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 !

fix sign-compare issues.

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.

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.

Use a MP-safe hook for the rnd_ioctl compat_50 calls.

Split compat/rndpseudo_50.c into two pieces, one for native compat and
a second piece for compat32.  Update both modules accordingly.

file rndpseudo_50.c was added on branch yamt-pagecache on 2012-04-17 00:07:14 +0000

file rndpseudo_50.c was added on branch jmcneill-usbmp on 2012-02-18 07:33:54 +0000

Add COMPAT_50 and COMPAT_NETBSD32 compatibility code for rnd(4)
ioctl commands.

Tested with "rndctl -ls" using an old 32-bit version of rndctl(8)
(built for NetBSD-5.99.56/i386) and a new 64-bit kernel
(NetBSD-5.99.59/amd64).
