chanacceptor: adding tests for the RPCAcceptor
This commit adds the TestRPCMultipleAcceptClients test which asserts
that the RPCAcceptor correctly handles multiple Accept callers.

chanacceptor: Adding Chained and RPC acceptors
This commit introduces the chanacceptor package which is used
to determine, by a set of heuristics, which open channel messages
to accept and reject. Currently, two acceptors are implemented
via the ChannelAcceptor interface: ChainedAcceptor and RPCAcceptor.
The RPCAcceptor allows the RPC client to respond to the open channel
request, and the ChainedAcceptor allows a conjunction of acceptors
to be used.

lntest/itest: wait for on-chain balance restore
We add a wait predicate to make sure the node's on-chain balance is
restored before continuing the restore test case.

This is needed since the DLP test scenario includes several restarts of
the node, and if the node isn't done scanning for on-chain balance
before the restart happens, it would be unlocked without a recovery
window, causing funds to be left undiscovered.

htlcswitch/link: remove chan sync delay
Earlier this delay was needed to increase the likelihood that the DLP
scanario was successfully completed. Since we would risk the connection
being torn down, and the link exit, we could end up with the remote
marking the channel borked, but not finishing the force close.

With the previous set of commits, we should now trigger the force close
before we merk the channel borked, which should ensure we'll resume the
orocess on next restart/connect.

contractcourt/chain_arbitrator: mark commitment broadcasted before publish
Before publishing the close tx to the network and commit to the
StateCommitmentBroadcasted state, we mark the commitment as broadcasted
and store it to the db. This ensures it will get re-published on startup
if we go down.

htlcswitch/link: don't mark channel borked on force close scanarios
Instead of marking the channel Borked in cases where we want to force
close it, we immediately let the peer fail the link. The channel state
will instead be updated by the channel arbitrator, which will transition
to StateBroadcastCommit, marking the channel borked, then marking the
commitment tx broadcasted right before publishing the force close tx. We
do this to avoid the case where we would mark it Borked, but go down
before being able to publish the closing tx.

Storing the force close tx ensures it will be re-published on startup.

lnwallet+link: move marking channel states to link
Instead of marking the database state when processing the channel
reestablishment message, we wait for the result of this processing to
arrive in the link, and mark it accordingly in the database here.

We do this move the logic determining whether we should force close the
channel or not, and what state to mark it in the DB, to the same place,
as these need to be consistent.

peer: send channel reestablish message for borked channels
When loading active channels for a connected peer, we gather channel
sync messages for all borked channels, and send them to the peer. This
should help a peer realize that the state is irreconcible, as we have
already realized.

lnwallet/btcwallet: check publication error types, handle replacement
error

Since btcwallet will return typed errors now, we can simplify the
matching logic in order to return ErrDoubleSpend.

In case a transaction cannot be published since it did not satisfy the
requirements for a valid replacement, return ErrDoubleSpend to indicate
it was not propagated.

fundingmanager: save markedOpen before marking the channel open
This commit fixes a potential issue within the fundingmanager, where
failing to write the channel opening state could cause the channel being
marked open in the DB, but the opening state not being set. On startup
this would cause the channel state machine to not be able to resume.

We fix this by saving the channel opening state _first_. This works
because saving the opening state is idempotent, and in case a channel is
found pending at startup, it will re-register for confirmation
notifications and re-do the process.

fundingmanager: unify handling of pending and non-pending channels at startup
Since the advanceFundingState now can handle pending channels, we'll
call it for both pending and non-pending channels, just making sure that
we re-initialize the channel barriers and re-publish the funding tx fro
pending channels.

This commit defines a new method waitForTimeout, that will be used to

handled by waitForFundingWithTimeout, but we want to break that one up
in smaller parts, and waitForTimeout is the first of these.
