[BusyBox] Upcoming changes....

[Erik Andersen]

This is a bit of a RFC.  In the upcoming days I plan on making the following
changes.  Please comment now if you disapprove, otherwise these changes will
all be going forward.  And of course everyone is invited (encouraged!) to help.

1) struct BB_applet in internal.h will be getting a few new members:
	int min_args;
	int max_args;
	char* help_sting;
2) busybox_main() will now check for if the right number of options
    were passed in or not, and if needed print s suitable error msg.
3) busybox_main() will now handle "--help" and "--version".
4) busybox_main() will now define a global variable that will define
    the name of the app that was called.
5) All usage/help strings will be moved to a common file (perhaps
    helpstrings.c).  This will have the side effect of helping 
    out any future attempts at i18n.
6) All apps will migrate to using getopt for option parsing.  Those
    that need to handle long options (i.e. tar, rm, ln) will use
    getopt to match "-" and then use strcmps and needed.
7) All apps will have any now-redundant argument bounds checking
    removed.
8) All printed text strings should be removed from apps, merged
    into messages.c, and redundant strings eliminated (which will
    also help any future attempts at i18n.

Sound ok to everyone?
