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.
Fix issue #717 t
Fix issue #717 where if addrman is starved of addresses (e.g. on testnet)
the Select_() function will loop endlessly trying to find an address,
and therefore eat up 100% cpu time on the 'opencon' thread.
Solution is to (1) add a delay to the loop and (2) restrict the number
of attempts to find an address. On exiting the loop, we return
to an outer loop in net.cpp which will sleep, add seed nodes and
calculate new addresses.
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.
Adds several unittests for CAddrMan and CAddrInfo.
Increases the accuracy of addrman tests.
Removes non-determinism in tests by overriding the random number generator.
Extracts testing code from addrman class to test class.

Implement and integrate new Incremental Merkle Tree
This supersedes #823.
----
This is an implementation of a new incremental merkle tree with
* no memory safety issues
* a more sensible internal design
* better space efficiency (tree representation, witnessing)
* simpler API
It is intended that this tracks the behavior of the previous tree, which it does, as verified by tests. I even wrote a little circuit for testing that all the paths work.
This PR also integrates the tree into the codebase and deprecates the old tree in almost all of our code. (I left it alone in `zerocashTest` but everything else has been changed.)
This change is compatible with the testnet but you will need to clear your *local* blockchain data out since the serialized representation of the merkle tree is now different.
Closes#517, Closes#519, Closes#591, Closes#460, Closes#473
