When building for Android, _GNU_SOURCE will be defined, but it doesn't
actually have the fopencookie() function, or define the
cookie_io_functions_t type.
For now just skip trying to use it if we are building for Android.
Should fix#22062.

Pull request description:
Changes `KnapsackSolver` to use effective values instead of just the nominal txout value. Since fees are taken into account during the selection itself, we finally get rid of the `CreateTransaction` loop as well as a few other things that only were only necessary because of that loop.
This should not change coin selection behavior at all (except maybe remove weird edge cases that were caused by the loop). In order to keep behavior the same, `KnapsackSolver` will select outputs with a negative effective value (as it did before).

c0385f10a133d5d8a4c296e7b7a6d75c9c4eec12 Remove -feefilter option (amadeuszpawlik)
Pull request description:
net: Remove -feefilter option, as it is debug only and isn't used in any tests. Checking this option for every peer on every iteration of the message handler is unnecessary, as described in #21545.
refactor: Move feefilter logic out into a separate `MaybeSendFeefilter(...)` function to improve readability of the already long `SendMessages(...)`. fixes #21545
The configuration option `-feefilter` has been added in 9e072a6e66efbda7d39bf61eded21d2b324323be: _"Implement "feefilter" P2P message"_
According to the [BIP133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki), turning the fee filter off was ment for:
> [...] a node [...] using prioritisetransaction to accept transactions whose actual fee rates might fall below the node's mempool min fee [in order to] disable the fee filter to make sure it is exposed to all possible txid's
`-feefilter` was subsequently set as debug only in #8150, with the motivation that the help message was too difficult to translate.

fe3d17df04decc4e856121eb311636977d60f80f net: ignore block-relay-only peers when skipping DNS seed (Anthony Towns)
Pull request description:
Since #17428 bitcoind will attempt to reconnect to two block-relay-only anchors before doing any other outbound connections. When determining whether to use DNS seeds, it will currently see these two peers and decide "we're connected to the p2p network, so no need to lookup DNS" -- but block-relay-only peers don't do address relay, so if your address book is full of invalid addresses (apart from your anchors) this behaviour will prevent you from recovering from that situation.
This patch changes it so that it only skips use of DNS seeds when there are two full-outbound peers, not just block-relay-only peers.

fafd121026c4f1e25d498983e4f88c119516552b refactor: Make CFeeRate constructor architecture-independent (MarcoFalke)
Pull request description:
Currently the constructor is architecture dependent. This is confusing for several reasons:
* It is impossible to create a transaction larger than the max value of `uint32_t`, so a 64-bit `size_t` is not needed
* Policy (and consensus) code should be arch-independent
* The current code will print spurious compile errors when compiled on 32-bit systems:
```
policy/feerate.cpp:23:22: warning: result of comparison of constant 9223372036854775807 with expression of type 'size_t' (aka 'unsigned int') is always true [-Wtautological-constant-out-of-range-compare]
assert(nBytes_ <= uint64_t(std::numeric_limits<int64_t>::max()));
```
Fix all issues by making it arch-independent. Also, fix `{}` style according to dev notes.

Pull request description:
This PR is a follow up PR to #21244. The PR attempts to move us an inch towards the [goal](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615307465) by removing `GetDataDir(net_specific)` and replacing it by `gArgs.GetDataDir(net_specific)` calls.
The approach of this PR attempts to be similar to the one chosen in "De-globalize ChainstateManager" (#20158). The goal is to pass `ArgsManager` to functions (or ideally to have `ArgsManager` as a member of a class where needed; inspiration from here: #21789) instead of having it as a global variable (i.e. `gArgs`).
**Notes:**
* First commit makes `m_cached_blocks_path` `mutable` as was suggested [here](https://github.com/bitcoin/bitcoin/pull/21244#discussion_r615274095) but not fully applied in #21244. (`m_cached_datadir_path` and `m_cached_network_datadir_path` were marked as `mutable` in #21244) This commit can be in a separate PR too.
* Other commits deal with removing of `GetDataDir(net_specific)` function.
* This was originally part of #21244 but it was [left]((https://github.com/bitcoin/bitcoin/pull/21244#pullrequestreview-633779754)) for a follow up PR.
* I think that the proposed changes show nicely where there is reliance on `gArgs` which is IMO a good thing.
If you know about a better approach how to do this, please share it here.

fa9f711c3746ca3962f15224285a453744cd45b3 Fix crash when parsing command line with -noincludeconf=0 (MarcoFalke)
Pull request description:
The error message has several issues:
* It may crash instead of cleanly shutting down, when `-noincludeconf=0` is passed
* It doesn't quote the value
* It includes an erroneous trailing `\n`
* It is redundantly mentioning `"-includeconf cannot be used from commandline;"` several times, when once should be more than sufficient
Fix all issues by:
* Replacing `get_str()` with `write()` to fix the crash and quoting issue
* Remove the `\n` and only print the first value to fix the other issues
Before:
```
$ ./src/bitcoind -noincludeconf=0

After:

Pull request description:
On `master` the only way to resize the console font is to manually move your mouse and click the resize buttons. This PR introduces convenient keyboard shortcuts to resize the console font.
The common resize shortcuts for applications are `Ctrl+=`/`Ctrl++` and `Ctrl+-`/`Ctrl+_`. This means that the resize QPushButtons need two shortcuts each, but you cannot assign multiple shortcuts to a QPushButton. See: https://doc.qt.io/qt-5/qabstractbutton.html#shortcut-prop
To get around this, we introduce a new function in `guiutil`, which connects a supplied `QKeySequence` shortcut to a `QAbstractButton`. This function can be reused in other situations where more than one shortcut is needed for a button.

Instead of hijacking the effective_feerate to use the correct value
during coin selection, have OutputGroup be aware of whether we are
subtracting the fee from the outputs and provide the correct value to
use for selection.
To do this, OutputGroup now takes CoinSelectionParams and has a new
function GetSelectionAmount().
This was originally modified to use SelectCoinsMinConf in order to test
both BnB and Knapsack at the same time. But since SelectCoins does both
now, this is no longer necessary and we can revert back to actually
testing SelectCoins.
Remove the CreateTransaction while loop. Removes variables that were
only needed because of that loop. Also renames a few variables and
moves their declarations to where they are used.
Some subtractFeeFromOutputs handling is moved to after coin selection
in order to reduce their amounts once the fee is known.
If subtracting the fee reduces the change to dust, we will also now
remove the change output
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

e2a47ce08528dfb39c0340145c6977f6afd587f6 refactor: move first run detection to client code (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)

dca8ef586c57075587e6cd44db88eaa5c4b707c7 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.
