glib arg parser

[Havoc Pennington <hp redhat com>]

Hi,

It would be nice if glib had an argument parser. GTK already contains
some argument parsing stuff which could be replaced with a more
general system.

Proposal: popt seems to be very nice and meet all the needs anyone has
every come up with for an argument parser. Let's do a glib-style
wrapper for the interface, then ship a copy of popt with glib,
optionally using an already-installed popt instead. popt headers would
not be installed, popt would simply be used internally for the
implementation of the glib arg parser.

Alternative proposal: do a permanent fork of popt, making it more
glib-like, and put that in glib.
