- For kernel compiled only with KDTRACE_HOOKS and not any lock debugging option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0].
[0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while. Fix this by using a protection stub, leaving sfxge driver authors the responsibility for fixing it appropriately [1].

Add a separate translator for headers passed to the TCP probes in the input path. These probes get some of the fields in host order, whereas the output probes get them in network order, so a single translator isn't enough. This workaround ensures that the problem is essentially invisble to users: none of the probe arguments or their fields have changed.

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.
