34400c0710 Set channel state to OPENING as soon as we receive 'funding_signed', 
instead of when the funding transaction has been broadcast, because
we have no reliable way to know when it will be broadcast.

ln gossip: don't put own channels into db; always pass them to fn calls 
Previously we would put fake chan announcement and fake outgoing chan upd
for own channels into db (to make path finding work). See Peer.add_own_channel().
Now, instead of above, we pass a "my_channels" param to the relevant ChannelDB methods.

4dc74870e1 Catch exceptions raised in LNWorker._pay_to_route 
Reset payment status if an exception is caught.
Also, do not pass status to the 'invoice_status' network callback.
This fixes #5869, #5870, #5964.

3a35f90aa0 Do not use network callback to update channel states; call LNWorker methods directly instead. 
A callback was used because a single LNWnwatcher object used to be shared for all wallets.
Since wallet now have their own LNWatcher instance, this can be simplified.

36f32651cc Define network.try_broadcasting() method. 
Use it when rebroadcasting a force-close tx,
because the channel state is already set.
