[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.
