3eac2d57b1ff563bc9cfe123f6ded2764cc50da0 docs: add "sections" info to example bitcoin.conf (Alistair Mann)
Pull request description:
Rebased / commit message fixed version of #15387.
This had ACKs, but just needed the commit message fixed up.
> Most bitcoin.conf options apply to all three networks,
however some apply only to mainnet unless specified in a section.
As stands, conf file has no indication that sections are now in use
or are in some circumstances mandatory (eg, changing rpcport for testnet.)
> Proposed change notifies the reader early which options are affected,
specifically adds those options affected but not already in the example,
adds brief explanation as to what's going on and provides a skeleton template for the sections themselves.

Pull request description:
Remove unreferenced local variables:
Increase signal to noise in appveyor build output by reducing the MSVC warning count from 12 to 4. 12 is the number of MSVC warnings under our current appveyor setup assuming the changes in #14086 are also implemented.
This makes it easier to spot errors or more important warnings in the verbose appveyor output. MSVC warnings are good, so having access to them in a noise free way (read: without trivial warnings) via appveyor without having to use Windows is really valuable.

fa9b60c842 Remove unused TransactionError constants (MarcoFalke)
Pull request description:
Fixup to #14978, which introduced a bunch of unused enum values, such as `UNKNOWN_ERROR`, `ERROR_COUNT` and `TRANSACTION_ERR_LAST`. None of those have a meaning in the context of an `enum class`, where the compiler can infer if all cases have been covered in a switch-case.
Also, move the global `::maxTxFee` back to the rpc caller, so it can be set on a per call basis (in the future).

Pull request description:
Replacing boost functionality with C++11 stuff.
Motivated by #18227, but should stand alone. Changing from `boost::condition_var` to `std::condition_var` means `threadGroup.interrupt_all` isn't enough to interrupt `serviceQueue` anymore, so that means calling `stop()` before `join_all()` is needed. And the existing reverselock.h code doesn't work with sync.h's DebugLock code (because the reversed lock won't be removed from `g_lockstack` which then leads to incorrect potential deadlock warnings), so I've replaced that with a dedicated class and macro that's aware of our debug lock behaviour.

Pull request description:
When building w/o wallet support, we add all the wallet options as hidden options to avoid throwing errors/warnings that they're unknown.
`-ignorepartialspends` is missing from this list. This PR adds it.
(This seems like a good candidate for a linter? Or maybe we can autogenerate it?)
Also reformats the dummywallet options list across multiple lines to make conflicts less often.

Merge #14324: qa: Run more tests with wallet disabled
faa4043c66 qa: Run more tests with wallet disabled (MarcoFalke)
Pull request description:
Instead of skipping the whole test, only skip the wallet specific section of a test if the wallet is not compiled in. This is mostly an indentation change, so can be reviewed with `--ignore-all-space`.

f9e37f33ce2d8b463a0bcbe7189c9bc5b36530b7 doc: IsFinalTx comment about nSequence & OP_CLTV (Yuval Kogman)
Pull request description:
It's somewhat surprising that a transaction's `nLockTime` field is ignored
when all `nSequence` fields are final, so this change aims to clarify this
behavior and cross reference relevant details of `OP_CHECKLOCKTIMEVERIFY`.

fa92e60f38cb109fe5a3c7acfe1017ffebc388cc refactor: Make httpserver work queue a unique_ptr (MarcoFalke)
Pull request description:
This simplifies the code a bit because `if (p) { delete p; p = nullptr; }` can be replaced by a call to the `reset()` member.

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:
![image](https://user-images.githubusercontent.com/7444140/121382910-57554880-c947-11eb-94f2-49da8679528c.png)
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:

3f05a9e681c4b72d99ddda8ccb6911d6ffad44ec zmq: use msg: prefix over errno= in zmqError (fanquake)
9a7cb57bbc61b2dfb772f8486db2a44c1673983a zmq: use std::string in zmqError() (fanquake)
Pull request description:
This is two minor changes. The first is to change `zmqError` to take a `const std::string&` instead of a `const char*`. The second is to change the second portion of `zmqError` to print `msg: message` rather than `errno=message`, given that `zmq_strerror` returns a message. To me, this seems more readable / useful than output like: `Error: Unable to initialize context errno=No such file or directory`.
