## Issue being fixed or feature implemented
same as #5392, alternative solution
~based on #5402 atm, will rebase later~
## What was done?
pls see individual commits
## How Has This Been Tested?
reorg mainnet around forkpoint with a patched client (to allow low
difficulty), run tests
## Breaking Changes
Another evodb migration is required. Going back to an older version or
migrating after the fork requires reindexing.

## Issue being fixed or feature implemented
Many objects created and functions called by passing `const
std::unique_ptr<Obj>& obj` instead directly passing `Obj& obj`
In some cases it is indeed needed, but in most cases it is just extra
complexity that is better to avoid.
Motivation:
- providing reference to object instead `unique_ptr` is giving warranty
that there's no `nullptr` and no need to keep it in mind
- value inside unique_ptr by reference can be changed externally and
instead `nullptr` it can turn to real object later (or in opposite)
- code is shorter but cleaner
Based on that this refactoring is useful as it reduces mental load when
reading or writing code.
`std::unique` should be used ONLY for owning object, but not for passing
it everywhere.
## What was done?
Replaced most of usages `std::unique_ptr<Obj>& obj` to `Obj& obj`.
Btw, in several cases implementation assumes that object can be nullptr
and replacement to reference is not possible.
Even using raw pointer is not possible, because the empty
std::unique_ptr can be initialized later somewhere in code.
For example, in `src/init.cpp` there's called `PeerManager::make` and
pass unique_ptr to the `node.llmq_ctx` that would be initialized way
later.
That is out of scope this PR.
List of cases, where reference to `std::unique_ptr` stayed as they are:
- `std::unique_ptr<LLMQContext>& llmq_ctx` in `PeerManagerImpl`,
`PeerManager` and `CDSNotificationInterface`
- `std::unique_ptr<CDeterministicMNManager>& dmnman` in
`CDSNotificationInterface`
Also `CChainState` have 3 references to `unique_ptr` that can't be
replaced too:
- `std::unique_ptr<llmq::CChainLocksHandler>& m_clhandler;`
- `std::unique_ptr<llmq::CInstantSendManager>& m_isman;`
- `std::unique_ptr<llmq::CQuorumBlockProcessor>&
m_quorum_block_processor;`
## How Has This Been Tested?
Run unit/functional tests.
## Breaking Changes
No breaking changes, all of these changes - are internal APIs for Dash
Core developers only.

1ef28b4f7cfba410fef524def1dac24bbc4086ca Make AnalyzePSBT next role calculation simple, correct (Gregory Sanders)
Pull request description:
Sniped test and alternative to https://github.com/bitcoin/bitcoin/pull/18220
Sjors documenting the issue:
```
A PSBT signed by ColdCard was analyzed as follows (see #17509 (comment))
{
"inputs": [
{
"has_utxo": true,
"is_final": false,
"next": "finalizer"
}
],
"estimated_vsize": 141,
"estimated_feerate": 1e-05,
"fee": 1.41e-06,
"next": "signer"
}
I changed AnalyzePSBT so that it returns "next": "finalizer" instead.
```
It makes it much clearer that the role has been decided before hitting the `calc_fee` block, and groups all state-deciding in one spot instead of 2.
Note that this assumes that PSBT roles are a complete ordering, which for now and in the future seems to be a correct assumption.

b86cd155f6f661052042048aa7cfc2a397afe4f7 scripted-diff: Wallet: Rename mapAddressBook to m_address_book (Luke Dashjr)
Pull request description:
In many places, our code assumes that presence in the address book indicates a non-change key, and absence of an entry in mapAddressBook indicates change.
This no longer holds true after #13756 (first released in 0.19) since it added a "used" DestData populated even for change addresses. Only avoid-reuse wallets should be affected by this issue.
Thankfully, populating DestData does not write a label to the database, so we can retroactively fix this (so long as the user didn't see the change address and manually assign it a real label).
Fixing it is accomplished by:
* Adding a new bool to CAddressBookData to track if the label has ever been assigned, either by loading one from the database, or by assigning one at runtime.
* `CAddressBookData::IsChange` and `CWallet::FindAddressBookEntry` are new methods to assist in excluding change from code that doesn't expect to see them.
* For safety in merging, `CAddressBookData::name` has been made read-only (the actual data is stored in `m_label`, a new private member, and can be changed only with `setLabel` which updates the `m_change` flag), and `mapAddressBook` has been renamed to `m_address_book` (to force old code to be rebased to compile).
A final commit also does some minor optimisation, avoiding redundant lookups in `m_address_book` when we already have a pointer to the `CAddressBookData`.

