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

README.md

This folder contains lint scripts.

check-doc.py

Check for missing documentation of command line options.

commit-script-check.sh

Verification of scripted diffs. Scripted diffs are only assumed to run on the latest LTS release of Ubuntu. Running them on other operating systems might require installing GNU tools, such as GNU sed.

git-subtree-check.sh

Run this script from the root of the repository to verify that a subtree matches the contents of the commit it claims to have been updated to.

To use, make sure that you have fetched the upstream repository branch in which the subtree is maintained:

Usage: git-subtree-check.sh DIR (COMMIT)

COMMIT may be omitted, in which case HEAD is used.

lint-all.sh

Calls other scripts with the lint- prefix.
