2c448d6bc7 parameterize hard coded numbers referring to miner conf window (Jordan Baczuk)
Pull request description:
Replace hard coded values (eg. 2016) with `mainnetParams.nMinerConfirmationWindow` where appropriate. This parameterizes hard coded values in the unit test that refer to the `Miner Confirmation Window`, which currently is `2016`. This includes values not exactly 2016 but which were derived from it. Also changed `int` to `uint32_t` where appropriate to avoid compiler warnings. This makes one source of truth, and also helps people who might be adjusting this value in testing so the unit tests don't break.

e0eae1b4a4 Make --setup command independent (Hennadii Stepanov)
Pull request description:
This PR allows a user to run:
```sh
./gitian-build.py --setup
```
without unused `signer` and `version` options.
In master the `signer` and `version` options are mandatory. This implies the following code is dead:
387eb5b343/contrib/gitian-build.py (L192-L200)
This PR fixes those lines of code.
Also this PR has a nice side effect: there is no more warnings about macOS build during processing `--setup` command. Ref: https://github.com/bitcoin/bitcoin/pull/13998#issuecomment-493691117
Note: https://github.com/bitcoin-core/docs/blob/master/gitian-building.md will be updated when this PR is merged.

fa2b52af32 Disallow extended encoding for non-witness transactions (take 3) (MarcoFalke)
Pull request description:
(previous title "p2p: Disallow extended encoding for non-witness transactions (take 3)")
Remote peers can send us illegally encoded txs and thus have us write to stderr. Fix that by not writing to stderr.
This is a follow up to the previous (incomplete) attempts at this:
* Disallow extended encoding for non-witness transactions #14039
* Add test for superfluous witness record in deserialization #15893

utACK fa2b52af32. Would change title to something like "Avoid logging transaction decode errors to stderr" instead of "Disallow extended encoding for non-witness transactions." The current title is confusing because this PR isn't really allowing or disallowing anything, just logging the condition differently. "Disallow" also seems to contradict the "Allow exceptions from..." comments in the actual code.

This patch improves the built-in RNG using hash strengthening.
At startup, and once every minute, 32 bytes of entropy are produced from the RNG, repeatedly hashed using SHA512 for 10ms, and then fed back into the RNG, together with high-precision timestamps obtained every 1000 iterations.

01971da9bd docs: Add productivity notes for "dummy rebases" (Carl Dong)
Pull request description:
When rebasing, we often want to do a "dummy rebase" whereby we are not rebasing over an updated master. This is because rebases can be confusing enough already, and we don't want to resolve upstream conflicts together with our local rebase conflicts due to fixup commits, commit rearrangements, and such. This productivity section details how to do such "dummy rebase"s.

463921bb64 CKey: add method to negate the key (Jonas Schnelli)
Pull request description:
This adds a limited implementation of `HKDF` (defined by rfc5869) that supports only HMAC-SHA256 and length output of 32 bytes (will be required for v2 transport protocol).
This PR also includes a method to negate a private key which is useful to enforce public keys starting with 0x02 (or 0x03) (a requirement for the v2 transport protocol). The new `CKey::Negate()` method is pretty much a wrapper around `secp256k1_ec_privkey_negate()`.
Including tests.
This is a subset of #14032 and a pre-requirement for the v2 transport protocol.

This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is
* that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
* that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.
