parser/uri: support for URN
- uri parser has support for URNs (e.g. urn:service:sos.fire) - t_relay does not break on RURI with URNs - PVs are set as follows: $ru= "urn:service:sos.fire" $rz= "urn" $rU= "service" $rd= "sos.fire" - refer to http://tools.ietf.org/html/draft-ietf-ecrit-framework-13#page-29 for SIP signaling requirements for SIP proxy servers. - patch by Wolfgang Kampichler, closes FS#201
