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

Repository Tools

Developer tools

Specific tools for developers working on this repository. Additional tools, including the github-merge.py script, are available in the maintainer-tools repository.

Verify-Commits

Tool to verify that every merge commit was signed by a developer using the github-merge.py script.

Linearize

Construct a linear, no-fork, best version of the blockchain.

Qos

A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Bitcoin network. This means one can have an always-on bitcoind instance running, and another local bitcoind/bitcoin-qt instance which connects to this node and receives blocks from it.

Seeds

Utility to generate the pnSeed[] array that is compiled into the client.

Build Tools and Keys

Packaging

The Debian subfolder contains the copyright file.

All other packaging related files can be found in the bitcoin-core/packaging repository.

Gitian-descriptors

Files used during the gitian build process. For more information about gitian, see the the Bitcoin Core documentation repository.

Gitian-keys

PGP keys used for signing Bitcoin Core Gitian release results.

MacDeploy

Scripts and notes for Mac builds.

Gitian-build

Script for running full Gitian builds.

Test and Verify Tools

TestGen

Utilities to generate test vectors for the data-driven Bitcoin tests.

Verify Binaries

This script attempts to download and verify the signature file SHA256SUMS.asc from bitcoin.org.
