This commit implements a command line script and a GUI
dialog to receive a payment using the BIP78 protocol,
by setting up an ephemeral hidden service.
It also deprecates the pre-existing inter-Joinmarket
protocol for payjoin payments, since we now have
both sending and receiving support for BIP78. Thus,
much code in Maker, Taker and client-daemon protocol
is removed, as is some documentation in docs/PAYJOIN.md.
Also the script `sendpayment.py` is altered to support
only the BIP78 variant.
The test in jmclient/test/test_payjoin now implements
BIP78 over a TCP connection, while the custom tests in
test/payjoinserver.py can support hidden service based
tests, but the latter is not included in the test suite
and may not always work (it is only for manual
investigations).
The following features of BIP78 are supported:
minfeerate
additionalfeeoutputindex - but *only* for single
change output transactions
maxadditionalfeecontribution
The receiver does not have nor request payment
output substitution.
Utxo selection is no longer sophisticated, instead
we only choose a single utxo to keep the size
increase of the transaction minimal. Thus UIH is
not addressed at the moment.
Errors returned are in line with BIP78.
Sequence numbers are checked by receiver, and
kept identical if uniform, otherwise respected.
Receiver uses transaction monitor to shut down
when the payment is seen.
The workflow is almost entirely implemented in
jmclient/payjoin.py and the command line script
is in scripts/receive-payjoin.py. The setup, including
configuration changes for Tor, are documented in
docs/PAYJOIN.md, including a user guide video linked.
Prior to this commit, if non-self broadcast was enabled
but the counterparty chosen did not broadcast, the transaction
would remain unbroadcast.
After this commit, the Taker checks, after the configured
value of TIMEOUT.unconfirm_timeout_sec (default 90s), the
Taker will broadcast the transaction.
Also amended default config comment for this function.
5c85a3d979 Log sendrawtransaction errors as warning not debug (Kristaps Kaupe)
Pull request description:
Before this change `sendrawtransaction` errors in `pushtx()` are logged as debug, not warning. But default `console_log_level` is `INFO`. This is important enough information for the user to change log level here.
Before:
```
Would you like to push to the network? (y/n):y
2020-09-09 23:54:26,199 [ERROR] Transaction broadcast failed!
```
After:
```
Would you like to push to the network? (y/n):y
2020-09-09 23:54:26,198 [WARNING] error pushing = -26 dust (code 64)
2020-09-09 23:54:26,199 [ERROR] Transaction broadcast failed!
```
Somewhat related to #600.

0e5eb2f3b1 More verbose absurd fee exception message (Kristaps Kaupe)
Pull request description:
Display both sat/vkB and sat/vB values as we already do in other places, otherwise units may cause confusion for new users, and output both absurd fee value as well as estimated fee rate. This may help in supporting other users via Telegram, IRC, etc.

Prior to this commit, users setting the POLICY config
option `tx_broadcast` to anything other than `self` would
cause a crash after the merge of #536 due to a bin/hex
conversion failure (before this merge, the tx would simply
fail to broadcast).
This commit adds a `JMTXBroadcast` AMP command so that makers
can send arbitrary transactions from daemon to client, for
broadcast via the blockchain interface. This allows the
existing code in `taker.push()` to function correctly, after
fixing the bin/hex conversion bug. Hence users can now select
`random-peer` or `not-self` and the transaction will be
broadcast as expected according to the comments, and the
WalletService will react to the broadcast just as it does
currently for self-broadcast.
Note that this change will be ineffective if the counterparties
do not support it; the transaction will simply remain un-broadcast.

Error message about missing matplotlib is only correct in case of
exception during `import matplotlib`. If there is fatal exception
later, it is some other issue and it's better display it as is. On a
RaspiBolt for me `import matplotlib.pyplot as plt` causes
"ImportError: libopenjp2.so.7: cannot open shared object file: No such file or directory".

In this commit, the jmclient.payjoin module now supports
sending payments to BIP21 URIs where the pj= parameter is
to a hidden service address.
Additionally, the test/payjoinclient and test/payjoinserver
modules are edited to support optionally testing payments to
an ephemeral hidden service.
