0f459d868d fix an undefined behavior in uint::SetHex (Kaz Wesley)
Pull request description:
Decrementing psz beyond the beginning of the string is UB, even though
the out-of-bounds pointer is never dereferenced.
I don't think any clang sanitizer covers this, so I don't see any way a test could catch the original behavior.

faa1e0fb17 qt: test: Create at most one testing setup (MarcoFalke)
Pull request description:
It is assumed that ideally only one BasicTestingSetup exists at any point in time for each process (due to use of globals).
This assumption is violated in the GUI tests, as a testing setup is created as the first step of the `main` function and then (sometimes) another one for the following test cases.
So, the gui tests create two testing setups:
* `BasicTestingSetup` in `main` (added in fa4a04a5a9)
* a testing setup for individual test cases
Avoid that by destructing the testing setup in main after creation and then move the explicit `ECC_Stop` to the only places where it is needed (before and after `apptests`).

f53a70ce95 Improve documentation of memory_cleanse() (Tim Ruffing)
cac30a436c Clean up logic in memory_cleanse() for MSVC (Tim Ruffing)
Pull request description:
When working on https://github.com/bitcoin-core/secp256k1/issues/185, I noticed that the logic in memory_cleanse(), which is supposed to clear memory securely, is weird on MSVC. While it's correct, it's at least a code smell because the code clears the memory twice on MSVC. This weirdness was introduced by #11558.
This PR fixes the logic on MSVC and also improves the docs around this function. Best reviewed in individual commits, see the commit messages for more rationale. The second commit touches only comments.

01174596e6 signrawtransactionwithkey: report error when missing redeemScript/witnessScript param (Anthony Towns)
Pull request description:
Adding support for "witnessScript" as an alternative to "redeemScript" when using "signrawtransactionwithkey" meant that the `RPCTypeCheckObj()` call in `SignTransaction` can't error out just because either parameter is missing -- it's only a problem if both are missing, which isn't a state `RPCTypeCheckObj()` tests for. This results in the regression described in #16249. This patch adds some code to test for this case and give a similar error, namely:
error code: -8

* P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they're spending segwit outputs.
This also moves some (newly) shared code to separate functions: `UpdatePSBTOutput` (an analogue to `SignPSBTInput`), `IsSegWitOutput`, and `EvalDescriptorStringOrObject` (implementing the string or object notation parsing used in `scantxoutset`).

806b0052c3 [wallet] abort when attempting to fund a transaction above maxtxfee (Sjors Provoost)
Pull request description:
`FundTransaction` calls `GetMinimumFee` which, when the fee rate is absurdly high, quietly reduces the fee to `-maxtxfee`.
Becaue an absurdly high fee rate is usually the result of a fat finger, aborting seems safer behavior.

So far, the documentation of memory_cleanse() is a verbatim copy of
the commit message in BoringSSL, where this code was originally
written. However, our code evolved since then, and the commit message
is not particularly helpful in the code but is rather of historical
interested in BoringSSL only.
This commit improves improves the comments around memory_cleanse()
and gives a better rationale for the method that we use. This commit
touches only comments.

The rationale for caching the datadir is given as
```
// This can be called during exceptions by LogPrintf(), so we cache the

Since 8c2d695c4a, the debug log location is actually cached itself in `m_file_path`.

> Enables high-DPI scaling in Qt on supported platforms (see also High DPI Displays). _Supported platforms are X11, Windows and Android._ Enabling makes Qt scale the main (device independent) coordinate system according to display scale factors provided by the operating system. This corresponds to setting the `QT_AUTO_SCREEN_SCALE_FACTOR` environment variable to 1. This attribute must be set before `QGuiApplication` is constructed. This value was added in Qt 5.6.

a49503402b Make and get the multisig redeemscript and destination in one function instead of two (Andrew Chow)
Pull request description:
`CreateMultisigRedeemscript()` is changed to `AddAndGetMultisigDestination()` so that the process of constructing the redeemScript and then getting the `CTxDestination` are done in the same function. This allows that function to see what the keys in the multisig are so that the correct address type is returned from `AddAndGetDestinationForScript()`.
This only effects the `createmultisig` and `addmultisigaddress` RPCs and does not change signing logic as #16022 does.

Instead of creating a redeemScript with CreateMultisigRedeemscript and
then getting the destination with AddAndGetDestinationForScript, do
both in the same function.
CreateMultisigRedeemscript is changed to AddAndGetMultisigDestination.
It creates the redeemScript and returns it via an output parameter. Then
it calls AddAndGetDestinationForScript to add the destination to the
keystore and get the proper destination.
This allows us to inspect the public keys in the redeemScript before creating
the destination so that the correct destination is used when uncompressed
pubkeys are in the multisig.

129a5bafd9 wallet: rename g_known_wallet_flags constant to KNOWN_WALLET_FLAGS (Karl-Johan Alm)
Pull request description:
Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.
This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.
This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.
~~Note: this builds on top of #15780.~~ (merged)

Pull request description:
Don't use global (external) symbols for symbols that are used in only one translation unit.
Before:
```
$ for SYMBOL in $(nm src/bitcoind | grep -E ' [BD] ' | c++filt | cut -f3- -d' ' | grep -v @ | grep -v : | sort | grep '[a-z]' | sort -u | grep -vE '(^_|typeinfo|vtable)'); do
REFERENCES=$(git grep -lE "([^a-zA-Z]|^)${SYMBOL}([^a-zA-Z]|\$)" -- "*.cpp" "*.h")
N_REFERENCES=$(wc -l <<< "${REFERENCES}")
if [[ ${N_REFERENCES} > 1 ]]; then
continue
fi
echo "Global symbol ${SYMBOL} is used in only one translation unit: ${REFERENCES}"
done
Global symbol g_chainstate is used in only one translation unit: src/validation.cpp
Global symbol g_ui_signals is used in only one translation unit: src/ui_interface.cpp
Global symbol instance_of_cmaincleanup is used in only one translation unit: src/validation.cpp
Global symbol instance_of_cnetcleanup is used in only one translation unit: src/net.cpp
Global symbol instance_of_cnetprocessingcleanup is used in only one translation unit: src/net_processing.cpp
Global symbol pindexBestForkBase is used in only one translation unit: src/validation.cpp
Global symbol pindexBestForkTip is used in only one translation unit: src/validation.cpp
$
```
After:
```
$ for SYMBOL in $(nm src/bitcoind | grep -E ' [BD] ' | c++filt | cut -f3- -d' ' | grep -v @ | grep -v : | sort | grep '[a-z]' | sort -u | grep -vE '(^_|typeinfo|vtable)'); do
REFERENCES=$(git grep -lE "([^a-zA-Z]|^)${SYMBOL}([^a-zA-Z]|\$)" -- "*.cpp" "*.h")
N_REFERENCES=$(wc -l <<< "${REFERENCES}")
if [[ ${N_REFERENCES} > 1 ]]; then
continue
fi
echo "Global symbol ${SYMBOL} is used in only one translation unit: ${REFERENCES}"
done
$
```
