10d2c57c0d Replace calls to GetHash() with GetTxid() for transaction objects. 
Where the caller intends to receive a transaction id and not a double
SHA256 hash.

6793168a2e Auto merge of #1017 - ebfull:coinbase-must-be-protected, r=ebfull 
Enforce that coinbases must be protected

This PR forces miners to place their funds in the private value transfer system, making "transparent coins" opt-in for users, and increasing privacy for all participants on a systemic level.

Closes #101.

19769ba6c5 Auto merge of #976 - ebfull:implement-joinsplit-signatures, r=ebfull 
Signing pours with ed25519

This is an alternative to #964 which uses ed25519 instead of secp256k1, and avoids the separate hash for fitting the public key into the `h_sig` block. It's based on @defuse's work in that branch.

Closes #808.

f3ffa3d27f Implementation of Founders' Reward.

the genesis block, must contain an output which sends 20% of the block
subsidy value to a scriptPubKey `FOUNDERS_REWARD_SCRIPT`.

fdda3c5085 Use Equihash for Proof-of-Work 
The main and test networks are configured to use parameters that are currently
low-memory but usable with the basic solver; they will be increased once the
solver is optimised. The regtest network is configured to have extremely low
memory usage for speed.

Note that Bitcoin's double-hasher is used for the difficulty check. This does
not match the paper, but is simpler than changing the block header
serialization. Single hashing is kept for the EquiHash solver because there is
no requirement on execution time there, only on memory usage.
