Pull request description:

  This implements the compact block filter construction in [BIP 158](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki). The code is not used anywhere in the Bitcoin Core code base yet. The next step towards [BIP 157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) support would be to create an indexing module similar to `TxIndex` that constructs the basic and extended filters for each validated block.

  ### Filter Sizes

  [Here](https://gateway.ipfs.io/ipfs/QmRqaAAQZ5ZX5eqxP7J2R1MzFrc2WDdKSWJEKtQzyawqog) is a CSV of filter sizes for blocks in the main chain.

  As you can see below, the ratio of filter size to block size drops after the first ~150,000 blocks:

  ![filter_sizes](https://user-images.githubusercontent.com/881253/42900589-299772d4-8a7e-11e8-886d-0d4f3f4fbe44.png)

  The reason for the relatively large filter sizes is that Golomb-coded sets only achieve good compression with a sufficient number of elements. Empirically, the average element size with 100 elements is 14% larger than with 10,000 elements.

  The ratio of filter size to block size is computed without witness data for basic filters. Here is a summary table of filter size ratios *for blocks after height 150,000*:

  | Stat | Filter Type |
  |-------|--------------|
  | Weighted Size Ratio Mean | 0.0198 |
  | Size Ratio Mean | 0.0224 |
  | Size Ratio Std Deviation | 0.0202 |
  | Mean Element Size (bits) | 21.145 |
  | Approx Theoretical Min Element Size (bits) | 21.025 |

64fb0ac Declare single-argument (non-converting) constructors "explicit" (practicalswift)

Pull request description:

  Declare single-argument (non-converting) constructors `explicit`.

  In order to avoid unintended implicit conversions.

  For a more thorough discussion, see ["C.46: By default, declare single-argument constructors explicit"](http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c46-by-default-declare-single-argument-constructors-explicit) in the C++ Core Guidelines (Stroustrup & Sutter).
