* 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_mwdump.c, libmisc/shell/cmd_pwd.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.
