libmisc/stringto/stringto_template.h: Convert return type from bool
to rtems_status_code and add rtems_string_to_pointer. Perform
associated clean up and changes for return type change.
* libmisc/stringto/stringtopointer.c: New file.

libmisc/shell/main_mv.c, libmisc/shell/main_netstats.c,
libmisc/shell/main_rm.c, libmisc/shell/shell_script.c: Newlib >
1.16.0 requires __need_getopt_newlib to be defined to get visibility
on the reentrancy extensions.
* 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.
* libmisc/shell/main_cp.c, libmisc/shell/main_netstats.c,
libmisc/shell/shell_script.c: Add memset() of getopt_data to
ensure it is zeroed out each time we use getopt_r().
* libmisc/shell/shell.c: Do not echo commands if input is not a tty.
This makes the scripts behave more like UNIX scripts.
