Simplify sys/compat/sys/sockio.h. No functional change intended.

- Move some definitions from sys/compat/sockio.h to compat/net/if.h.
struct oif_data in sockio.h and if_data50 are the same, so remove oif_data.
Do the same thing to oifdatareq, too.
- u_quad_t -> uint64_t. No functional change.

Don't reference ifp->if_data directly; use if_export_if_data().

branches: 1.10.2;
Remove clause 3 and 4 leftovers from TNF licenses in more sources.

Confirmed by martin@ in PR/54760.

Rather than keeping a separate mutex, condvar, and pserialize for each
module hook, we can share a common set of synchronization structures.
This cuts the amount of cacheline_aligned data for these structures by
50%.

Note that we still have a per-hook localcount, since we need to count
individual references.

Rename the MODULE_*_HOOK() macros to MODULE_HOOK_*() as briefly
discussed on irc.

NFCI intended.

Ride the earlier kernel bump - it;s getting crowded.

Merge the [pgoyette-compat] branch

Fix a bug that SIOC[GZ]IFDATA returned old ifreq structure.

Test for valid interface for ioctls that demand it.

Thanks to Robert Swindells for the patch.

provide vectors for the ifconf compat code and ifdatareq compat code.

Now they are handled by $sysarghdrextra in sys/kern/syscalls.conf.
