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

38ada892ed0ed9aaa46b1791db12a371a3c0c419 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.

01476a88a6095fd3af71cb9bf1eadef920a1197b wallet: Make -wallet setting not create wallets (Russell Yanofsky)
Pull request description:
This changes `-wallet` setting to only load existing wallets, not create new ones.
- Fixes settings.json corner cases reported by sjors & promag: https://github.com/bitcoin-core/gui/issues/95, https://github.com/bitcoin/bitcoin/pull/19754#issuecomment-685858578, https://github.com/bitcoin/bitcoin/pull/19754#issuecomment-685858578
- Prevents accidental creation of wallets reported most recently by jb55 http://www.erisian.com.au/bitcoin-core-dev/log-2020-09-14.html#l-355
- Simplifies behavior after #15454. #15454 took the big step of disabling creation of the default wallet. This PR extends it to avoid creating other wallets as well. With this change, new wallets just aren't created on startup, instead of sometimes being created, sometimes not. #15454 release notes are updated here and are simpler.
This change should be targeted for 0.21.0. It's a bug fix and simplifies behavior of the #15937 / #19754 / #15454 features added in 0.21.0.

This PR is implementing the simplest, most basic alternative listed in https://github.com/bitcoin-core/gui/issues/95#issuecomment-694236940. Other improvements mentioned there can build on top of this.

Pull request description:
This is an implementation of #17326:
- all (currently 2) outbound block-relay-only connections (#15759) are dumped to `anchors.dat` file
- on restart a node tries to connect to the addresses from `anchors.dat`
This PR prevents a type of eclipse attack when an attacker exploits a victim node restart to force it to connect to new, probably adversarial, peers.

Pull request description:
This PR adds a new class `SQLiteDatabase` which is a subclass of `WalletDatabase`. This provides access to a SQLite database that is used to store the wallet records. To keep compatibility with BDB and to complexity of the change down, we don't make use of many SQLite's features. We use it strictly as a key-value store. We create a table `main` which has two columns, `key` and `value` both with the type `blob`.
For new descriptor wallets, we will create a `SQLiteDatabase` instead of a `BerkeleyDatabase`. There is no requirement that all SQLite wallets are descriptor wallets, nor is there a requirement that all descriptor wallets be SQLite wallets. This allows for existing descriptor wallets to work as well as keeping open the option to migrate existing wallets to SQLite.
We keep the name `wallet.dat` for SQLite wallets. We are able to determine which database type to use by searching for specific magic bytes in the `wallet.dat` file. SQLite begins it's files with a null terminated string `SQLite format 3`. BDB has `0x00053162` at byte 12 (note that the byte order of this integer depends on the system endianness). So when we see that there is a `wallet.dat` file that we want to open, we check for the magic bytes to determine which database system to use.
I decided to keep the `wallet.dat` naming to keep things like backup script to continue to function as they won't need to be modified to look for a different file name. It also simplifies a couple of things in the implementation and the tests as `wallet.dat` is something that is specifically being looked for. If we don't want this behavior, then I do have another branch which creates `wallet.sqlite` files instead, but I find that this direction is easier.

Code review ACK c4a29d0a90b821c443c10891d9326c534d15cf97. I am honestly confused about reasons for locking into `wallet.dat` again when it's so easy now to use a clean format. I assume I'm just very dense, or there's some unstated reason, because the only thing that's been brought up are unrealistic compatibility scenarios (all require actively creating a wallet with non-default descriptor+sqlite option, then trying to using the descriptor+sqlite wallets with old software or scripts and ignoring the results) that we didn't pay attention to with previous PRs like #11687, which did not require any active interfaction.

Pull request description:
This replaces the transaction request logic with an encapsulated class that maintains all the state surrounding it. By keeping it stand alone, it can be easily tested (using included unit tests and fuzz tests).
The major changes are:
* Announcements from outbound (and whitelisted) peers are now always preferred over those from inbound peers. This used to be the case for the first request (by delaying the first request from inbound peers), and a bias afters. The 2s delay for requests from inbound peers still exists, but after that, if viable outbound peers remain for any given transaction, they will always be tried first.
* No more hard cap of 100 in flight transactions per peer, as there is less need for it (memory usage is linear in the number of announcements, but independent from the number in flight, and CPU usage isn't affected by it). Furthermore, if only one peer announces a transaction, and it has over 100 in flight already, we still want to request it from them. The cap is replaced with a rule that announcements from such overloaded peers get an additional 2s delay (possibly combined with the existing 2s delays for inbound connections, and for txid peers when wtxid peers are available).
* The limit of 100000 tracked announcements is reduced to 5000; this was excessive. This can be bypassed using the PF_RELAY permission (to accommodate locally dumping a batch of many transactions).
This replaces #19184, rebased on #18044 and with many small changes.

Code Review ACK fd9a006. I've reviewed the new TxRequestTracker, its integration in net_processing, unit/functional/fuzzing test coverage. I looked more for soundness of new specification rather than functional consistency with old transaction request logic.

Code Review ACK fd9a006. I've reviewed everything, mostly to see how this stuff works at the lower level (less documentation-wise, more implementation-wise), and to try breaking it with unexpected sequences of events.

WIP light ACK fd9a0060f028a4c01bd88f58777dea34bdcbafd1 have read the code, verified that each commit is hygienic, e.g. debug build clean and tests green, and have been running a node on and off with this branch and grepping the net debug log. Am still unpacking the discussion hidden by GitHub by fetching it via the API and connecting the dots, storing notes and suggestions in a local branch; at this point none are blockers.

Light code review ACK fd9a0060f028a4c01bd88f58777dea34bdcbafd1, looking at txrequest implementation, unit test implementation, and net_processing integration, just trying to understand how it works and looking for anything potentially confusing in the implementation. Didn't look at functional tests or catch up on review discussion. Just a sanity check review focused on:

Pull request description:
Pretty trivial... addresses some tiny comments from #19339. Also fixes a docs typo from #19940 and adds a release note about the error message change for testmempoolaccept.

Maintaining up to 100000 INVs per peer is excessive, as that is far more
than fits in a typical mempool.
Also disable the "overload" penalty for PF_RELAY peers.
