2007-12-10 Joel Sherrill <joel.sherrill@oarcorp.com>

	* ChangeLog, preinstall.am, libmisc/Makefile.am, libmisc/shell/cmds.c,
	libmisc/shell/shell.c, libmisc/shell/shell.h: Split shell commands
	into multiple files and add initial stages of command configuration.
	This seems to work but the monitor commands need to be integrated
	this way and the ability to configure user commands needs to be
	tested.
	* libmisc/shell/cat_file.c, libmisc/shell/cmd_alias.c,
	libmisc/shell/cmd_cat.c, libmisc/shell/cmd_cd.c,
	libmisc/shell/cmd_chdir.c, libmisc/shell/cmd_chmod.c,
	libmisc/shell/cmd_chroot.c, libmisc/shell/cmd_date.c,
	libmisc/shell/cmd_dir.c, libmisc/shell/cmd_exit.c,
	libmisc/shell/cmd_help.c, libmisc/shell/cmd_id.c,
	libmisc/shell/cmd_logoff.c, libmisc/shell/cmd_ls.c,
	libmisc/shell/cmd_mallocdump.c, libmisc/shell/cmd_mdump.c,
	libmisc/shell/cmd_medit.c, libmisc/shell/cmd_mfill.c,
	libmisc/shell/cmd_mkdir.c, libmisc/shell/cmd_mmove.c,

	libmisc/shell/cmd_rm.c, libmisc/shell/cmd_rmdir.c,
	libmisc/shell/cmd_tty.c, libmisc/shell/cmd_umask.c,
	libmisc/shell/cmd_whoami.c, libmisc/shell/internal.h,
	libmisc/shell/shellconfig.c, libmisc/shell/shellconfig.h,
	libmisc/shell/str2int.c: New files.
