gps.c: Use only one instance of the map object and window

Both show_gps_locations() and show_gps_location() have
static local variables 'map' (OSM_TYPE_GPS_MAP) and 'window',
so technically both would create their own instances of these
objects.

This patch promotes the two variables to global, so that only
one instance per type ever exists.

A memory leak that is addressed is at the flag pixbuf
allocation, which has to be freed right after the image
is added to the map:
picture = gdk_pixbuf_from_pixdata(&flag_pixbuf, TRUE, NULL);
...
gdk_pixbuf_unref(picture);

There is also a heap-lifespan memory leak at:
map = g_object_new(OSM_TYPE_GPS_MAP,...
but GLib isn't exacly happy about us unrefing it right before
exiting the GTK main loop, so no fix is provided for that
unfortunately.
