Got one tmpfs + EVFILT_VNODE bug fixed in Dragonfly in the
process.  Dealing with hdestroy implementation differences
is really making me consider khash...

Also considering using sysdefs-list output via $Config{cc}
to support sendmsg/recvmsg without needing Inline::C. `cc'
seems pretty standard across all *BSDs.

Eric Wong (5):
  kqnotify: drop EV_CLEAR (edge triggering)
  xap_helper.h: strdup keys for DragonFlyBSD hdestroy(3)
  devel/sysdefs-list: show more info regardless of OS
  t/dir_idle: dump event list on failure
  finalize DragonFlyBSD support

I'm not entirely certain how it works with the way we use
kevent.  I do know IO::KQueue has hard-coded kevent retrievals
to 1000 events so it's conceivable we'd end up missing wakeups
as we don't loop or requeue in callers.  So just rely on the
*BSD kernel to provided requeue behavior for us by using
level-triggering.

In any case, this seems to workaround t/dir_idle.t failures
on Dragonfly due to a tmpfs bug in all versions up to v6.4.

DragonFlyBSD matches OpenBSD behavior in freeing every single key on
hdestroy(3).  I suppose hdestroy(3) is neglected enough these days that
nobody cares and we'll likely introduce a small C hash table such as
khash (also used within git).

We'll show SO_ACCEPTFILTER since it's supported on three
of the BSDs we support.

Hopefully this makes it easier to diagnose portability
problems on new OSes we use.

require_bsd and require_mods(':fcntl_lock') are now
supported in TestCommon to make it easier to maintain
than a big list of regexps.

getsockopt for SO_ACCEPTFILTER seems to always succeed,
even if the retrieved struct is all zeroes.
