[NETFILTER]: nf_conntrack_sip: introduce URI and header parameter parsing helpers
Introduce URI and header parameter parsing helpers. These are needed by the conntrack helper to parse expiration values in Contact: header parameters and by the NAT helper to properly update the Via-header rport=, received= and maddr= parameters.
