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.

As discussed with riastradh@

Welcome to 9.99.22 !

Sync with HEAD

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

NFCI intended.

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

make this compile again (enable #if 0 code)

Merge the [pgoyette-compat] branch

Convert the macros for setting and unsetting a hook to generate
in-line code rather than using an intermediary hook##set routine.
Hooks are set and unset only in one place, so the intermediary
routine provides no benefit.  IMHO using the macro at the point-
of-call is more readable than using it elsewhere in the code and
then calling the generated intermediary routine (for which you
won't even find its declaration or definition unless you remember
to search for the HOOK_SET macro instead).

NFC intended, will verify with a bulk build and an atf test run.

The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers

Yay - we got the ccd_ioctl_60 stuff to build!

Now we can use that as a template for cleaning up all the others.

Initial implementation of sys/kern/kern_stup.c as discussed on tech-kern

For now, we only handle the dev/ccd and NTP needs;  more to follow.

Stub-out the compat ioctl routine for now to fix compile error on
kernels with no ccd device.

XXX stub it completely for now to make it compile

XXX: don't reference the global for now so that kernels without ccd build.

remove another error decl.

Merge changes from HEAD into ccd_60.c

For all of the individual xxx_60_{init,fini} routines, don't force
them to artificially return a status;  just make them void.  This
simplifies the compat_60_{init,fini} handling of errors that remain.

remove error decl

- use the conditional from the header file
- fix compilation

Declare 'error' if needed
