Change the logging message displayed when the config file can't be
parsed: include the underlying exception text, so that a user who is
attepting to edit the config manually can find and fix any errors.

Consider this trace for 4.2.0:
```
Traceback (most recent call last):
File "electrum/gui/qt/__init__.py", line 332, in start_new_window
File "electrum/gui/qt/__init__.py", line 363, in _start_wizard_to_select_or_create_wallet
File "electrum/gui/qt/installwizard.py", line 302, in select_storage
File "electrum/util.py", line 504, in get_new_wallet_name
PermissionError: [Errno 1] Operation not permitted: '/Users/admin/Documents/Peach/MS'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "electrum/gui/qt/__init__.py", line 426, in main
File "electrum/gui/qt/__init__.py", line 307, in wrapper
File "electrum/gui/qt/__init__.py", line 349, in start_new_window
File "electrum/util.py", line 504, in get_new_wallet_name
PermissionError: [Errno 1] Operation not permitted: '/Users/admin/Documents/Peach/MS'
```
Note that `get_new_wallet_name` (os.listdir) can raise OSError,
and we were calling that on the main entrypoint codepath without exception-handling.
We were also calling it in the fallback codepath without exception-handling.
i.e. the GUI errored out on every startup for affected users, and without CLI usage
it was not possible to recover.
config.mempool_fees is now [] if server claims mempool is ~empty,
and None if no valid histogram has been received from server.
(previously it used to be [] in both cases)
- print the test name before each test
- start only needed agents (alice, bob, carol)
- set settle_delay using setconfig instead of restarting daemon
- test the watchtower ctn in test_watchtower
By default, Electrum saves the last opened wallet's path as well as
recently opened wallets.
This can be damaging to plausible deniability.
Now it's possible to run Electrum with `--forgetconfig` to not
write to the config at all, which includes the wallet paths.
The few other cases that used SimpleConfig.get_instance() now
either get passed a config instance, or they try to get a reference
to something else that has a reference to a config.
(see lnsweep, qt/qrcodewidget, qt/qrtextedit)
- commands are async
- the asyncio loop is started and stopped from the main script
- the daemon's main loop runs in the main thread
- use jsonrpcserver and jsonrpcclient instead of jsonrpclib
- fix bug in lnsweep: lnwatcher transactions were indexed by prev_txid
- add test for breach remedy with unsettled htlcs
- add timeout option to lnpay, and replace DO_NOT_SETTLE with SETTLE_DELAY
so that we can read intermediate commitment tx in regtest
Calculate the effective value of buckets, and filter <0 out.
Note that the filtering is done on the buckets, not per-coin.
This should better preserve the user's privacy in certain cases.
When the user "sends Max", as before, all UTXOs are selected,
even if they are not economical to spend.
