Joe Bryan 50782bd1c9 Merge branch 'research-constitution' into release-candidate
* research-constitution: (120 commits)
  removes obsolete doccords-style comments
  Revert "fixy uno~by, other vor-based code duplication"
  Implement argon2.
  Use face over lark when available.
  Implement blake2b.
  Use ++rep over ++can when we can
  Use ++rev over ++swp, for safety.
  Clean up base58 en/decoding
  Rename secp point serialization arms
  Add HMAC-SHA1
  Put +=byts to use
  Restructure and complete BIP32 core
  Fix bug in RIPEMD-160 implementation.
  BIP32 key derivation logic. Messy, in dire need of restructuring.
  Fix bug in HMAC implementation.
  SHA-1 re-implementation, can account for leading zeroes.
  Converting points on curve to un/compressed numbers.
  RIPEMD-160 implementation.
  Start work on BIP32 support. Library file includes wrappers for the SHA family to make it take and produce sane byte order data, and a new HMAC implementation that depends on it. Also includes @belisarius222's secp256k1 implementation, plus experimental (and broken) support for other secp variants.
  Add ++rev to bit arithmetic, for reversing block order while accounting for leading zeroes.
