adding a new lib for more advanced argument parsing

[Alexander Best]

hi there,

looking at applications such as geom (g_*), camcontrol, etc. makes one realise
that getopt(3) is clearly not suitable for handling such complex options.
camcontrol.c even contains a whole paragraph about why getopt(3) is considered
not appropriate to handle camcontrol's argument parsing requirements (that was
1998!).

why not do a vendor import of popt 1.16 e.g.? are there license restrictions?
or maybe some other lib...

cheers.
