Add regression test for bgo#682099
Correctly remove expired Resources

Fixes a crash in GUPnP.  In the current code, Resource objects are not
always correctly removed from the resource_browser->priv->resources
hash table when they expire.  This can lead to a crash in GUPnP when
the application tries to destroy its context manager.

Update pkg-config files to include gio
Create vapi file from introspection

The skipping of the error-domain in .metadata and the -custom.vala file
are necessary due to https://bugzilla.gnome.org/show_bug.cgi?id=670673.

They can be removed once that is fixed

Bump version
Drop Requires.Private in pkg-config files

This field is not parsed at all by pkg-config! (cf. Requires.private)
Apparently whatever is listed in it is not needed.

Make Requires private in pkg-config files

Putting stuff in Requires means applications using
this library will link against that when it might
not be needed at all because they use none of that
libraries symbols directly.

If only the cflags is needed (because public headers
includes headers from that package) they
can be private to avoid uselessly linking.
