ZCProof was too general. pubKeyHash was actually the JoinSplit pubkey
itself.

e5eab182b5 Use boost::variant to represent shielded addresses and keys 
libzcash::PaymentAddress has been renamed to libzcash::SproutPaymentAddress,
and a new typedef boost::variant is now libzcash::PaymentAddress. Similarly
for ViewingKey and SpendingKey.

A new class InvalidEncoding is introduced as the default boost::variant
option for each address and key type; it is used during decoding instead
of boost::optional.

All address and key storage functions in the wallet have been modified to
refer specifically to the Sprout types, as they are used very precisely.
In most other cases, the more general type is leveraged as much as possible,
and we convert to the Sprout type when necessary. This will be subsequently
wrapped in, or replaced with, context-specific functions once Sapling
types are implemented.

Sapling merkle tree implementation

Closes #3056.

Please also review https://github.com/zcash/librustzcash/pull/8

This PR:

1. Introduces ZCSaplingIncrementalMerkleTree using Pedersen hashes.
2. Adds support for Sapling anchors into consensus rules. (Adds commitments, checks anchors are correct, handles block (dis)connects, etc.)
3. Handles mempool eviction for obsolete anchors.
4. Enforces correctness of block's Sapling root field
5. Changes miner to correctly apply the Sapling root to the block header
6. Handles mempool consistency checks for anchors

Closes #3194.  Lays foundation for introduction of Sapling notes through refactoring and creation of a class hierarchy for Sprout notes.  This PR updates some tests, but otherwise is a no-op.
