a31be09bfd77eed497a8e251d31358e16e2f2eb1 Encapsulate tx status in a Confirmation struct (Antoine Riard)
Pull request description:
While working on #15931, I've tried to rationalize tx state management to ease integration of block height tracking per-wallet tx. We currently rely on a combination of `hashBlock` and `nIndex` with magic value to determine tx confirmation, conflicted or abandoned state. It's hard to reason and error-prone. To solve that, we encapsulate these fields in a `TxConfirmation` struct and introduce a `TxState` member that we update accordingly at block connection/disconnection.
Following jnewbery [recommendation](https://github.com/bitcoin/bitcoin/pull/15931#discussion_r312576506), I've taken these changes in its own commit, and open a PR to get them first. It would ease review of aforementioned PR, but above all should ease fixing of long-term issues like :
* https://github.com/bitcoin/bitcoin/issues/7315 (but maybe we should abandon abandontransaction or relieve it to only free outpoints not track the transaction as abandoned in itself, need its own discussion)
* https://github.com/bitcoin/bitcoin/issues/8692 where we should cancel conflicted state of transactions chain smoothly
* `MarkConflicted` in `LoadToWallet` is likely useless if we track conflicts rights at block connection
Main changes of this PR to get right are tx update in `AddToWallet` and serialization/deserialization logic.

Pull request description:
This try block has accidentally been added by me in fa3e9f7627784ee00980590e5bf044a0e1249999.
It was unused all the time, but commit 6011c9d72d1df5c2cd09de6f85c21eb4f7eb1ba8 added a `return` in the finally block, muting all exceptions.
This can be tested by adding an `assert False` after any `with ...assert_debug_log...:` line.

Pull request description:
This is a second go at #15221, fixing new lints in:
W504 line break after binary operator
W605 invalid escape sequence
F841 local variable 'e' is assigned to but never used
This time around:
* One commit per rule, for easier review
* I went with the PEP-8 style of breaking before binary operators
* I looked into the raw regex newline issue, and found that raw strings with newlines embedded do work appropriately. E.g. run `re.match(r" \n ", " \n ")` to check this for yourself. `re.MULTILINE` exists to modify `^` and `$` in multiline scenarios, but all of these searches are per-line.

d48c1e837ae1bd08e0f18ad1b57ff72675c3d6ad Add window final block height to getchaintxstats (Jonathan "Duke" Leto)
Pull request description:
This patch is motivated by the desire to make the output of `getchaintxstats` more useful and optimized for applications to consume and render the data.
Firstly, this data is already available to the RPC, no additional work is done. Currently additional RPC calls will be needed to look up the height of the final block in the window or the block height that began the window.
By adding the block height of the final block in the window, the JSON is "self-contained" and applications can calculate the exact block height range of the window with no additional RPC requests.
For example, a web application which wants to render historical information for `getchaintxstats` RPC on various window sizes might call the RPC with various window lengths, once per day, and store the JSON results somewhere. Because the final block height of each dataset is included, it's no extra work to determine the exact block window range of each JSON response.

25dd86715039586d92176eee16e9c6644d2547f0 Avoid using mutable default parameter values (practicalswift)
Pull request description:
Avoid common Python default parameter gotcha when mutable `dict`/`list`:s are used as default parameter values.
Examples of this gotcha caught during review:
* https://github.com/bitcoin/bitcoin/pull/16673#discussion_r317415261
* https://github.com/bitcoin/bitcoin/pull/14565#discussion_r241942304
Perhaps surprisingly this is how mutable list and dictionary default parameter values behave in Python:
```
>>> def f(i, j=[], k={}):
... j.append(i)
... k[i] = True
... return j, k
...
>>> f(1)
([1], {1: True})
>>> f(1)
([1, 1], {1: True})
>>> f(2)
([1, 1, 2], {1: True, 2: True})
```
In contrast to:
```
>>> def f(i, j=None, k=None):
... if j is None:
... j = []
... if k is None:
... k = {}
... j.append(i)
... k[i] = True
... return j, k
...
>>> f(1)
([1], {1: True})
>>> f(1)
([1], {1: True})
>>> f(2)
([2], {2: True})
```
The latter is typically the intended behaviour.
This PR fixes two instances of this and adds a check guarding against this gotcha going forward :-)

6011c9d72d1df5c2cd09de6f85c21eb4f7eb1ba8 QA: fix rpc_setban.py race (Jonas Schnelli)
Pull request description:
The new `rpc_setban.py` test failes regularly on CIs due to a race between injecting the ban and testing the log "on the other side".
The problem is, that the test immediately after the `addnode` command on node0 checks for the `dropped (banned)` entry on node1 (without giving some time).
Adding a 2 seconds sleep seems to solve the race (I guess there is no better event-driven delay).
Example of a failed test: https://bitcoinbuilds.org/index.php?ansilog=bf743910-103f-4b54-9a97-960c471061bd.log#l2906

Pull request description:
Right now it's a bit annoying to deal with watchonly wallets, many rpc commands have an `include_watchonly` argument that needs to be explicitly set.
Wallets created with `createwallet` can have a `disable_private_keys` parameter, for those wallets we already know that they are watchonly, so there's no reason to have to explicitly ask for it for every command. Instead we check this wallet flag when the `include_watchonly` parameter isn't set.

This hardcodes CSV and segwit activation heights, similar to the BIP 90 buried deployments for BIPs 34, 65 and 66.
CSV and segwit have been active for over 18 months. Hardcoding the activation height is a code simplification, makes it easier to understand segwit activation status, and reduces technical debt.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal
---
This change encapsulates UTXO set data within CChainState instances, removing global data `pcoinsTip` and `pcoinsviewdb`. This is necessary if we want to maintain multiple chainstates with their own rendering of the UTXO set.
We introduce a class CoinsViews which consolidates the construction of a CCoins* hierarchy.
This commit could be broken into smaller pieces, but it would require more ephemeral diffs to, e.g., temporarily change CCoinsViewDB's constructor invocations.

Use colors and dots in `test_runner.py` output only if standard output is a terminal -- allows for using the test runner output as input to other programs.
I found the need for this when parsing `test_runner.py` output while investigating intermittent functional test failures.

```

This ...
* ensures that enough coins are available/spendable, even when more
variants are added
* ensures that all mempool txs are mined, even when more variants are
added
* makes the test more specific to test that the confirmation height
is properly reported and timestamps are correctly handled in the test
logic
* prepares the test for a future, where blocks are skipped for rescan if
they are deemed irrelevant by a filter (c.f. BIP157)
