7687f7873 [wallet] Support creating a blank wallet (Andrew Chow)
Pull request description:
Alternative (kind of) to #14938
This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted.
Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938.
Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty".
This is built on top of #15225 in order to fix GUI issues.

A blank wallet is a wallet that has no keys, script or watch only things.
A new wallet flag indicating that it is blank will be set when the wallet
is blank. Once it is no longer blank (a seed has been generated, keys or
scripts imported, etc), the flag will be unset.

Allows a descriptor to be imported into the wallet using `importmulti` RPC. Start and end of range can be specified for ranged descriptors. The descriptor is implicitly converted to old structures on import.
Also adds a simple test of a P2SH-P2WPKH address being imported as a descriptor. More tests to come, as well as release notes.

[
"bc1qg6ucjz7kgdedam7v5yarecy54uqw82yym06z3q"
] // part of the BIP32 test vector
```
Avoids the need for external (BIP32) libraries to derive an address. Can be used in conjunction with `scantxoutset` as a poor mans wallet. Might be useful to test more complicated future descriptors.
~To keep it as simple as possible it only supports descriptors that result in a single address, so no `combo()` and ranges.~
As discussed recently on IRC it might make sense to put this in a separate utility along with other descriptor and psbt utility functions which don't need a chain or wallet context. However I prefer to leave that to another PR.

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

Fixes a bug where private keys could be imported to wallets with private keys disabled.

Also added an belt-and-suspenders check to `AddKeyPubkeyWithDB` to have it assert that the wallet has private keys enabled.

3c3e31c3a4 [tests] Add wallet-tool test (João Barbosa)
49d2374acf [tools] Add wallet inspection and modification tool (Jonas Schnelli)
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.

Pull request description:
No one seems to use this "feature", and at any rate the behavior of relaying transactions when they violate local policy is error-prone, if we ever consider changing the ban behavior of our software from one version to the next.
Defaulting this to off means that users who use -whitelist won't be unexpectedly surprised by this interaction. If anyone is still relying on this feature, it can still be explicitly turned on.

453803adc9 [test] wallet_txn_clone: Correctly clone txin sequence (MarcoFalke)
Pull request description:
The wallet sets the locktime to the current height of our active chain. This is fine, as long as our node is connected to other nodes. However, when we fall back and get stuck at a particular height (e.g. taking the wallet offline), the same (potentially unique) locktime is used for all transactions. This makes it easier for passive observers to cluster transactions by wallet.
For reference, I visualized "locktime-reuse" with the data:
* blocks 545k-555k (both inclusive)
* locktimes<=60k
* excluding coinbase txs
