Implement the ip, tcp, and udp DTrace providers. The probe definitions use dynamic translation so that their arguments match the definitions for these providers in Solaris and illumos. Thus, existing scripts for these providers should work unmodified on FreeBSD. Tested by: gnn, hiren MFC after: 1 month

Fix style issues around existing SDT probes. - Use SDT_PROBE<N>() instead of SDT_PROBE(). This has no functional effect at the moment, but will be needed for some future changes. - Don't hardcode the module component of the probe identifier. This is set automatically by the SDT framework.
