81c54dec20 rpc: update getblocktemplate with signet rule, include signet_challenge (Anthony Towns)
Pull request description:
Adds `contrib/signet/miner` for mining signet blocks.
Adds `bitcoin-util` cli utility, with the idea being it can provide bitcoin related functionality that does not rely on the ability to access a running node. Only subcommand currently is "grind" which takes a hex-encoded header and grinds its nonce until its nBits is satisfied.
Updates `getblocktemplate` to include `signet_challenge` field, and makes `getblocktemplate` require the signet rule when invoked on the signet change. Removes connectivity and IBD checks from `getblocktemplate` when applied to a test chain (regtest, testnet, signet).

5bc04e8837 [rpc/net] Introduce addconnection to test outbounds & blockrelay (Amiti Uttarwar)
Pull request description:
The existing functional test framework uses the `addnode` RPC to spin up manual connections between bitcoind nodes. This limits our ability to add integration tests for our networking code, which often executes different code paths for different connection types.
**This PR enables creating `outbound` & `block-relay-only` P2P connections in the functional tests.** This allows us to increase our p2p test coverage, since we can now verify expectations around these connection types.
This builds out the [prototype](https://github.com/bitcoin/bitcoin/issues/14210#issuecomment-527421978) proposed by ajtowns in #14210. 🙌🏽
An overview of this branch:
- introduces a new test-only RPC function `addconnection` which initiates opening an `outbound` or `block-relay-only` connection. (conceptually similar to `addnode` but for different connection types & restricted to regtest)
- adds `test_framework` support so a mininode can open an `outbound`/`block-relay-only` connection to a `P2PInterface`/`P2PConnection`.
- updates `p2p_blocksonly` tests to create a `block-relay-only` connection & verify expectations around transaction relay.
- introduces `p2p_add_connections` test that checks the behaviors of the newly introduced `add_outbound_p2p_connection` test framework function.
With these changes, there are many more behaviors that we can add integration tests for. The blocksonly updates is just one example.
Huge props to ajtowns for conceiving the approach & providing me feedback as I've built out this branch. Also thank you to jnewbery for lots of thoughtful input along the way.

Pull request description:
With the new C++17 array deduction rules, an array encompassing all values in an enum can be specified in the same header file that specifies the enum. This is useful to avoid having to repeatedly enumerate all enum values in the code. E.g. the RPC code, but also the fuzz code.

Add a new RPC endpoint to enable opening outbound connections from
the tests. The functional test framework currently uses the addnode RPC, which
has different behavior than general outbound peers. These changes enable
creating both full-relay and block-relay-only connections. The new RPC
endpoint calls through to a newly introduced AddConnection method on
CConnman that ensures we stay within the allocated max.

bf7d6e31b1 RPC: getblock: tx fee calculation for verbosity 2 via Undo data (Elliott Jin)
Pull request description:
This change is progress towards #18771 . It adapts the fee calculation part of #16083 and addresses some feedback. The additional "verbosity level 3" features are planned for a future PR.
**Original PR description:**
> Using block undo data (like in #14802) we can now show fee information for each transaction in a block without the need for additional -txindex and/or a ton of costly lookups. For a start we'll add transaction fee information to getblock verbosity level 2. This comes at a negligible speed penalty (<1%).

30bc8fab68 net: save high-bandwidth mode states in CNodeStats (Sebastian Falbesoner)
Pull request description:
Fixes#19676, "_For every peer expose through getpeerinfo RPC whether or not we selected them as HB peers, and whether or not they selected us as HB peers._" See [BIP152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki), in particular the [protocol flow diagram](https://github.com/bitcoin/bips/raw/master/bip-0152/protocol-flow.png). The newly introduced states are changed on the following places in the code:
* on reception of a `SENDCMPCT` message with valid version, the field `m_highbandwidth_from` is changed depending on the first integer parameter in the message (1=high bandwidth, 0=low bandwidth), i.e. it just mirrors the field `CNodeState.fPreferHeaderAndIDs`.
* after adding a `SENDCMPCT` message to the send queue, the field `m_highbandwidth_to` is changed depending on how the first integer parameter is set (same as above)
Note that after receiving `VERACK`, the node also sends `SENDCMPCT`, but that is only to announce the preferred version and never selects high-bandwidth mode, hence there is no need to change the state variables there, which are initialized to `false` anyways.

Pull request description:
If the `blocksonly` mode is turned on after running with transaction
relay enabled for a while, the fee estimation will serve outdated data
to both the internal wallet and to external applications that might be
feerate-sensitive and make use of `estimatesmartfee` (for example a
Lightning Network node).
This has already caused issues (for example https://github.com/bitcoin/bitcoin/issues/16840 (C-lightning), or https://github.com/lightningnetwork/lnd/issues/2562 (LND)) and it seems prudent to fail rather than to give inaccurate values.
This fixes#16840, and closes#16890 which tried to fix the symptoms (RPC) but not the cause as mentioned by sdaftuar :
> If this is a substantial problem, then I would think we should take action to protect our own wallet users as well (rather than hide the results of what our fee estimation would do!).

### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

Create a fee_rate (sat/vB) RPC param and replace overloading the conf_target and
estimate_mode params in the following 6 RPCs with it:
- sendtoaddress
- sendmany
- send
- fundrawtransaction
- walletcreatefundedpsbt
- bumpfee
In RPC bumpfee, the previously existing fee_rate remains but the unit is changed
from BTC/kvB to sat/vB. This is a breaking change, but it should not be an
overly risky one, as the units change by a factor of 1e5 and any fees specified
in BTC/kvB after this commit will either be too low and raise an error or be 1
sat/vB and can be RBFed.
Update the test coverage for each RPC.

- adds explicit feerate test coverage for `bumpfee`, `fundrawtransaction`, `walletcreatefundedpsbt`, `send`, `sendtoaddress`, and `sendmany`
- improves a few related RPC error messages and `ParseConfirmTarget()` / error message
- fixes/improves the explicit fee rate information in the 6 RPC helps, of which 2 were also missing `conf_target` sat/B units
This provides a spec and regression coverage for the potential next step of a universal `sat/vB` feerate argument (see #19543), as well as immediate coverage and minimum fixes for 0.21.
