reworked identity resolution and service discovery

 The discovery, which does both XRDS-based (Yadis, XRI, for XRI, using proxy)
 and HTML-based search, now returns results in opkele:idiscovery_t structure.
 It uses expat-based parser idigger_t, which itself is not exposed via any
 header files, but hidden in lib/discovery.cc, the discovery testing program is
 renamed from openid_resolve to idiscover.
