faaee1e39a test: Use connect_nodes when connecting nodes in the test_framework (MarcoFalke)
1111bb91f5 test: Reformat python imports to aid scripted diff (MarcoFalke)
Pull request description:
By default all test nodes are connected in a chain. However, instead of just a single connection between each pair of nodes, we end up with up to four connections for a "middle" node (two outbound, two inbound, from each side).
This is generally redundant (tx and block relay should succeed with just a single connection) and confusing. For example, test timeouts after a call to `sync_` may be racy and hard to reproduce. On top of that, the test `debug.log`s are hard to read because txs and block invs may be relayed on the same connection multiple times.
Fix this by inlining `connect_nodes_bi` in the two tests that need it, and then replace it with a single `connect_nodes` in all other tests.
Historic background:
`connect_nodes_bi` has been introduced as a (temporary?) workaround for bug #5113 and #5138, which has long been fixed in #5157 and #5662.

2dfd6834ef test: Add test for default maxfeerate in sendrawtransaction (Joonmo Yang)
261843e4be wallet/rpc: Use the default maxfeerate value as BTC/kB (Joonmo Yang)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/16382
This patch tries to treat `maxfeerate` in sendrawtransaction/testmempoolaccept RPC as a rate(BTC/kB) instead of an absolute value(BTC).
The included test case checks if the new behavior works correctly, by using the transaction with an absolute fee of ~0.02BTC, where the fee rate is ~0.2BTC/kB.
This test should be failing if the default `maxfeerate` is 0.1BTC, but pass if the default value is 0.1BTC/kB

This functional test includes two scenarios that test for regressions of vulnerabilities, but they are only briefly described. There are freely available documents explaining in detail the issues, but without explicit mentions, the developer trying to maintain the code needs an additional step of digging in commit history and PR conversations to figure it out.
Added comments to explicitly mention CVE-2018-17144 and CVE-2012-2459, for more complete documentation.

Pull request description:
Although there is an existing `test/lint/lint-whitespace.sh` linter, it only prevents new errors from being introduced. This commit removes all existing whitespace errors from Core markdown files (skips `src/crypto/ctaes/`, `leveldb/`, and `doc/release-notes/`), `bitcoin.conf`, and `Info.plist.in`.
Further formatting could be done on the markdown documents, but seeing as there several coexisting styles that break a few `markdownlint` rules, a first step would be to define and add a linter to Travis. For now, the small fix is made.

1b41c2c8a1 test: improve gettransaction test coverage (Jon Atack)
0f34f54888 rpc: fix regression in gettransaction (Jon Atack)
Pull request description:
Closes#16872.
PR #16866 renamed the `decode` argument in gettransaction to `verbose` to make it more consistent with other RPC calls like getrawtransaction. However, it inadvertently overloaded the "details" field when `verbose` is passed. The result is that the original "details" field is no longer returned correctly, which seems to be a breaking API change.
This PR:
- takes the simplest path to restoring the "details" field by renaming the decoded one back to "decoded" while leaving the `verbose` argument for API consistency, which was the main intent of #16866,
- addresses [this comment](https://github.com/bitcoin/bitcoin/pull/16185#discussion_r320740413) by mentioning in the RPC help that the new decoded field is equivalent to decoderawtransaction, and
- updates the help, functional test, and release note.
Reviewers, to test this manually, build and run `bitcoin-cli help gettransaction` and `bitcoin-cli gettransaction <wallet txid> false true`, and verify that the command returns both `details` and `decoded` fields.

Starting bitcoind with `-onlynet=onion` immediately after adding bitcoind user to debian-tor group will yield the following notice on debug.log:
"tor: Authentication cookie /run/tor/control.authcookie could not be opened (check permissions)"
Elaborate on the need to re-login to ensure debian-tor group has been applied to bitcoind user after:
sudo usermod -a -G debian-tor username
Verification can be done via `groups` command in shell.

Pull request description:
This adds a checkbox to the intro screen to enable pruning from the get go.
If the user has plenty of space, it's unchecked by default:

If the user has insufficient space it's checked by default:

When the user has barely enough space and is likely to need pruning in the near future, this is shown in yellow and we also check the prune box:

The cut-off for this 10 GB above `m_assumed_blockchain_size` (`=240` in `chainparams.cpp`).
If the user launches the first time with `-prune=...` then we disable the check box and display the correct size (rounded to GB):

The 2 GB default matches the settings default. The user can't change it in the intro screen, but can change it later. I'm tempted to increase that default to 10 GB, and then have the intro screen reduce it if space is really tight.
Tips for testing:
* move your existing data dir elsewhere
* wipe data dir at every restart (behavior is different if it exists)
* launch with `bitcoin-qt -resetguisettings -lang=en` (there's some space issues in different languages)
* fake your free space by changing `intro.cpp` line 90: `freeBytesAvailable = 5000000000; // 5 GB`
* try both testnet and mainnet, because settings are seperate. In particular note how step 7 in `GuiMain` switches where `QTSettings settings` points to; this had me thoroughly confused on testnet, because I was setting them too early.
ACKs for top commit:

Tested ACK 9924bce317
ryanofsky:
utACK 9924bce317. The changes are very logical, and implement the feature in a clean that way that doesn't add a lot of complication and shouldn't interfere with future improvements. I looked at Luke's branch too, and I think there's also a lot of great stuff there that seems fully compatible with this change.
