Yes, there is a global timer for closing flows, but all that does is
enqueue a cork message. +on-stir needs to set _pump_ timers for all
flows that might still have messages to send, which includes closing
flows.
When ames notifies us that our subscription has been kicked, we enqueue
a cork to clean up the flow. Unlike the %leave case, however, we were
not registering the cork in the queue of outstanding comms. We would
eventually get an ack, but not know what for, and erroneously inject
%poke-acks and %watch-acks.
Here we simply add a %cork entry to the queue before sending it.
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.

bitcoin: v0.0.2
bitcoin-wallet: set state as default case for handle-provider-update
%bitcoin: Implement additional RPC calls from btc-provider. %histogram, %block-headers, %tx-from-pos, %fee, %psbt are now all callable from the btc-provider agent. These actions are necessary in order to get the lightning network working within Urbit.
%bitcoin: Added %regtest to arms using the network type definition.
%bitcoin: add regtest type to network
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.
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.
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.
