Without a connection there is no way to sync, so we can fail early and don't have to wait for the timeout

b951b0973c on startup, write config options to debug.log (Larry Ruane)
Pull request description:
When a developer is examining `debug.log` after something goes wrong, it's often useful to know the exact options the failing instance of `bitcoind` was started with. Sometimes the `debug.log` file is all that's available for the analysis. This PR logs the `bitcoin.conf` entries and command-line arguments to `debug.log` on startup.

7851f14ccf rpc: incorporate review feedback from PR 17283 (Jon Atack)
Pull request description:
This PR builds on #17283 (now merged) and is followed by #17585.
It modifies the value returned by rpc getaddressinfo `labels` to an array of label name strings and deprecates the previous behavior of returning an array of JSON hash structures containing label `name` and address `purpose` key/value pairs.
before
```
"labels": [
{
"name": "DOUBLE SPEND",
"purpose": "receive"
}
```
after
```
"labels": [
"DOUBLE SPEND"
]
```
The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=labelspurpose`.
For context, see:

- http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=labelspurpose` flag while verifying the rpc getaddressinfo help text and `labels` output.
Next steps: deprecate the rpc getaddressinfo `label` field (EDIT: done in #17585) and add support for multiple labels per address. This PR will unblock those.

5db506ba59 tests: Add option --valgrind to run nodes under valgrind in the functional tests (practicalswift)
Pull request description:
What is better than fixing bugs? Fixing entire bug classes of course! :)
Add option `--valgrind` to run the functional tests under Valgrind.
Regular functional testing under Valgrind would have caught many of the uninitialized reads we've seen historically.
Let's kill this bug class once and for all: let's never use an uninitialized value ever again. Or at least not one that would be triggered by running the functional tests! :)
My hope is that this addition will make it super-easy to run the functional tests under Valgrind and thus increase the probability of people making use of it :)
Hopefully `test/functional/test_runner.py --valgrind` will become a natural part of the pre-release QA process.
**Usage:**
```
$ test/functional/test_runner.py --help
…
--valgrind run nodes under the valgrind memory error detector:
expect at least a ~10x slowdown, valgrind 3.14 or
later required
```
**Live demo:**
First, let's re-introduce a memory bug by reverting the recent P2P uninitialized read bug fix from PR #17624 ("net: Fix an uninitialized read in ProcessMessage(…, "tx", …) when receiving a transaction we already have").
```

```
Second, let's test as normal without Valgrind:
```
$ test/functional/p2p_segwit.py -l INFO

Third, let's test with `--valgrind` and see if the test fail (as we expect) when the unitialized value is used:
```
$ test/functional/p2p_segwit.py -l INFO --valgrind

A BitcoinTestFramework child class which can be imported by an external user or
project. TestShell.setup() initiates an underlying BitcoinTestFramework object
with bitcoind subprocesses, rpc interfaces and test logging.
TestShell.shutdown() safely tears down the BitcoinTestFramework object.
This ensures TestFramework default parameters are set before setup is called. A
child class will therefore have access to defaults when overriding setup.
In order for BitcoinTestFramework to correctly restart after shutdown, the
previous logging handlers need to be removed, or else logging will continue in
the previous temp directory. "Flush" ensures buffers are emptied, and "close"
ensures file handler close logging file.
Setup and shutdown code now moved into dedicated methods. Test "success" is
added as a BitcoinTestFramework member, which can be accessed outside of main.
Argument parsing also moved into separate method and called from main.
The asyncio.new_event_loop() instance is now removed from the NetworkThread
class during shutdown. This enables a NetworkThread instance to be restarted
after being closed. The current NetworkThread class guards against an existing
new_event_loop during initialization.
The function implementing segwit v0 signature hash was originally named
SegwitVersion1SignatureHash() (presumably before segwit v0 was named
segwit v0). Rename it to SegwitV0SignatureHash().
Also rename SignatureHash() to LegacySignatureHash() for disambiguation.
Addresses #17043, affects RBF and BIP68 functional tests.
The "tx-size-small" policy rule rejects transactions with a non-witness size of
smaller than 82 bytes (see src/validation.cpp:MemPoolAccept::PreChecks(...)),
which corresponds to a transaction with 1 segwit input and 1 P2WPKH output.
Through the default address change, the created test transactions have segwit
inputs now and sending to short scriptPubKeys might violate this rule. By
bumping the dummy scriptPubKey size to 22 bytes (= the size of a P2WPKH
scriptPubKey), on all occurences the problem is solved.
The dummy scriptPubKey has the format:
21 <21-byte-long string of 'a' or 1s>
former commit messages, now squashed:
test: rbf, bip68: use constant DUMMY_P2WPKH_SCRIPT for bumped scriptPubKey
test: rbf, bip68: use constant DUMMY_P2WPKH_SCRIPT for dummy scriptPubKeys (b'a' * 35)
test: rbf, bip68: comment DUMMY_P2WPKH_SCRIPT constant, put into common (new) module
