Pull request description:
This PR adds "key origin" (master fingeprint + key path) information to what is exposed from `SigningProvider`s, allowing this information to be used by the generic PSBT code instead of having the RPC pull it directly from the wallet.
This is also a preparation to having PSBT interact with output descriptors, which can then directly expose key origin information for the scripts they generate.

Pull request description:
This removes the `#include <boost/signals2/signal.hpp>` from `util.h` (hopefully speeding up the build time and reducing the memory usage further after #13634)
The whole translation interface is replaced by a function `G_TRANSLATION_FUN` that is set to nullptr in units that don't need translation. (Thus only set in the gui)

Pull request description:
Because false is synonymous with TX_NONSTANDARD, this conveys the same
information and makes the handling explicitly based on script type,
simplifying each call site.
Prior to this change it was common for the return value to be ignored, or for the
return value and TX_NONSTANDARD to be redundantly handled.

Pull request description:
All but one call to `GetBlocksToMaturity` is testing it relative to 0
for the purposes of determining whether the coinbase tx is immature.
In such case, the value greater than 0 implies that the tx is coinbase,
so there is no need to separately test that status.
This names the concept for easy singular use.

Pull request description:
When using the `settxfee` RPC, the value is silently ignored if it is less than either than minrelaytxfee or the wallet's mintxfee. This adds an error response if that's going to happen, but still allows "settxfee 0" to deliberately default to the minimum value.

Pull request description:
1) Previously an empty input argument transaction that is marked for replaceability fails to pass the `SignalsOptInRBF` check right before funding it. Explicitly check for that condition before throwing an error.
2) The rpc call had two separate `replaceable` arguments, each of which being used in mutually exclusive places. I preserved the `options` version to retain compatability with `fundtransaction`.

Pull request description:
The current PSBT signing code can end up producing a non-segwit signature, while only the UTXO being spent is provided in the PSBT (as opposed to the entire transaction being spent). This may be used to trick a user to incorrectly decide a transaction has the semantics he intends to sign.
Fix this by refusing to sign if there is any mismatch between the provided data and what is being signed.

18dfea0dd082af18dfb02981b7ee1cd44d514388 Always create 70 byte signatures with low R values (Andrew Chow)
Pull request description:
When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.
Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.
Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.
DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

18f690ec2f7eb1b4aa51825bfed0cbfdadc93ac7 wallet: shuffle coins before grouping, where warranted (Karl-Johan Alm)
Pull request description:
Coins are randomly shuffled in coin selection to avoid unintentional privacy leaks regarding the user's coin set. For the case where a user has a lot of coins with the same destination, these will be grouped into groups of 10 *before* the shuffling.
It is unclear whether this has any implications at all, but this PR plugs the potential issue, if there ever is one, by shuffling the coins before they are grouped.

With watching only inputs, we do not know how large the signatures
for those inputs will be as their signers may not have implemented
71 byte signatures. Thus we estimate their fees using the 72 byte
dummy signature to ensure that we pay enough fees.
This only effects fundrawtransaction when includeWatching is true.

Pull request description:
This is pointed out in https://github.com/bitcoin/bitcoin/pull/12257#discussion_r204549758.
Basically, the ancestors gives an indication as to how many ancestors the resulting transaction will have, which is more precise when summing up the values, rather than taking the maximum, since all the coins in the group will become ancestors if selected.
