This adds a `TxoutType::WITNESS_V1_TAPROOT` for P2TR outputs, and permits spending
them in standardness rules. No corresponding `CTxDestination` is added for it,
as that isn't needed until we want wallet integration. The taproot validation flags
are also enabled for mempool transactions, and standardness rules are added
(stack item size limit, no annexes).
This adds a new `SigVersion::TAPSCRIPT`, makes the necessary interpreter
changes to make it implement BIP342, and uses them for leaf version 0xc0
in Taproot script path spends.
This includes key path spending and script path spending, but not the
Tapscript execution implementation (leaf 0xc0 remains unemcumbered in
this commit).
Includes constants for various aspects of the consensus rules suggested
by Jeremy Rubin.
This enables the schnorrsig module in libsecp256k1, adds the relevant types
and functions to src/pubkey, as well as in higher-level `SignatureChecker`
classes. The (verification side of the) BIP340 test vectors is also added.
This implements the new sighashing scheme from BIP341, with all relevant
whole-transaction values precomputed once and cached.
Includes changes to PrecomputedTransactionData by Pieter Wuille.
A BIP-341 signature message may commit to the scriptPubKeys and amounts
of all spent outputs (including other ones than the input being signed
for spends), so keep them available to signature hashing code.
In preparation for adding Schnorr versions of `CheckSig`, `VerifySignature`, and
`ComputeEntry`, give them an ECDSA specific name.

7eab781a145a35d0373c4ab4d237a82b4919e88d rpc: Set HTTP Content-Type in bitcoin-cli (Wladimir J. van der Laan)
Pull request description:
We don't set any `Content-Type` in the client. It is more consistent with our other JSON-RPC use to set it to `application/json`.
Note that our server doesn't enforce content types, so it doesn't make a difference in practice. But it is fairly strange HTTP behavior to not set it at all for a POST request.
This came up in #18950.

Pull request description:
This PR adds support for ZeroMQ to listen on multiple interfaces, just like the RPC server.
Currently, if you specify more than one e.g. `zmqpubhashblock` paramter, only the first one will be used. Therefore a user may be forced to listen on all interfaces (e.g. `zmqpubhashblock=0.0.0.0:28332`), which can result in an increased attack surface.
With this PR a user can specify multiple interfaces to listen on, e.g.
`-zmqpubhashblock=tcp://127.0.0.1:28332 -zmqpubhashblock=tcp://192.168.1.123:28332`.

Pull request description:
Whenever a wallet funds a transaction, the fee reason is reported to the user only if the verbose is set to true. I added an extra parameter to `CreateTransaction` function in wallet.cpp. Then I implemented the fee reason return logic in `SendMoney` in rpcwallet.cpp, followed by verbose parameter in `sendtoaddress` and `sendmany` functions. I also added a fee reason test case in walletbasic.py.

2ea62cae483b764e30f61c06d8ac65755bbd864c Improve docs about feeler connections (Gleb Naumenko)
Pull request description:
"feeler" and "test-before-evict" are two different strategies suggest in [Eclipse Attacks on Bitcoin’s Peer-to-Peer Network](https://www.usenix.org/system/files/conference/usenixsecurity15/sec15-paper-heilman.pdf). In our codebase, we use `ConnType::FEELER` to implement both.
It is confusing, up to the point that our documentation was just incorrect.
This PR:
- ~clarifies this aspect by renaming "ConnType::FEELER" to "ConnType::PROBE", meaning that this connections only probes that the node is operational, and then disconnects.~
- fixes the documentation

8a4dcda414fcf8281d8b3b79039b735c0a7d0d4c doc: Added default signet config for linearize script (gr0kchain)
Pull request description:
Updated the example-linearize.cfg file to include support for the signet chain network config which is used by the ./linearize-data.py
Problem:
Without the signet magic, genesis hash and path config, the linearize-data.py script cannot generate a bootstrap.dat file.
Example:
```
./linearize-data.py ./linearize.cfg
Read 4776 hashes
Genesis block not found in hashlist
```
Solution:
Added netmagic, genesis and input example parameters to file. Netmagic in terms of signet is derived from the signet-challenge and not static as with other networks. The provided signet magic is based on the default public signet.
Resolution
```
./linearize-hashes.py ./linearize.cfg > ./hashlist.txt
./linearize-data.py ./linearize.cfg
$ ./linearize-data.py ./linearize.cfg

9b4fa0af40cd88ed25dd77962235fbf268bdcaa7 net: Print error message if -proxy is specified without arguments (instead of continuing without proxy server) (practicalswift)
Pull request description:
Exit with error message if `-proxy` is specified without arguments (instead of continuing without proxy server).
Continuing without a proxy server when the end-user has specified `-proxy` may result in accidental loss of privacy. (The end-user might think he/she is using a proxy when he/she is not.)
Before this patch:
```
$ src/bitcoind -proxy
…
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -proxy set -> setting -listen=0
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -proxy set -> setting -upnp=0
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -proxy set -> setting -discover=0
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -listen=0 -> setting -listenonion=0
…
2020-09-23T00:24:33Z init message: Starting network threads...
```
`bitcoind` is now running *without* a proxy server (`GetProxy(…, …) == false`, `HaveNameProxy() == false`, etc.).
Note that the "-proxy set" log messages above which the end-user might interpret as "good, my traffic is now routed via the proxy".
After this patch:
```
$ src/bitcoind -proxy
Error: No proxy server specified. Use -proxy=<ip> or -proxy=<ip:port>.
$ echo $?
1

Pull request description:
Inspired by #15206 and #15197, this PR moves all message header verification from the message processing layer and into the network/transport layer.
In the previous PRs there is a change in behavior, where we would disconnect from peers upon a single failed checksum check. In various discussions there was concern over whether this was the right choice, and some expressed a desire to see how this would look if it was made to be a pure refactor.
For more context, see https://bitcoincore.reviews/15206.html#l-81.
This PR improves the separation between the p2p layers, helping improvements like [BIP324](https://github.com/bitcoin/bitcoin/pull/18242) and #18989.
