c82d15b6d1 depends: Do not force Precompiled Headers (PCH) for building Qt on Linux (Hennadii Stepanov)

Pull request description:

  On CentOS 8 (Cirrus CI job) the forced `-pch` option breaks Qt build.

  Removing `-pch` option does not affect build time for other systems:

Merge #20419: build: set minimum supported macOS to 10.14
a52ecc936a build: set minimum supported macOS to 10.14 (fanquake)

Pull request description:

  This is a requirement for C++17 support. See my comments [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-643722538):

  > You cannot use std::get with std::variant on macOS < 10.14, because Apples libc++ doesn't support the std::bad_variant_access exception. [Relevant comment](https://github.com/bitcoin/bitcoin/pull/19183#discussion_r439794318) in #19183.

  > While we could work around this in our own code, using std::get_if, this would still be a problem for 3rd-party dependencies.

  > I've been testing Qt 5.15LTS (we'll have to enable C++17 in qt, and may upgrade to a newer version at the same time), and you can't enable -std c++17, while targeting a macOS deployment version < 10.14, configuring will fail. They are making use of std::get with std::variant throughout their cocoa code.

  We would have to had to have bumped to at least 10.13 in any case, as Qt 5.15 (#19716) [requires 10.13+](https://doc.qt.io/qt-5/supported-platforms.html).

Merge #19504: Bump minimum python version to 3.6
97c738ff1b [tests] Recommend f-strings for formatting, update feature_block to use them (Anthony Towns)
8ae9d314e9 Bump minimum python version to 3.6 (Anthony Towns)

Pull request description:

  Python 3.5 has reached [end-of-life](https://devguide.python.org/#status-of-python-branches) as of September 2020, and 3.6 has some moderately nice [features](https://docs.python.org/3/whatsnew/3.6.html):

  - `f'x = {x}'` as an alternative to `'x = {}'.format(x)` format strings (cf https://github.com/bitcoin/bitcoin/pull/13718#issuecomment-406591027)
  - underscore separators for large numbers, like `1_234_567`
  - improvements to async
  - improvements to typing module

  Note that 3.6 is not available in xenial (16.04), but is available in bionic (18.04), while focal (20.04) has 3.8. CentOS 7 and 8 have 3.6.8, Debian stable has 3.7.3, and [gentoo and arch already had 3.6 and 3.7 in 2018](https://github.com/bitcoin/bitcoin/pull/14954#issuecomment-447118707).

Pull request description:

  This is an implementation of the Schnorr/taproot consensus rules proposed by BIPs [340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki), [341](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki), and [342](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki).

  See the list of commits [below](https://github.com/bitcoin/bitcoin/pull/19953#issuecomment-691815830). No signing or wallet support of any kind is included, as testing is done entirely through the Python test framework.

  This is a successor to https://github.com/bitcoin/bitcoin/pull/17977 (see discussion following [this comment](https://github.com/bitcoin/bitcoin/pull/17977#issuecomment-682285983)), and will have further changes squashed/rebased. The history of this PR can be found in #19997.

Merge #20072: ci: Build Arm64 on Travis without functional tests
33df8d46bb ci: Build Arm64 on Travis without functional tests (Fabian Jahr)

Pull request description:

  The Travis Arm64 env is a pretty big PITA for quite a while now. It simply seems to time out due to a lack of resources as far as I can tell from my research into the matter.

  I have reported the issue in August and received no response: https://travis-ci.community/t/arm64-failing-without-message/9775. Others have complained about similar issues with Arm64 over the past year. The explanation for this is probably that this env is still considered to be in beta: https://docs.travis-ci.com/user/multi-cpu-architectures.

  Considering the high frequency of failures (I didn't run any numbers, just based on my personal observations) and the beta status I would suggest that we shorten the runtime by removing part of the test suite until the env is more stable. I would suggest removing functional tests since it should help for sure but maybe there are other ideas.

fa0f6c58c1 Revert "Fix link error with --enable-debug" (MarcoFalke)

Pull request description:

  This reverts a hacky workaround from commit b83cc0f, which only happens to work due to compiler optimizations. Then, it actually fixes the linker error.

  The underlying problem is that the wallet includes symbols from the server (ui_interface), which usually results in linker failures. Though, in this specific case the linker failures have not been observed (unless `-O0`) because our compilers were smart enough to strip unused symbols.

  Fix the underlying problem by creating a new header-only with the needed symbol and move ui_interface to node to clarify that this is part of libbitcoin_server.

My hasty assumption is that this will fix it. In any case, all other instances of `TEST_RUNNER_EXTRA` seem to have moved out of `.travis.yml` and into the different CI configurations.

    ACK fa74a54fad - the test failure here is a different issue, and the problem referenced by this PR hasn't occurred, so I think this can be merged. It's also fixing the use of `--factor` which was replaced in #18986.

Merge #19348: test: Bump linter versions
39d526bde4 test: Bump linter versions (Duncan Dean)

Pull request description:

  As per #19346, `mypy==0.700` was incompatible with Python 3.8.

  I've bumped the versions of all the linters to their latest stable versions.

  Checked with both Python 3.7 and 3.8 and everything still seems to work fine.

b3394ab235 contrib: macdeploy: Correctly generate macOS SDK (Carl Dong)

Pull request description:

  This PR achieves 3 main things:
  1. It simplifies the macOS SDK generation by putting the logic inside a (semi-)portable python3 script `gen-sdk`
  2. It transitions us to using `libc++` headers extracted from the `Xcode.app`, which is more correct as those headers better match the `.tbd` library stubs we use from the `MacOSX.sdk` (located under the same `Xcode.app`). Previously, we used `libc++` headers copied from our downloaded, pinned clang (see `native_cctools.mk`).
  3. It bumps the macOS toolchain in a way that fulfills all of the following constraints:
      1. The new SDK should support compiling with C++17 (our current one doesn't)
      2. The new toolchain should not change our minimum supported macOS version (`-mmacosx-version-min`)
      3. The new toolchain should expect to use a version of `cctools` that is supported by https://github.com/tpoechtrager/cctools-port

  For the constraints in (3), you can reference [this chart](https://en.wikipedia.org/wiki/Xcode#Xcode_7.0_-_11.x_(since_Free_On-Device_Development)) to see that the newest toolchain we can use with our `cctools-port` is `11.3.1`, and the rest of the constraints were tested with local builds.

  #### But [the other Wikipedia chart](https://en.wikipedia.org/wiki/Xcode#Xcode_11.x_(since_SwiftUI_framework)) says that the "min macOS to run" for Xcode 11.3.1 is 10.14.4, doesn't that violate constraint (ii)?

  This confused me at first too, but the "min macOS to run" is for the Xcode.app App itself. The SDK still supports 10.12, as evident in a few plist files and as proven through local builds.

  #### Why bundle all of this together in a single PR?

  We need (1) and (2) together, because if we don't, manually adding the `libc++` headers and writing that out in a `README.md` is going to result in a lot of user error, so it's great to have these together to be more correct and also make it easier on the user at the same time.

  We need (3) together with everything else because bumping (or in the case of (1), renaming) the SDK requires some human coordination and may break some builds. And since it's not that complicated a change, it makes sense to do it together with the rest.
