The gossip db is loaded early when the network is started to save
time when the gui is locked and a wallet not yet loaded. Side effects
of the LNWallet to start peering when a channel db is loaded is
circumvented.
Enables lightning by creating a node private key and storing it in
the wallet. The gossiper is not launched at start up, only if there
are existing channels.
exceptions below are raised when running python3 with "-X dev":

It is ugly that the 'channel' callback takes a wallet I guess,
but with channel backups in one wallet, and active channels in another,
it was causing problems... (when open simultaneously)
This is too complicated and ugly because it relies on side
effects. What we should do instead is collapse transactions
in children nodes of QTreeView (see #6237)
Before this, we were subscribing to our addresses in their bip32 order,
leaking this information to servers. While this leak seems mostly harmless,
it is trivial to fix.
- Use change addresses (instead of receive) for the static_remotekey to_remote outputs,
and reserve these to greatly reduce the chance of address-reuse
- Use change addresses (instead of receive) for LN channel sweep addresses.
Note that these atm are not getting reserved.
- also, disallow deleting last address from an imported wallet (fixes#3254, fixes#4833)
- also, set LNBackups.sweep_address lazily, as during fresh wallet creation
there are no addresses in the wallet at that point yet! see trace below.
