3718ae2ef8dd2559e435bf8d7f5ed5217611ce81 [tests] Don't initialize PrecomputedTransactionData in txvalidationcache tests (John Newbery)
Pull request description:
PrecomputedTransactionData is initialized inside CheckInputScripts(). No need to pre-initialize it before calling into CheckInputScripts().
Normally, I wouldn't bother, but we're making changes to `PrecomputedTransactionData` in #17977 which would break these tests without removing these constructions. Might as well get these changes out of the way here.

Pull request description:
actually (?) fix#18561
See most recent traceback https://travis-ci.org/github/bitcoin/bitcoin/jobs/674668692#L7062
I believe the reason the error is still there is that ConnectionResetError is derived from OSError:
ConnectionResetError(ConnectionError(OSError))
And IOError is an alias for OSError since python 3.3, see https://docs.python.org/3/library/exceptions.html#IOError
So fix that by renaming IOError to the alias OSError and move the less specific catch clause down a few lines.

Pull request description:
Extracted from #16944
First this PR simplifies the check when generating a change address, by dropping `CanGetAddresses` and just letting `reservedest.GetReservedDestination` do this check.
Second, when the keypool is empty, instead of immediately giving up, we create a dummy change address and pass that to coin selection. If we didn't need the change address (e.g. when spending the entire balance), then it's all good. If we did need a change address, we throw the original error.

6f8b498d186df5aa08dbb9ca8fdeab6652f1db5e fuzz: http_request workaround for libevent < 2.1.1 (Sebastian Falbesoner)
Pull request description:
The fuzz test `http_request` calls the following two internal libevent functions:
* `evhttp_parse_firstline_`
* `evhttp_parse_headers_`
Before libevent 2.1.1 however, internal functions names didn't end with an underscore (see libevent commit 8ac3c4c25b and [Changelog for 2.1.1.-alpha](https://github.com/libevent/libevent/blob/master/ChangeLog#L1830) when the change was first mentioned) hence the build fails with a linking error.
This PR adds a preprocessor workaround to the test that checks for the libevent version (via ~`_EVENT_NUMERIC_VERSION`~ `LIBEVENT_VERSION_NUMBER`) and creates wrapper functions mapping to naming scheme without underscore in case the version is older than 2.1.1.
Tested with Ubuntu Xenial 16.04.6 LTS and clang-8.

Fix it by changing the name to `output` for both the documentation and the server code. Also, add tests to prove the server understands the new name `output`.
* Unrelated to that, there have been a bunch of aliases in the server code that are not present in the source code of the documentation. Fix that by adding the alias to the source code of the documentation. Only the first alias is displayed in the rendered documentation. Also, add tests to prove the server actually understands all aliases.

When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.
This pull preempts both issues by just sorting all includes in one commit.
Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.
Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

bda84a08a0ac92dff6cadc99cf9bb8c3fadd7e13 rpc: Add documentation for deactivating settxfee (Fabian Jahr)
Pull request description:
~~Closes 18315~~
`settxfee` can be deactivated by passing 0 as the fee. That does not seem to be documented for the user so this PR adds it in the description. The return value of a simple boolean seems also too simplified given the multiple dimensions that this deactivation feature enables. I.e. it does not seem intuitive if the returned boolean shows that the call succeeded or if means that `settxfee` is active. My suggested solution is to change the return value to a JSON object that included the "active" state and the currently set fee rate.
Examples:
```
$ src/bitcoin-cli settxfee 0.0000000
{
"active": false,
"fee_rate": "0.00000000 BTC/kB"
}
$ src/bitcoin-cli settxfee 0.0001
{
"active": true,
"fee_rate": "0.00010000 BTC/kB"
}
```

1abbdac6777bc5396d17a6772c8176a354730997 wallet: Prefer full destination groups in coin selection (Fabian Jahr)
Pull request description:
Fixes#17603 (together with #17843)
In the case of destination groups of >10 outputs existing in a wallet with `avoid_reuse` enabled, the grouping algorithm is adding left-over outputs as an "incomplete" group to the list of groups even when a full group has already been added. This leads to the strange behavior that if there are >10 outputs for a destination the transaction spending from that will effectively use `len(outputs) % 10` as inputs for that transaction.
From the original PR and the code comment I understand the correct behavior should be the usage of 10 outputs. I opted for minimal changes in the current code although there maybe optimizations possible for cases with >20 outputs on a destination this sounds like too much of an edge case right now.

Before this change, the coins simulation test uses a base view of type
CCoinsViewTest, which has no relevance outside of the unittest suite. Might as

CCoinsViewDB (i.e. in-memory leveldb) at the bottom of the view structure.
This adds explicit use of CCoinsViewDB in the unittest suite.

f63dec189c3c8eee1ab2187681d5d0b2513b1b2e [REFACTOR] Initialize PrecomputedTransactionData in CheckInputScripts (Pieter Wuille)
Pull request description:
This is a single commit taken from the Schnorr/Taproot PR #17977.
Add a default constructor to `PrecomputedTransactionData`, which doesn't initialize the struct's members. Instead they're initialized inside the `CheckInputScripts()` function. This allows a later commit to add the spent UTXOs to that structure. The spent UTXOs are required for the schnorr signature hash, since it commits to the scriptPubKeys. See https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki#common-signature-message for details.
By itself, this isn't really an improvement to the code, but I think it makes sense to separate out the refactor/moveonly commits from PR #17977 so that PR is only the logical changes needed for Schnorr/Taproot.

fad4fa7e2fb95b7ced9007060ebfd0e8f181f5d8 node: Add args alias for gArgs global (MarcoFalke)
Pull request description:
There are several issues with writing to a debug log file when fuzzing:
* Disk access is slow, but fuzzing should be fast (Note: I could not verify this claim with data)
* Disks have a limited size and will eventually run out of space, but fuzzing should run continuous
Fix both issues by disabling the debug log file for fuzz tests

The build time without cache seems to be 47 minutes and with cache 46 minutes. Maybe we can save more time by not installing clcache.

Code review ACK fa176e253fb473767c61d4d8cd2d93e87d71a015, though if you have to update this again, would suggest separating txindex test cleanup and the chainstatemanager test fix in separate commits, or identifying which part of the change is the bugfix fix in the commit description. Also to clean up the txindex test it might make sense to call SyncWithValidationInterfaceQueue in the test destructor to prevent nondeterminism in other tests
