* 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.
