Target option parsing

Hi Folks,

I've added some code to lib/libggi/display/common/parsing.inc for option
parsing by display targets.  All you need to do is setup an array of
ggi_option with each option name and default value, and call
_GGIparseoptions(), then use the results.  The fbdev target already does
this (check out display/fbdev/visual.c), and I will soon update trueemu,
palemu & monotext similiarly.

Part of the idea is to be able to specify options for each target in an
environmental variable, such as GGI_FBDEV_OPTIONS for the fbdev target,
and GGI_TRUEEMU_OPTIONS for the trueemu target.  These options are
overridable by options in the argument string itself, as in :

      export GGI_FBDEV_OPTIONS='-mouse=microsoft -joystick=ibm'
      export GGI_DISPLAY='fbdev:-mouse=logitech:/dev/fb1'

(the -mouse in GGI_DISPLAY overrides the one in GGI_FBDEV_OPTIONS).

Cheers,
