Have `combine_logs.py` default to the most recent test directory if no argument is provided. This allows you to avoid an annoying copy-paste when iterating on a failing test, since you can do something like

168b6c317ca054c1287c36be532964e861f44266 add dummy file param to fix jupyter (Josiah Baker)
Pull request description:
this fixes argparse to use `parse_known_args`. previously, if an unknown argument was passed, argparse would fail with an `unrecognized arguments: %s` error.
## why
the documentation mentions being able to run `TestShell` in a REPL interpreter or a jupyter notebook. when i tried to run inside a jupyter notebook, i got the following error:
this was due to the notebook passing the filename of the notebook as an argument. this is a known problem with notebooks and argparse, documented here: https://stackoverflow.com/questions/48796169/how-to-fix-ipykernel-launcher-py-error-unrecognized-arguments-in-jupyter
## testing
to test, make sure you have jupyter notebooks installed. you can do this by running:
```
pip install notebook
```
or following instructions from [here](https://jupyterlab.readthedocs.io/en/stable/getting_started/installation.html).
once installed, start a notebook (`jupyter notebook`), launch a python3 kernel and run the following snippet:
```python
import sys
# make sure this is the path for your system
sys.path.insert(0, "/path/to/bitcoin/test/functional")
from test_framework.test_shell import TestShell
test = TestShell().setup(num_nodes=2, setup_clean_chain=True)
```
you should see the following output, without errors:
if you are unfamiliar with notebooks, here is a short guide on using them: https://jupyter.readthedocs.io/en/latest/running.html

I have tried to be exhaustive as possible in maximum coverage for non-wallet mode without affecting any coverage for wallet mode.
However, I could not check the tests in wallet mode because of timeout issues. Hopefully, travis job checks those.
Tests `feature_block.py`, `feature_logging.py` and `feature_reindex.py` were skipping despite having no direct dependency on any wallet functions. So, I have also disabled the `skip_test_no_wallet()` for those files too.

- Print color output in functional tests for Windows 10
- Run util and functional tests on appveyor
- Do not run symlink tests on Windows
Note:
- The wallet_multiwallet.py fail is unrelated to the test framework, it's a bug related to c++ code or maybe dependencies. `bitcoind` would exit with 0xC0000005(Access violation) during shutdown occasionally. Disable this for now.
- Not using `--failfast` because this is still in experimental. We should track if there is any other error.
- Disable ZMQ tests because the python zmq library could cause access violation sometimes.
- Disable `feature_notifications` because Bitcoin Core handles the command in different thread, whicha can cause a race condition.

Pull request description:
From #19580
This PR changes comments to clarify the intended usage of `message_count` and `last_message`. Additionally it changes the only usage of `message_count` to use `last_message` instead, bringing the code into alignment with the intended usage.
Note: Now `message_count` is completely unused. However, it is ready to be used (i.e. the supporting code works) and likely will be used in some test in the future.

8f5d9431a Add regtests for HTTP status codes. (Daniel Kraft)
Pull request description:
This adds explicit tests for the returned HTTP status codes to `interface_rpc.py` (for error cases) and the HTTP JSON-RPC client in general for success.
#15381 brought up discussion about the HTTP status codes in general, and the general opinion was that the current choice may not be ideal but should not be changed to preserve compatibility with existing JSON-RPC clients. Thus it makes sense to actually test the current status to ensure this desired compatibility is not broken accidentally.

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

fa3e5786d0 scripted-diff: Remove unused 'split' parameter to setup_network (MarcoFalke)
Pull request description:
This is a bugfix, since wallet_dump currently uses the wrong name:
18857b4c40/test/functional/wallet_dump.py (L89-L92)
Rename all to the same name with a scripted diff (and some unrelated cleanups).

c82190cdb6 tests: Add Python dead code linter (vulture) (practicalswift)
590a57fdec tests: Remove unused testing code (practicalswift)
Pull request description:
Add Python dead code linter (`vulture`) to Travis.
Rationale for allowing dead code only after explicit opt-in (via `--ignore-names`):
* Less is more :-)
* Unused code is by definition "untested"
* Unused code can be an indication of bugs/logical errors. By making the contributor aware of newly introduced unused code it gives him/her an opportunity to investigate if the unused code they introduce is malignant or benign :-)
* Unused code is hard to spot for humans and is thus often missed during manual review
* [YAGNI](https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it)
Based on #14312 to make linter job pass.

The node might crash or disconnect when our mininode waits for data. Due to the crash, the data is guaranteed to never arrive and we can fail early with an assert
