Commit Message

batch payment manager:

The class TxBatcher handles the creation, broadcast and replacement
of replaceable transactions. Callers (LNWatcher, SwapManager) use
methods add_payment_output and add_sweep_info. Transactions
created by TxBatcher may combine sweeps and outgoing payments.

Transactions created by TxBatcher will have their fee bumped
automatically (this was only the case for sweeps before).

TxBatcher manages several TxBatches. TxBatches are created
dynamically when needed.

The GUI does not touch txbatcher transactions:
  - wallet.get_candidates_for_batching excludes txbatcher
    transactions
  - RBF dialogs do not work with txbatcher transactions

wallet:
  - instead of reading config variables, make_unsigned_transaction
    takes new parameters: base_tx, send_change_to_lighting

tests:
  - unit tests in test_txbatcher.py (replaces test_sswaps.py)
  - force all regtests to use MPP, so that we sweep transactions
    with several HTLCs. This forces the payment manager to aggregate
    first-stage HTLC tx inputs. second-stage are not batched for now.
