gall: re-enable doff, only for old-style subs
This is sufficient to bring the normal (non-prerelease-bugged) cases
into the new world.

For the prerelease ships that ran a buggier version of the new gall
subscription logic, we note that the conditional may trigger for the
nonce=1 case where it had already triggered for their
(shouldn't-be-possible) nonce=0 case. This results in a %leave on a wire
that wasn't in use. This no-ops on the publisher side though, and the
flow gets corked right away, so this is considered harmless.

gall: use a fully-formed wire when sending %cork
In response to clog notification from remote ames, we were sending a
%cork to clean up the flow. However, the wire we were using had the /sys
prefix already stripped off. Here, we put it back in.

gall: in +ap-doff, process oldest subs first
Start by killing subscription nonce 0, then work our way up instead of
down. We enhance the printf with a "total nonces" indicator so we can
still easily see the progress being made.

gall: support %doff-ing specific apps and/or ships
This gives us more control over exactly which subscriptions get culled,

9e47490c95 gall: fix %doff handling
Previous +ap-doff kicked the agent repeatedly.  We needed to kick
it only once.  Now publisher agents clear their incoming subscription
state without the subscriber making lots of new subscriptions because
of repeated kicking.

    Merge fix to +ap-kill-down and use that pattern in +mo-doff.

    This doesn't seem to work properly, but I'm not sure why so far.

gall: in/exclude the nonce from the wire as needed
+ap-nuke was not including the nonce, but should.
+ap-handle-peers was potentially including a zero nonce.

(The latter shouldn't have been possible, but there's a bug in +load
where sub-nonce.yoke gets initialized as 0 instead of 1.)

gall: cork a subscription's ames flow on-kick
Gall tells ames to %cork flows for subscriptions it has closed.
Receiving a kick also closes a subscription, but gall wasn't issuing a
%cork in that case. We correct that here.

Inlines +mo-handle-ames-response's logic at its only callsite.

f3a60aef14 gall: don't send %cork when leaving a subscription
This is a temporary fix, and first part of the gall-request-queue-fix
release in two stages. This gives a publisher ship the ability to
understand a %cork and handle it properly, but no subscriber will
be sending %corks at this stage when leaving a subscription.

We still add a nonce to all subscription wires but it doesn't
increment it when resubscribing, allowing flows to be reused.

Tested locally with toy pub/sub agents and Group join/leaving
