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.

57889e688dd0987a1e087cd48d216a413127601e bitcoin-tx: Stricter check for valid integers (Daniel Kraft)
Pull request description:
Just calling `atoi` to convert strings to integers does not check for valid integers very thoroughly; in particular, it just ignores everything starting from the first non-numeral character. Even a string like "foo" is fine and silently returns 0.
This meant that `bitcoin-tx` would not fail if such a string was passed in various places where an integer is expected (like the `locktime` or an input/output index); this means that it would, for instance, silently accept a typo and interpret it in an unexpected way.
In this change, we use `ParseInt64` for parsing strings to integers, which actually verifies that the full string is valid as number. New tests in the `bitcoin-util-test` cover the new error paths.
This fixes#13599.

6be7d14d243eeeaaf6b4b98c3359c3e1695f2046 Properly generate salt in rpcauth.py, update tests (Carl Dong)
Pull request description:
Previously, when iterating over bytes of the generated salt to construct
a hex string, only one character would be outputted when the byte is
less than 0x10. Meaning that for a 16 byte salt, the hex string might be
less than 32 characters and collisions would occur.

dac3782 doc: Correct AmountFromValue/ValueFromAmount names (Wladimir J. van der Laan)
Pull request description:
With this, the amounts returned in `decoderawtransaction` will be padded to 8 digits like anywhere else in the API.
This is accomplished by using `ValueFromAmount` in `TxToUniv`, instead of `FormatMoney` which it currently (mistakingly) uses. The `FormatMoney` function is only for debugging/logging use!
To avoid dependency issues, `ValueFromAmount` is moved to `core_write.cpp`, where it also fits better. I don't move `AmountFromValue` to `core_read.cpp` at the same time, as this would have more impact due to the RPCError dependency there.
(n.b.: large number of changed files is solely due to the util_tests JSONs needing update)
