c9a2eea5e2 Auto merge of #905 - ebfull:test-suite-fixes, r=ebfull 
Run `zcash-gtest` in `make check` and fix performance tests.

* gtest tests weren't being run by make check
* performance tests were broken
* We need to automatically upload graphs of performance, [see this PR](https://github.com/Electric-Coin-Company/bbotzc/pull/15).
* Moves zerocash tests into `zcash`'s full test suite, we're removing them anyway later and it'd be nice to remove them in the PR instead of from buildbot

92f3c6082a Auto merge of #889 - ebfull:new-imt-redux, r=ebfull 
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
