6170ec5d3a Do not query all DNS seed at once (Pieter Wuille)
Pull request description:
Before this PR, when we don't have enough connections after 11 seconds, we proceed to query all DNS seeds in a fixed order, loading responses from all of them.
Change this to to only query three randomly-selected DNS seed. If 11 seconds later we still don't have enough connections, try again with another one, and so on.
This reduces the amount of information DNS seeds can observe about the requesters by spreading the load over all of them.

utACK 6170ec5d3a - I think the risk of a single seeder codebase is orthogonal to this PR. Such risks could also be interpreted differently (diversity could also increase the risk based on the threat model).

ACK 6170ec5d3a - Agree with the reasoning behind the change. Did some testing with and without `-forcednsseed` and/or a `peers.dat` and monitored the DNS activity.

fa69588537 test: Make PORT_MIN in test runner configurable (MarcoFalke)
Pull request description:
This is needed when some ports in the port range are used by other processes. Note that simply assigning the ports dynamically does not work:
* We spin up several nodes per test (each node gets its own port)
* We run several tests in parallel
So to avoid nodes from different tests colliding on ports, the port assignment must be deterministic (can not be dynamic).

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

6aab7649d3 doc: Fix whitespace errs in .md files, bitcoin.conf, Info.plist.in, and find_bdb48.m4 (Jon Layton)
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.
