geom: Push GEOM sysinit ordering to after devctl

GEOM depends on devctl being initialized, as it uses devctl_notify,
which assumes that devctl is initialized already. However, if devctl is
not initialized yet, the devctl UMA zone is NULL, resulting in a panic.
Thus far this has worked seemingly by linker luck that lets devctl sort
before GEOM, but this is not guaranteed. Instead, enforce the ordering
by pushing GEOM to third place, explicitly ordering it after
devctl_init, which is ordered second.

Since g_raid wants to initialize after GEOM, push that to fourth place
as well.

shutdown: audit shutdown_post_sync event callbacks

Ensure they are all panic/debugger safe.

Most handlers for this event are for disk drivers/geom modules. There
are a mix of checks being used here (or not), so let's standardize on
checking the presence of the RB_NOSYNC flag.

This flag is set whenever:
1. The kernel has panicked and kern.sync_on_panic=0*
2. We reboot from within the kernel debugger (the "reset" command)
3. Userspace requested it, e.g. by 'reboot -n'

Name the functions consistently.

*This sysctl is tuned to zero by default, but its existence means that
these handlers can be executed after a panic, at the user's discretion.
IMO this use-case is implicitly understood to be risky, and we'd be
better off eliminating it altogether.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

Pass BIO_SPEEDUP through all the geom layers

While some geom layers pass unknown commands down, not all do. For the ones that
don't, pass BIO_SPEEDUP down to the providers that constittue the geom, as
applicable. No changes to vinum or virstor because I was unsure how to add this
support, and I'm also unsure how to test these. gvinum doesn't implement
BIO_FLUSH either, so it may just be poorly maintained. gvirstor is for testing
and not supportig BIO_SPEEDUP is fine.

Use g_handleattr() to reply to GEOM::candelete queries.

g_handleattr() fills out bp->bio_completed; otherwise, g_getattr()
returns an error in response to the query. This caused BIO_DELETE
support to not be propagated through stacked configurations, e.g.,
a gconcat of gmirror volumes would not handle BIO_DELETE even when
the gmirrors do. g_io_getattr() was not affected by the problem.
