libzcash and new zkSNARK circuit implementation

This PR completes [`libzcash`](https://github.com/zcash/zcash/tree/zc.v0.11.2.latest/src/zcash), the implementation of the [Zcash protocol specification](9bb4410e45/protocol/protocol.pdf) and replacement of [`libzerocash`](https://github.com/Zerocash/libzerocash), our old Zerocash protocol implementation. The new spec comes with some improvements to security and terminology, with minimal differences from the original academic design.

This implementation includes:

* A rewrite of the zkSNARK circuit for `JoinSplit` operations. This rewrite is cleaner, broken up into separate gadgets, easier to audit and review, and fixes some security bugs. (Closes #822, Closes #809, Closes #500, Closes #854)
* A minimal API for interacting with `JoinSplit`s and surrounding primitives. This PR removes almost twice as much code as it introduces. (Closes #877, Closes #315, Closes #824, Closes #798, Closes #707, Closes #512, Closes #247, Closes #128, Closes #514)

b0f75847ea 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
calcualte new addresses.
