This is an attempt to commit the changes made to Electrum-BTC to morph it into FLO, on top of the latest Electrum-BTC codebase at the time of writing. The code has become messy pulling upstream changes and its become difficult to debug issues
Not needed since aee2d8e120
And was never really working I guess (race..)
Also, during normal initial history sync, it caused the verifier to request
proofs multiple times.
this is a performance optimisation.
measurements using a large wallet with 11k txns:
syncing XPUB for the first time takes 10 seconds. leaving window open, and
syncing same XPUB again in new window takes 30 seconds. in third window,
it takes ~50 seconds. then ~70s. presumably scaling linearly.
this is due to the history_list.update_item call being CPU-heavy.
now all of them take 10 seconds.

If our guess of a txn getting confirmed at the same height in the new chain
as it was at in the old chain is incorrect, there is a race between the
verifier and the synchronizer. If the verifier wins, the exception will cause
us to disconnect.
is_mine: wallet expects get_address_index to work
imported wallets: history did not include addr keys after creation
deterministic wallets: get_addresses() should be sorted in derivation order
