COMPAT_NETBSD32 is all about running the 32-bit flavor of native
binaries on a 64-bit platform[*], as such:
- Make the logic about which "sendsig" flavor to call MI (as it is in the
  native 64-bit environment) and follow the same rules as the native 32-bit
  environment.
- Make COMPAT_NETBSD32 x COMPAT_16 work the same as it would in the
  native 32-bit environment by providing a netbsd32_sendsig_sigcontext_16_hook,
  rather than overriding the entire sendsig logic with a netbsd32_sendsig_hook.
- In netbsd32___sigaction_sigtramp(), make sure the compat_netbsd32_16
  module is loaded if the trampoline version specifies a sigcontext style
  handler, otherwise return EINVAL so that libc can try again with siginfo
  style.

[*] ...except for arm32, which uses it to mean "run 32-bit OABI binaries
from the 32-bit EABI environment".  Doing it this way was arguably a mistake,
but we are stuck with it for now, so support it by providing a machine-
dependent override for netbsd32_sendsig() that also disables the corresponding
logic in netbsd32___sigaction_sigtramp().

Fixes PR kern/56487.

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@

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

NFCI intended.

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

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.
