Begin writing btls, a Haskell crypto and TLS library using BoringSSL

So far, btls provides SHA-224, SHA-256, SHA-384, and SHA-512 algorithms.
To do that, I

  - vendor BoringSSL and create a custom `Setup.hs` to build it,

  - wrap a number of functions and values from BoringSSL's EVP
    subsystem, and

  - implement the four SHA-2 algorithms using the wrapped routines.

I provide conformance tests incorporating the official NIST example
vectors and the vectors used in the Go SHA-2 test suite. The tests also
use SmallCheck to compare btls’s SHA-2 implementations with those
provided by the system’s Coreutils and openssl(1) installations.