Pull request description:
This PR builds on #17578 (now merged) and deprecates the rpc getaddressinfo `label` field. The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=label`.
See http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622 and https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001 for more context.
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=label` flag while verifying the rpc getaddressinfo output and help text.
Next step: add support for multiple labels.

0ed2d8e07d3806d78d03a77d2153f22f9d733a07 test: add BIP37 remote crash bug [CVE-2013-5700] test to p2p_filter.py (Sebastian Falbesoner)
Pull request description:
Integrates the missing message type `filteradd` to the test framework and checks that the BIP37 implementation is not vulnerable to the "remote crash bug" [CVE-2013-5700](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-5700) anymore. Prior to v.0.8.4, it was possible to trigger a division-by-zero error on the following line in the function `CBloomFilter::Hash()`:
f0d6487e29/src/bloom.cpp (L45)
By setting a zero-length filter via `filterload`, `vData.size()` is 0, so the modulo operation above, called on any .insert() or .contains() operation then crashed the node. The test uses the approach of just sending an arbitrary `filteradd` message after, which calls `CBloomFilter::insert()` (and in turn `CBloomFilter::Hash()`) on the node. The vulnerability was fixed by commit 37c6389c5a (an intentional covert fix, [according to gmaxwell](https://github.com/bitcoin/bitcoin/issues/18483#issuecomment-608224095)), which introduced flags `isEmpty`/`isFull` that wouldn't call the `Hash()` member function if `isFull` is true (set to true by default constructor).
To validate that the test fails if the implementation is vulnerable, one can simply set the flags to false in the member function `UpdateEmptyFull()` (that is called after a filter received via `filterload` is constructed), which activates the vulnerable code path calling `Hash` in any case on adding or testing for data in the filter:
```diff
diff --git a/src/bloom.cpp b/src/bloom.cpp
index bd6069b..ef294a3 100644
--- a/src/bloom.cpp
+++ b/src/bloom.cpp

Pull request description:
Only libFuzzer is supported right now, so clang is required. Thus, this needs a workaround such as https://github.com/bitcoin/bitcoin/issues/12602#issuecomment-562788247
Can be tested with:
```
mkdir build && cd build
../configure --enable-fuzz --with-sanitizers=fuzzer --enable-lcov --enable-lcov-branch-coverage CC=clang CXX=clang++
make $MAKEJOBS
make cov_fuzz

Approaches another missing unit test of issue #17394: Checks that the function `IsStandardTx()` returns rejection reason "scriptsig-not-pushonly" if any one of the input's scriptSig consists of any other ops than just PUSHs.

89fb241c54fc85befacfa3703d8e21bf3b8a76eb Benchmark script verification with 100 nested IFs (Pieter Wuille)
Pull request description:
While investigating what mechanisms are possible to maximize the per-opcode verification cost of scripts, I noticed that the logic for determining whether a particular opcode is to be executed is O(n) in the nesting depth. This issue was also pointed out by Sergio Demian Lerner in https://bitslog.wordpress.com/2017/04/17/new-quadratic-delays-in-bitcoin-scripts/, and this PR implements a variant of the O(1) algorithm suggested there.
This is not a problem currently, because even with a nesting depth of 100 (the maximum possible right now due to the 201 ops limit), the slowdown caused by this on my machine is around 70 ns per opcode (or 0.25 s per block) at worst, far lower than what is possible with other opcodes.
This PR mostly serves as a proof of concept that it's possible to avoid it, which may be relevant in discussions around increasing the opcode limits in future script versions. Without it, the execution time of scripts can grow quadratically with the nesting depth, which very quickly becomes unreasonable.
This improves upon #14245 by completely removing the `vfExec` vector.
