GNetworkAddress was allowing IPv6 scope ids in g_network_address_new()
/ g_network_address_parse(), but not in g_network_address_parse_uri().
Fix that.
Part of https://bugzilla.gnome.org/show_bug.cgi?id=669724
Very many testcases, some GLib tools (resource compiler, etc) and
GApplication were calling g_type_init().
Remove those uses, as they are no longer required.
https://bugzilla.gnome.org/show_bug.cgi?id=686161
(which shouldn't ever have been part of the API. Grr.)
Solaris /etc/services doesn't even have "http", which was causing
tests/network-address to fail...
