Although the CreateTransaction loop currently remains, it should be
largely unused. KnapsackSolver will now account for transaction fees
when doing its selection.
In the previous commit, SelectCoinsMinConf was refactored to have some
calculations become shared for KnapsackSolver and SelectCoinsBnB. In
this commit, KnapsackSolver will now use the not_input_fees and
effective_feerate so that it include the fee for non-input things
(excluding a change output) so that the algorithm will select enough to
cover those fees. This is necessary for selecting on effective values.
Additionally, the OutputGroups
created for KnapsackSolver will actually have their effective values
calculated and set, and KnapsackSolver will do its selection on those
effective values.
Lastly, SelectCoins is modified to use the same value for preselected
inputs for BnB and KnapsackSolver. While it will still use the real
value when subtracting the fee from outputs, this behavior will be
the same regardless of the algo used for selecting additional inputs.
The fees for transaction overhead and recipient outputs are now included
in nTargetValue instead of being a separate parameter. For the coin
selection algorithms, it doesn't matter that these are separate as in
either case, the algorithm needs to select enough to cover these fees.
Note that setting nValueToSelect is changed as it now includes
not_input_fees. Without the change to how nValueToSelect is increased
for KnapsackSolver, this would result in overpaying fees. The change to
increase by the difference between nFeeRet and not_input_fees allows
this to have the same behavior as previously.
Additionally, because we assume that KnapsackSolver will always find a
solution that requires change (we assume that BnB always finds a
non-change solution), we also include the fee for the change output in
KnapsackSolver's target. As part of this, we also use the changeless
nFeeRet when iterating for KnapsackSolver. This is because we include
the change fee when doing KnapsackSolver, so nFeeRet on further
iterations won't include the change fee.
Simplifies CreateTransactionInternal without changing behavior. Removes
the pick_new_inputs variable by moving the subtract fee from amount
implementation to later in the loop to where it is possible to calculate
the fee for the transaction. This allows the fee to be subtracted from
the outputs within a single iteration, instead of calculating the fee in
the first iteration, and subtracting the fee in the second.
This also removes another scenario where a second iteration of the loop
finds a smaller input set (and thus smaller fees than the first
iteration) with no change and so a third iteration of the loop is done in order to make
a change output that contains the excess fees.
To handle these cases, we always create a change output which contains
the difference between selected input values and the recipient amounts.
Once the transaction fee is calculated, the change output is reduced (in
the normal case) or the recipient amounts are reduced (in the subtract
fee from amount case). All of this is done in a single iteration of the
loop.
Feefilter option is debug only and it isn't used in any tests, it's wasteful
to check this option for every peer on every iteration of the message handler
loop. refs #21545
489ebb7b34 wallet: make chain optional for CWallet::Create (Ivan Metlushko)

Pull request description:
This is a followup for https://github.com/bitcoin/bitcoin/pull/20365#discussion_r522265003
First part of a refactoring with overall goal to simplify `CWallet` and de-duplicate code with `wallettool`
**Rationale**: split `CWallet::Create` and create `CWallet::AttachChain`.
`CWallet::AttachChain` takes chain as first parameter on purpose. In future I suggest we can remove `chain` from `CWallet` constructor.
The second commit is based on be164f9cf89b123f03b926aa980996919924ee64 from #15719 (thanks ryanofsky)

dca8ef586c wallet: refactor: dedup sqlite PRAGMA integer reads (Sebastian Falbesoner)
Pull request description:
This refactoring PR deduplicates repeated SQLite access to PRAGMA settings. Two functions `ReadPragmaInteger(...)` (reads a single integer value via statement `PRAGMA key`) and `SetPragma(...)` (sets a key to specified value via statement `PRAGMA key = value`) are introduced for this purpose.
This should be more readable and less error-prone, e.g. in case other PRAGMA settings need to be read/set in the future or the error handling has to be adapted.

Pull request description:
While reviewing #20196, I noticed the `NetPermissionFlags` enums are frequently called as if they were scoped, yet are still global. This patch upgrades `NetPermissionFlags` to a scoped class enum and updates the enumerator naming, similarly to #19771. See https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#enum-enumerations for more info.
This change would eliminate the class of bugs like https://github.com/bitcoin/bitcoin/pull/20196#discussion_r610770148 and #21644, as only defined operations on the flags would compile.

74bf850ac4 faster HexStr => 13% faster blockToJSON (Martin Ankerl)
Pull request description:
`std::string`'s push_back is rather slow because it needs to check & update the string size. For
`HexStr` the output string size is already easily know, so we can initially create the string with
the correct size and then just assign the data.
`HexStr` is heavily usd in `blockToJSON`, so this change is a noticeable benefit. Benchmark on an i7-8700 @3.2GHz:
* 71,315,461.00 ns/op master
* 62,842,490.00 ns/op this commit
So this little change makes `blockToJSON` about ~13% faster.

CWallet::CreateWalletFromFile to CWallet:::AttachChain so it can be updated in
the next commit.
This commit is most easily reviewed with
"git diff -w --color-moved=dimmed_zebra" or by diffing CWallet:::AttachChain
