wallet: bugfix, invalid crypted key "checksum_valid" set
At wallet load time, we set the crypted key "checksum_valid" variable always to false.
Which, on every wallet decryption call, forces the process to re-write the entire ckeys to db when
it's not needed.

Pull request description:
This adds better test coverage and will make it easier in #20744 to remove our dependency on the two-argument boost::filesystem::absolute() function which does not have a direct equivalent in C++17.
This PR doesn't change behavior aside from adding an assert and fixing a test bug.

fd6580e405699ccb051fd2a34525e48d3253673d [refactor] txmempool: split epoch logic into class (Anthony Towns)
Pull request description:
Splits the epoch logic introduced in #17925 into a separate class.
Uses clang's thread safety annotations and encapsulates the data more strongly to reduce chances of bugs from API misuse.

jonatack:
ACK fd6580e405699ccb051fd2a34525e48d3253673d using clang thread safety annotations looks like a very good idea, and the encapsulation this change adds should improve robustness (and possible unit test-ability) of the code. Verified that changing some of the locking duly provoked build-time warnings with Clang 9 on Debian and that small changes in the new `Epoch` class were covered by failing functional test assertions in `mempool_updatefromblock.py`, `mempool_resurrect.py`, and `mempool_reorg.py`

ff44cae279bef7997f76db18deb1e41b39f05cb6 test: Change feature_config_args.py not to rely on strange regtest=0 behavior (Russell Yanofsky)
Pull request description:
Update test to simply generate a normal mainnet configuration file instead of using a crazy setup where a regtest=1 config file using an includeconf in the [regtest] section includes another config file that specifies regtest=0, retroactively switching the network to mainnet.
This setup was fragile and only worked because the triggered InitError happened early enough that none of the ignored [regtest] options mattered (only affecting log output).
This change was originally made as part of #17493

fa4e088cbac035b8029a10b492849540150d0622 wallet: Mark replaced tx to not be in the mempool anymore (MarcoFalke)
Pull request description:
The wallet does not mark the replaced tx as out-of-mempool. This causes failures in user scripts, because later RPCs may depend on this state change from `bumpfee`.
For example, the following might fail on current master:
```
txid = sendtoaddress(...)
bumpfee(txid)
abandontransaction(txid) # fails because txid is still marked as "in mempool"
```

Consensus-wise we already treat it as an unsigned integer (the

the underlying data type means touching consensus code for a
simple cleanup change, which isn't really worth it.

Pull request description:
This PR adds support for ZeroMQ to listen on multiple interfaces, just like the RPC server.
Currently, if you specify more than one e.g. `zmqpubhashblock` paramter, only the first one will be used. Therefore a user may be forced to listen on all interfaces (e.g. `zmqpubhashblock=0.0.0.0:28332`), which can result in an increased attack surface.
With this PR a user can specify multiple interfaces to listen on, e.g.
`-zmqpubhashblock=tcp://127.0.0.1:28332 -zmqpubhashblock=tcp://192.168.1.123:28332`.

2b9cba206594bfbcefcef0c88a0bf793819643bd Remove CWalletTx merging logic from AddToWallet (Russell Yanofsky)
Pull request description:
This is a pure refactoring, no behavior is changing.
Instead of AddToWallet taking a temporary CWalletTx object and then potentially merging it with a pre-existing CWalletTx, have it take a callback so callers can update the pre-existing CWalletTx directly.
This makes AddToWallet simpler because now it is only has to be concerned with saving CWalletTx objects and not merging them.
This makes AddToWallet calls clearer because they can now make direct updates to CWalletTx entries without having to make temporary objects and then worry about how they will be merged.
Motivation for this change came from the bumpfee PR #8456 where we wanted to be able to call AddToWallet to make a simple update to an existing transaction, but were reluctant to, because the existing CWalletTx merging logic did not apply and seemed dangerous try to update as part of that PR. After this refactoring, the bumpfee PR could call AddToWallet safely instead of implementing a duplicate AddToWallet function.
This also allows getting rid of the CWalletTx copy constructor to prevent unintentional copying.

5efc25f9638866941028454cfa9bae27f1519cb4 [wallet] translate "Keypool ran out" message (Sjors Provoost)
Pull request description:
Extracted from #16944
First this PR simplifies the check when generating a change address, by dropping `CanGetAddresses` and just letting `reservedest.GetReservedDestination` do this check.
Second, when the keypool is empty, instead of immediately giving up, we create a dummy change address and pass that to coin selection. If we didn't need the change address (e.g. when spending the entire balance), then it's all good. If we did need a change address, we throw the original error.

fa60afc4fb957875bab1c8982d9d9e4999a3814c wallet: Add BlockUntilSyncedToCurrentChain to dumpwallet (MarcoFalke)
Pull request description:
dumpwallet includes the block hash in the output, so this method depends on the chainstate. According to the developer notes e84a5f0004/doc/developer-notes.md (L1095) it must include a `BlockUntilSyncedToCurrentChain`.
This is a minor fix and does not need backport, I think.
It fixes test failures such as https://travis-ci.org/github/bitcoin/bitcoin/jobs/675487097#L2657 , which can only happen in master because the test was not backported.

Some changes are missing or incorrectly backported during CWallet refactoring in #17260, #17261 such as:
- Missing changes for CWallet::GetOldestKeyPoolTime
- useless check of spk_man existance in getnewaddress
- GetHDChain is used assuming it exists only legacy keymanager
- using internal spk_man API instead wallet's in getwalletinfo
34c80d9eee7d21755f2bb80f7c97fd30d2c7b656 test: Add option to git-subtree-check to do full check, add help (Wladimir J. van der Laan)
Pull request description:
This adds a brief help text to `git-subtree-check.sh` and adds an option to do a full remote check instead of having two different code paths with a successful exit status. Also make it explicit that the CI is not doing this.

Pull request description:
Running `git-subtree-check.sh` requires adding the subtree repository as a remote. I learned that several years ago and then forgot again.
This PR also improves the error message if the subtree commit can't be found.

487aff421 Check subtree consistency in Travis (Pieter Wuille)
e1d0cc23a Improve git-subtree-check.sh (Pieter Wuille)
Pull request description:
Apparently many of our subtrees get modified by PRs in this repository, without getting noticed.
To improve upon this:
* Make git-subtree-check.sh capable of doing a weaker consistency check (that doesn't need access to external repositories), but which should be sufficient to detect unintended changes. It can be fooled by a fake subtree merge commit, but that would hopefully be obvious to reviewers.
* Make Travis invoke this subtree check for each of our subtrees.
Note that Travis is currently expected to fail on this PR, as 2 out of 4 subtrees (`src/secp156k1` and `src/univalue` have been modified directly in master).
