0) Adjust BIP30 enforcement values
1) Reduce amount that peers can adjust our time to eliminate an attack vector. Thanks to
coblee for this fix.
2) Zeitgeist2 patch - thanks to Lolcust and ArtForz. This fixes an issue where a
51% attack can change difficulty at will. Go back the full period unless it's the
first retarget after genesis.
3) Avoid overflow in CalculateNextWorkRequired(). Thanks to pooler for the overflow fix.
4) Zeitgeist2 bool fshift bnNew.bits(). Thanks to romanornr for this path.
5) SegWit ContextualCheckBlockHeader adjustment and extra coverage.
6) Reject peer proto version below 70002. Thanks to wtogami for this patch.
7) Send final alert message to nodes warning about removal of the alert system. Thanks to coblee for this patch.
8) Adjust default settings for Litecoin.
9) Adjust STALE_CHECK_INTERVAL value

Current backports for *0.21.1*.
One conflict was in the test case.
ACKs for top commit:
ajtowns:
ACK 5a2d98c640 -- checked 'rebased-from' patches are in master, and rebased patches are clean rebases (except for the first one which changes `""s` to `std::string("")` to avoid c++17 dependency). commits seem fine, but haven't reviewed in detail.
fanquake:
ACK 5a2d98c640 - branched off `0.21` and redid the backports. Minor conflict in c33fbab25c. The diff between my branch and #20901 was just in release notes, `_CLIENT_VERSION_RC` (#20901 branched before 95ea54ba08) and #21490 which has already been merged into `0.21`.

38ada892ed addrman: ensure old versions don't parse peers.dat (Vasil Dimov)
Pull request description:
Even though the format of `peers.dat` was changed in a backwards
incompatible way, it is not guaranteed that old versions will fail to
parse it. There is a chance that old versions parse its contents as
garbage and use it.
Old versions expect the "key size" field to be 32 and fail the parsing
if it is not. Thus, we put something other than 32 in it. This will make
versions between 0.11.0 and 0.20.1 deterministically fail on the new
format. Versions prior to https://github.com/bitcoin/bitcoin/pull/5941
will still parse it as garbage.
Also, introduce a way to increment the `peers.dat` format in a way that
does not necessary make older versions refuse to read it.

7b54d768e1 Make sqlite support optional (compile-time) (Luke Dashjr)
Pull request description:
As a new requirement, sqlite support should be optional. This PR aims to be only minimum/blocker changes for 0.21.
Potential follow-up PRs after this:
* Make BDB support optional
* Nicer error messages when user tries to load an unsupported wallet
* Don't compile descriptor wallet code if sqlite disabled

This PR is a #19077 follow up, and it addresses the [comment](https://github.com/bitcoin/bitcoin/pull/19077#discussion_r504805234):
> If need to update, there are two corrections that could be made:
>
> * Line 69 "Wallets are Berkeley DB (BDB) databases" is no longer true
>
> * Line 76 "Wallet lock file" should say "BDB wallet lock file"
