network: load gossip db early
...
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.

Trying to fetch the prev tx from the network is a blocking operation with
a 10 sec timeout - we should not hang for 10 seconds if there is no network connection.

network: smarter switch_unwanted_fork_interface
...
Previously this function would not switch to a different chain if the
current chain contained the preferred block. This was not the intended
behaviour: if there is a *stronger* chain that *also* contains the
preferred block, we should jump to that.
Note that with this commit there will now always be a preferred block
(defaults to genesis). Previously, it might seem that often there was none,
but actually in practice if the user used the GUI context menu to switch
servers even once, there was one (usually genesis).
Hence, with the old code, if an attacker mined a single header which
then got reorged, auto_connect clients which were connected to the
attacker's server would never switch servers (jump chains) even
without the user explicitly configuring preference for the stale branch.

Data returned by the main server for request "server.peers.subscribe"
is of course untrusted input. Previously if it contained e.g. invalid port numbers
or IP addresses, it could kill the whole network taskgroup.
(this might have only affected master and not released versions,
which would only raise exceptions once the client actually tried to connect to an invalid host/port)

network: handle main_taskgroup dying better. passthrough CancelledError
...
Previously if a task running in the main_taskgroup raised,
main_taskgroup might have never finished as fx.run (another task running
in main_taskgroup) could not be cancelled (it was swallowing the CancelledError).
Need to be careful with catching all Exceptions or BaseExceptions,
as that might result in a coroutine not being cancellable.
Note that from python 3.8 onwards, CancelledError will inherit from BaseException
instead of Exception, so catching all Exceptions is somewhat less horrible
but this will only really matter if we raise the min py version to 3.8...
Really, all "except BaseException" lines are suspect and at least should be
considered for replacement with "except Exception".
-----
regarding fx.run not being cancellable before, and relevant lines, see:
