BACKPORT NOTICE
There's some difference with original PR but that's not important because we do not actually use travis.
The variable TRAVIS_BRANCH would be removed anyway in bitcoin#20697 - let's just skip it for simplicity

1b41ce8f5f3debae03ca60e4acada14680df9185 lint: Don't use TRAVIS_COMMIT_RANGE for commit-script-check (Fabian Jahr)
Pull request description:
This is causing problems again, very similar to #19654.
UPDATE: This now removes all remaining usages of TRAVIS_COMMIT_RANGE and instead uses TRAVIS_BRANCH for the range, including `lint-git-commit-check` where TRAVIS_COMMIT_RANGE had already been removed. For builds triggered by a pull request, TRAVIS_BRANCH is the name of the branch targeted by the pull request. In the linters there is still a fallback that assumes master as the target branch.

39d526bde48d98af4fa27906e85db0399b6aa8b1 test: Bump linter versions (Duncan Dean)
Pull request description:
As per #19346, `mypy==0.700` was incompatible with Python 3.8.
I've bumped the versions of all the linters to their latest stable versions.
Checked with both Python 3.7 and 3.8 and everything still seems to work fine.

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).

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.

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.
