a0fc0764763329df2c4b11a4e22715ccfc0cf7d3 refactor: test/bench: dedup Build{Crediting,Spending}Transaction() (Sebastian Falbesoner)
Pull request description:
prototypes used in `src/test/script_tests.cpp`:
- `CMutableTransaction BuildCreditingTransaction(const CScript& scriptPubKey, int nValue = 0);`
- `CMutableTransaction BuildSpendingTransaction(const CScript& scriptSig, const CScriptWitness& scriptWitness, const CTransaction& txCredit);`
prototypes used in `bench/verify_script.cpp`:
- `CMutableTransaction BuildCreditingTransaction(const CScript& scriptPubKey);`
- `CMutableTransaction BuildSpendingTransaction(const CScript& scriptSig, const CMutableTransaction& txCredit);`
The more generic versions from the script tests are moved into `setup_common.cpp` and the calls are adapted accordingly in the verify_script benchmark (passing the nValue of 1 explicitely for `BuildCreditingTransaction()`, passing empty scriptWitness explicitely and converting txCredit parameter to CTransaction in `BuildSpendingTransaction()`).

cd68594dcdadc195bd2ea9394fa04edfdbdf1149 Only check the hash of transactions loaded from disk (Andrew Chow)
Pull request description:
It feels unnecessary to do a full `CheckTransaction` for every transaction saved in the wallet. It should not be possible for an invalid transaction to get into the wallet in the first place, and if there is any disk corruption, the hash check will catch it.

BuildCreditingTransaction(), passing empty scriptWitness explicitely and
converting txCredit parameter to CTransaction in BuildSpendingTransaction()).
Calling LogPrint with a category that is not enabled results in
evaluating the remaining function arguments, which may be arbitrarily
complex (and possibly expensive) expressions. Defining LogPrint as a
macro prevents this unnecessary expression evaluation.
This is a partial revert of #14209. The decision to revert is discussed
in #16688, which adds verbose logging for validation event notification.
The serialization/deserialization methods for the classes CExtKey and
CExtPubKey were only used in the BIP32 unit tests, where the relevant parts are
removed as well.
facec1c643105d0ae74b5d32cf33d593f9e82a36 wallet: Avoid showing GUI popups on RPC errors (MarcoFalke)
Pull request description:
RPC errors and warnings are shown as popups in the GUI instead of being returned to the RPC caller. For example,
```
$ ./src/bitcoin-cli loadwallet $(pwd)/./test/functional/data/wallets/high_minversion/
error code: -4
error message:
Wallet loading failed.
```
gives me a GUI popup and no reason why loading the wallet failed.
After this pull request:
```
$ ./src/bitcoin-cli loadwallet $(pwd)/./test/functional/data/wallets/high_minversion/
error code: -4
error message:
Wallet loading failed: Error loading /home/marco/workspace/btc_bitcoin_core/./test/functional/data/wallets/high_minversion/wallet.dat: Wallet requires newer version of Bitcoin Core

Pull request description:
Noticed that there wasn't a default value for the send amount. However if you put a value in or click the up and down arrows you're unable to get it blank again, so it makes sense that it has a default value. I hope this also makes it more clear that users can send less than 1 BTC if it shows the 8 decimal places

cc3b5289ef648dca30469ee4afa615a1ed5b4e04 gui: remove OpenSSL PRNG seeding (Windows, Qt only) (fanquake)
Pull request description:
This removes the code introduced in [#4399](https://github.com/bitcoin/bitcoin/pull/4399) that attempts to add additional entroy to the OpenSSL PRNG using `RAND_event()`. This is specific to bitcoin-qt running on Windows.
```
RAND_event() collects the entropy from Windows events such as mouse movements and other user interaction.
It should be called with the iMsg, wParam and lParam arguments of all messages sent to the window procedure.
It will estimate the entropy contained in the event message (if any), and add it to the PRNG.
The program can then process the messages as usual.
```
Besides BIP70, this is the last place we are directly using OpenSSL in the GUI code. All other OpenSSL usage is in [random.cpp](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp).
Note that we are still also still doing other Windows specific gathering using [RandAddSeedPerfmon](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L268) and [RAND_screen()](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L600) on top of the other generation we do.
Also note that if RAND_event returns `0` here (PRNG has **NOT** been seeded with enough data), we're just logging a single message and continuing, which also seems less than ideal.

e65e61c812df90a56e3ce4a8e76c4b746766f387 Add some general std::vector utility functions (Pieter Wuille)
Pull request description:
This is another general improvement extracted from #16800 .
Two functions are added are:
* Vector(arg1,arg2,arg3,...) constructs a vector with the specified arguments as elements. The vector's type is derived from the arguments. If some of the arguments are rvalue references, they will be moved into place rather than copied (which can't be achieved using list initialization).
* Cat(vector1,vector2) returns a concatenation of the two vectors, efficiently moving elements when relevant.
Vector generalizes (and replaces) the `Singleton` function in src/descriptor.cpp, and `Cat` replaces the function in bech32.cpp

CommitTransaction returns a bool to indicate success, but since commit
b3a74100b8 it only returns true, even if the transaction was not
successfully broadcast. This commit changes CommitTransaction() to return
void.
All dead code in `if (!CommitTransaction())` branches has been removed.

As requested by MarcoFalke in https://github.com/bitcoin/bitcoin/pull/16273#issuecomment-521332089:
This PR removes unused includes.
Please note that in contrast to #16273 I'm limiting the scope to the trivial cases of pure removals (i.e. no includes added) to make reviewing easier.
I'm seeking "Concept ACK":s for this obviously non-urgent minor cleanup.
Rationale:
* Avoids unnecessary re-compiles in case of header changes.
* Makes reasoning about code dependencies easier.
* Reduces compile-time memory usage.
* Reduces compilation time.
* Warm fuzzy feeling of being lean :-)

d7820a1250070f3640246ae497e049bee0b3516f util: Filter control characters out of log messages (Wladimir J. van der Laan)
Pull request description:
Belts and suspenders: make sure outgoing log messages don't contain potentially suspicious characters, such as terminal control codes.
This escapes control characters except newline ('\n') in C syntax. It escapes instead of removes them to still allow for troubleshooting issues where they accidentally end up in strings (it is a debug log, after all).
(more checks could be added such as UTF-8 validity and unicode code-point range checking—this is substantially more involved and would need to keep track of state between characters and even `LogPrint` calls as they could end up split up—but escape codes seem to be the most common attack vector for terminals.)

Pull request description:
fixes#17117
I understood the bug as the help string being wrong, rather than that this feature is missing and should be added. Let me know if it should be the other way around.
It is notable that if 0 is given as an argument, the fallback that is being used is the libevent default of 50 seconds, rather than `DEFAULT_HTTP_CLIENT_TIMEOUT` (900 seconds). This is not intuitive for the user. I could handle this in this PR but I am unsure which would be the better solution then: Actually adding the feature as described in the help string or falling back to `DEFAULT_HTTP_CLIENT_TIMEOUT`? Happy to hear opinions.
