc.c into multiple files with
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.

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.
