Pull request description:
This updates leveldb to currently newest upstream commit 0c40829872:
- CRC32C hardware acceleration is now an external library [crc32c](https://github.com/google/crc32c). This adds acceleration on ARM, and should be faster on x86 because of using prefetch. It also makes it easy to support similar instruction sets on other platforms in the future.
- Thread handling uses C++11, instead of platform specific code.
- Native windows environment was added. No need to maintain our own hacky one, anymore.
- Upstream now builds using CMake. This doesn't mean we need to use that (phew), but internal configuration changed to a a series of checks, instead of OS profiles. This means the blanket error "Cannot build leveldb for $host. Please file a bug report' is removed.
All changes: a53934a3ae...0c40829872
Pretty much all our changes have been subsumed by upstream, so we figured it was cleaner to start over with a new branch from upstream with the still-relevant patches applied: https://github.com/bitcoin-core/leveldb/tree/bitcoin-fork-new
There's quite some testing to be done (see below). See https://github.com/bitcoin-core/leveldb/issues/25 and https://github.com/bitcoin-core/leveldb/pull/26 for more history and context.
TODO:
- [x] Subtree `crc32c`
- [x] Make linters happy about crc32 subtree
- [x] Integrate `crc32c` library into build system
- [x] MSVC build system

fa5d709fb266c97d4db15006bf855e887a6c123b ci: Move wrap-qemu into separate script (MarcoFalke)
Pull request description:
Now that the ci system no longer propagates files from the docker container back to the host, the wrap-qemu script is broken.
To fix it, every statement in the script needs to be executed in the docker (with `DOCKER_EXEC`). Instead of juggling with triple escape sequences like `\\\"`, just move the script to a separate file and call it with `DOCKER_EXEC`.
Also, fix a bunch of other bugs that prevent running the ci system in qemu
See the `ci/README.md` on how to test. TLDR: Can be tested with (replace `arm` with `s390x` to run the s390x build):
```
FILE_ENV="./ci/test/00_setup_env_arm.sh" MAKEJOBS="-j9" ./ci/test_run_all.sh
```

ef63f5fc1136ad2a2cd080d44142a2ee3945c238 ci: Combine 32-bit build with CentOS 7 build (Sebastian Falbesoner)
Pull request description:
Combines the CentOS build with the 32-bit (i686) build to avoid Travis bottlenecks, as suggested in #17757 by MarcoFalke. This keeps most of the properties of the 32-bit build (dash as config shell, building QT5 GUI) and just builds it with depends inside the CentOS docker container.
Making the depends in `05_before_script.sh` with unset config shell (`CONFIG_SHELL=`)
6196e93001/ci/test/05_before_script.sh (L28)
caused problems for building the library libevent (resulting in a Makefile with no shell set (`SHELL=`)), that's why I set it explicitely to `/bin/bash` if we have a CentOS Docker container.
A Travis output of this 32-bit CentOS build can be seen here: https://travis-ci.org/theStack/bitcoin/jobs/634472394 (has been restarted once due to too long build time and appearance of the `CACHE_ERR_MSG`).
For anyone wanting to verify the outputs, I found these instructions useful to reproduce a Travis build locally: https://github.com/erdc/proteus/wiki/Replicating-the-TravisCI-Environment-on-your-Local-Machine (steps 1-3). In this case it's a bit tricky since you run Docker inside Docker -- within the Travis Docker container, the CentOS Docker container is created. To make this possible, the Docker socket has to be exposed to the Travis container via bind-mounting (`docker run -v /var/run/docker.sock:/var/run/docker.sock ...`), as suggested in https://stackoverflow.com/a/33003273.

7f3ae224685efaeb6fe714de90e8871d12e55f34 ci: Add CentOS 7 build (Hennadii Stepanov)
Pull request description:
Arguably, CentOS is the most conservative distro of all the popular ones. Thus, it could be a good way to check the Bitcoin Core compatibility with aged dependencies.
Currently, CentOS 7 has:
- Berkeley DB == 4.8.30
- Boost == 1.53.0
- GCC == 4.8.5
- libevent == 2.0.21 < minimum required [2.0.22](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md), but tests passed
- MiniUPnPc == 2.0
- Python == 3.6.8
- qrencode == 3.4.1
- Qt == 5.9.7
- ZeroMQ == 4.1.4
~Please note that this PR is based on the bugfix #17634.~
Also trusty build has been removed for the following reasons:
- https://github.com/bitcoin/bitcoin/issues/17628#issuecomment-559448201:
> Maybe it'd make sense to replace Ubuntu Trusty with Centos 7 as the "check ancient backward compatibililty" Travis run. It's supported until 2024, apparently.
- https://github.com/bitcoin/bitcoin/pull/17635#discussion_r354811792:
> Our travis is currently running at its limit and this doesn't seem like it is adding a lot new coverage compared to the other builds.

Pull request description:
Changes in #12048 cause a compilation error in Arena::walk() when
ARENA_DEBUG is defined. Specifically, Arena's chunks_free map was
changed to have a different value type.
Additionally, missing includes cause other compilation errors when
ARENA_DEBUG is defined.
Reproduced with:
make CPPFLAGS=-DARENA_DEBUG

The definition and uses of Arena::walk() are compiled only if
ARENA_DEBUG is defined. Configure Travis to define ARENA_DEBUG so
compilation errors do not go unnoticed.
