5db506ba5943868cc2c845f717508739b7f05714 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").
```
$ git diff
diff --git a/src/consensus/validation.h b/src/consensus/validation.h

const std::string &reject_reason="",
```
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

59e387705c7e55ec40400301346354fa2d0c613f test: add invalid tx templates for use in functional tests (James O'Beirne)
Pull request description:
This change adds a list of `CTransaction`-generating templates which each correspond to a specific type of invalid transaction. We then use this list to test for a wider variety of invalid tx types in `p2p_invalid_tx.py` and `feature_block.py`.
Consolidating all invalid tx types will allow us to more easily cover all tx reject cases from a variety of tests without repeating ourselves. Validation logic doesn't differ much between mempool and block acceptance, but there *is* a difference and we should be sure we're testing both comprehensively.
Right now, I've only added templates covering the tx reject types listed below but if this approach seems worthwhile I will expand the list to be fully comprehensive.

568a1d72619371a45b14a8356d3f80bd0c0efabc fix ecdsa verify in test framework (Stepan Snigirev)
Pull request description:
This PR fixes a small bug in the test framework in `verify_ecdsa` function.
`r` in ecdsa signature is modulo curve order, so if the point `R` calculated during verification has x-coordinate that is larger than the curve order, the verification will fail in the test framework but pass in libsecp256k1.
Example (all in hex):
public key: `0289d889551598a0263746c01e5882ccf9b7dc4ca5a37108482c9d80de40e0a8cf`
der signature: `3006020104020104` (r = 4, s = 4)
message: `3232323232323232323232323232323232323232323232323232323232323232`
libsecp256k1 returns `true`, test framework returns `false`.

fa69588537bc91c0aedbc89ef1760d89cbffad75 test: Make PORT_MIN in test runner configurable (MarcoFalke)
Pull request description:
This is needed when some ports in the port range are used by other processes. Note that simply assigning the ports dynamically does not work:
* We spin up several nodes per test (each node gets its own port)
* We run several tests in parallel
So to avoid nodes from different tests colliding on ports, the port assignment must be deterministic (can not be dynamic).

1111bb91f517838e5b9f778bf6b5a9c8d561e857 test: Reformat python imports to aid scripted diff (MarcoFalke)
Pull request description:
By default all test nodes are connected in a chain. However, instead of just a single connection between each pair of nodes, we end up with up to four connections for a "middle" node (two outbound, two inbound, from each side).
This is generally redundant (tx and block relay should succeed with just a single connection) and confusing. For example, test timeouts after a call to `sync_` may be racy and hard to reproduce. On top of that, the test `debug.log`s are hard to read because txs and block invs may be relayed on the same connection multiple times.
Fix this by inlining `connect_nodes_bi` in the two tests that need it, and then replace it with a single `connect_nodes` in all other tests.
Historic background:
`connect_nodes_bi` has been introduced as a (temporary?) workaround for bug #5113 and #5138, which has long been fixed in #5157 and #5662.

Pull request description:
This adds a test for BIP30 to check that duplicate txs can exist in the blockchain given the first one was completely spent when the second one is added. (Requested by ajtowns in https://github.com/bitcoin/bitcoin/pull/16333#issuecomment-508604071)
We can not add a test that a later duplicate tx overwrites a previous one, because BIP30 is always enforced on regtest. If someone feels strongly about such a test, some Bitcoin Core code would have to be modified, which can be done in a follow up pull request.
Also, add a commit to fix the BIP34 test failures reported in https://github.com/bitcoin/bitcoin/pull/14633#issue-227712540

6011c9d72d1df5c2cd09de6f85c21eb4f7eb1ba8 QA: fix rpc_setban.py race (Jonas Schnelli)
Pull request description:
The new `rpc_setban.py` test failes regularly on CIs due to a race between injecting the ban and testing the log "on the other side".
The problem is, that the test immediately after the `addnode` command on node0 checks for the `dropped (banned)` entry on node1 (without giving some time).
Adding a 2 seconds sleep seems to solve the race (I guess there is no better event-driven delay).
Example of a failed test: https://bitcoinbuilds.org/index.php?ansilog=bf743910-103f-4b54-9a97-960c471061bd.log#l2906

Pull request description:
Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.
Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.
Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.
