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

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.

Welcome to 9.99.22 !

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

NFCI intended.

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

Normalize all the compat hooks' names to the form

<subsystem>_<function>_<version>_hook

NFCI

XXX Note that although this introduces a change in the kernel-to-
XXX module interface, we are NOT bumping the kernel version number.
XXX We will bump the version number once the interface stabilizes.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Add a new AF/PF_ROUTE which is 64-bit clean which makes the routing socket
interface (and its associated sysctls) act identically for both 32 and 64 bit
programs. The old unclean one remains for backward compatibility.
