Pull request description:
After #18210 the `flake8` exit code in `test/lint/lint-python.sh` just not used that makes the linter broken.
This PR:
- combines exit codes of `flake8` and `mypy` into the `test/lint/lint-python.sh` exit code
- documents `mypy` as the test dependency

bd7e530f010d43816bb05d6f1590d1cd36cdaa2c This PR adds initial support for type hints checking in python scripts. (Kiminuo)
Pull request description:
This PR adds initial support for type hints checking in python scripts.
Support for type hints was introduced in Python 3.5. Type hints make it easier to read and review code in my opinion. Also an IDE may discover a potential bug sooner. Yet, as PEP 484 says: "It should also be emphasized that Python will remain a dynamically typed language, and the authors have no desire to ever make type hints mandatory, even by convention."
[Mypy](https://mypy.readthedocs.io/en/latest/index.html) is used in `lint-python.sh` to do the type checking. The package is standard so there is little chance that it will be abandoned. Mypy checks that type hints in source code are correct when they are not, it fails with an error.
**Notes:**
* [--ignore-missing-imports](https://mypy.readthedocs.io/en/latest/command_line.html#cmdoption-mypy-ignore-missing-imports) switch is passed on to `mypy` checker for now. The effect of this is that one does not need `# type: ignore` for `import zmq`. More information about import processing can be found [here](https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports). This can be changed in a follow-up PR, if it is deemed useful.
* We are stuck with Python 3.5 until 04/2021 (see https://packages.ubuntu.com/xenial/python3). When Python version is bumped to 3.6+, one can change:
```python
_opcode_instances = [] # type: List[CScriptOp]
```
to
```python
_opcode_instances:List[CScriptOp] = []
```
for type hints that are **not** function parameters and function return types.
**Useful resources:**
* https://docs.python.org/3.5/library/typing.html
* https://www.python.org/dev/peps/pep-0484/

ACK bd7e530f010d43816bb05d6f1590d1cd36cdaa2c - the type checking is not the most robust (there are things it fails to detect), but I think this is worth adopting (in a limited capacity while we maintain 3.5 compat).

b604c5c8b5892842f13dee89ae31812a28ab25d1 wallet: Minimal fix to restore conflicted transaction notifications (Russell Yanofsky)
Pull request description:
This fix is a based on the fix by Antoine Riard (ariard) in https://github.com/bitcoin/bitcoin/pull/18600.
Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd77eed497a8e251d31358e16e2f2eb1 and 7e89994133725125dddbfa8d45484e3b9ed51c6e from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325.
The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.

fa0f6c58c1c6d10f04c4e65a424cc51ebca50a8c Revert "Fix link error with --enable-debug" (MarcoFalke)
Pull request description:
This reverts a hacky workaround from commit b83cc0f, which only happens to work due to compiler optimizations. Then, it actually fixes the linker error.
The underlying problem is that the wallet includes symbols from the server (ui_interface), which usually results in linker failures. Though, in this specific case the linker failures have not been observed (unless `-O0`) because our compilers were smart enough to strip unused symbols.
Fix the underlying problem by creating a new header-only with the needed symbol and move ui_interface to node to clarify that this is part of libbitcoin_server.
