Pull request description:
During coin selection, there are various places where we need to have a feerate. We need the feerate for the transaction itself, the discard fee rate, and long term feerate. Fetching these each time we need them can lead to a race condition where two feerates that should be the same are actually different. One particular instance where this can happen is during the loop in `CreateTransactionInternal`. After inputs are chosen, the expected transaction fee is calculated using a newly fetched feerate. If `pick_new_inputs == false`, the loop will go again with the assumption that the fee for the transaction remains the same. However because the feerate is fetched again, it is possible that it actually isn't and this causes coin selection to fail.
Instead of fetching the feerate each time it is needed, we fetch them all at once at the top of `CreateTransactionInternal`, store them in `CoinSelectionParams`, and use them where needed.
While some of these fee rates probably don't need this caching, I've done it for consistency and the guarantee that they remain the same.

Instead of fetching the discard feerate for each SelectCoinsMinConf
iteration, fetch and cache it once during CreateTransaction so that it
is shared for each SelectCoinsMinConf through
coin_selection_params.m_discard_feerate.
Does not change behavior.

Pull request description:
Even after #17458, we still deal with setting fees of an `OutputGroup` and filtering the `OutputGroup` outside of the struct. We currently make all of the `OutputGroup`s in `SelectCoins` and then copy and modify them within each `SelectCoinsMinConf` scenario. This PR changes this to constructing the `OutputGroup`s within the `SelectCoinsMinConf` so that the scenario can be taken into account during the group construction. Furthermore, setting of fees and filtering for effective value is moved into `OutputGroup::Insert` itself so that we don't add undesirable outputs to an `OutputGroup` rather than deleting them afterwards.
To facilitate fee calculation and effective value filtering during `OutputGroup::Insert`, `OutputGroup` now takes the feerates in its constructor and computes the fees and effective value for each output during `Insert`.
While removing `OutputGroup`s in accordance with the `CoinEligibilityFilter` still requires creating the `OutputGroup`s first, we can do that within the function that makes them - `GroupOutput`s.

Patch from MarcoFalke <falke.marco@gmail.com> in
https://github.com/bitcoin/bitcoin/pull/19425#discussion_r526701954
Co-authored-by: MarcoFalke <falke.marco@gmail.com>
This removes a source of complexity and indirection that makes it harder to
understand path checking code. Path checks will be simplified in upcoming
commits.
There is no change in behavior in this commit other than a slightly more
descriptive error message in `loadwallet` if the default "" wallet can't be
found. (The error message is improved more in upcoming commit "wallet: Remove
path checking code from loadwallet RPC".)
Instead of AddToWallet taking a temporary CWalletTx object and then potentially
merging it with a pre-existing CWalletTx, have it take a callback so callers
can update the pre-existing CWalletTx directly.
This makes AddToWallet simpler because now it is only has to be concerned with
saving CWalletTx objects and not merging them.
This makes AddToWallet calls clearer because they can now make direct updates to
CWalletTx entries without having to make temporary objects and then worry about
how they will be merged.
This is a pure refactoring, no behavior is changing.

Pull request description:
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.

If we find a solution which has no waste, just use that. This solution
is what we would consider to be optimal, and other solutions we find
would have to also have 0 waste, so they are equivalent to the first
one with 0 waste. Thus we can optimize by just choosing the first one
with 0 waste.

Pull request description:
Currently we explicitly disable BnB when there are preset inputs selected or when the subtract fee from outputs option is enabled. This PR enables BnB for both cases.
Kind of an alternative to #17246 (implements the subtract fee from outputs part of it) and borrows a test from there too.

Changes:
* Add note about test suite naming convention
* Fix exceptions
* Add regression test
Rationale:
* Consistent naming of test suites makes programmatic test running of specific tests/subsets of tests easier
* Explicit is better than implicit

```
$ contrib/devtools/lint-tests.sh

"foo_tests". Please make sure the following test suites follow
that convention:
