Change shouldn't have any effect outside of the GUI. It just fixes a race

Pull request description:
Add logging of `CValidationInterface` callbacks using a new `VALIDATIONINTERFACE` log flag (see #12994). A separate flag is desirable as the logging can be noisy and thus may need to be disabled without affecting other logging.
This could help debug issues where there may be race conditions at play, such as #12978.

6d6a7a8403 gui: Fix duplicate wallet showing up (João Barbosa)
81ea66c30e Drop signal CClientUIInterface::LoadWallet (Russell Yanofsky)
Pull request description:
This PR includes 2 fixes:
- prevent GUI LoadWallet handlers from crashing on startup when multiple handlers are attached, because the first handler takes ownership of the wallet unique pointer. Now every handler will receive its own unique pointer;
- prevent showing a wallet twice in the GUI on startup due to a race with `loadwallet`.

3e730bf90a zmq: Fix due to invalid argument and multiple notifiers (João Barbosa)
Pull request description:
ZMQ initialization is interrupted if any notifier fails, and in that case all notifiers are destroyed. The notifier shutdown assumes that the initialization had occurred. This is not valid when there are multiple notifiers and any except the last fails to initialize.
Can be tested by running test/functional/interface_zmq.py from this branch with bitcoind from master.
Closes#17185.

60aba1f2f1 rpc: simplify getaddressinfo labels, deprecate previous behavior (Jon Atack)
7851f14ccf rpc: incorporate review feedback from PR 17283 (Jon Atack)
Pull request description:
This PR builds on #17283 (now merged) and is followed by #17585.
It modifies the value returned by rpc getaddressinfo `labels` to an array of label name strings and deprecates the previous behavior of returning an array of JSON hash structures containing label `name` and address `purpose` key/value pairs.
before
```
"labels": [
{
"name": "DOUBLE SPEND",
"purpose": "receive"
}
```
after
```
"labels": [
"DOUBLE SPEND"
]
```
The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=labelspurpose`.
For context, see:
- https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001
- http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-13.html#l-425 (lines 425-427)
- http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=labelspurpose` flag while verifying the rpc getaddressinfo help text and `labels` output.
Next steps: deprecate the rpc getaddressinfo `label` field (EDIT: done in #17585) and add support for multiple labels per address. This PR will unblock those.

Problem:
Without the regtest magic, genesis hash and path config, the `linearize-data.py` script cannot generate a bootstrap.dat file.
Example:
./linearize-data.py ./linearize.cfg
Read 102 hashes
Genesis block not found in hashlist
Solution:
Added netmagic, genesis and input example parameters to file.
Resolution
1. Starting bitcoind in regtest mode
2. bitcoin-cli generatetoaddress 101 $(bitcoin-cli getnewaddress)
3. ./linearize-hashes.py ./linearize.cfg > ./hashlist.txt
4. ./linearize-data.py ./linearize.cfg
```
$ ./linearize-data.py ./linearize.cfg
Read 102 hashes

Pull request description:
The miner needs read-only access to the mempool. Instead of using the mutable global `::mempool`, keep a immutable reference to a mempool that is passed to the miner. Apart from the obvious benefits of removing a global and making things immutable, this might also simplify testing with multiple mempools.

This new approach uses a static method which takes the object as
a argument. This has the advantage that its constness can be a
template parameter, allowing a single implementation that sees the
object as const for serialization and non-const for deserialization,
without casts.
More boilerplate is included in the new macro as well.

3bd8db80d8 [validation] fix comments in CheckInputScripts() (John Newbery)
6f6465cefc scripted-diff: [validation] Rename CheckInputs to CheckInputScripts (John Newbery)
Pull request description:
CheckInputs() used to check no double spends, scripts & sigs and amounts. Since
832e074, the double spend and amount checks
have been moved to CheckTxInputs(), and CheckInputs() now just validates
input scripts. Rename the function to CheckInputScripts().
Also fix incorrect comments.
