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 )
