Improve joinsplit diagnostics

I don't advocate merging this for the hotfix release (to fix #1779) but this PR can be used to diagnose the real issue and should be merged ASAP afterward.

~I still need to add tests for `last()` and `element()` though.~ Done.

Deallocate the public parameters during Shutdown.

This also has it deallocated in `GenerateParams` and `test_bitcoin`. The virtual destructor probably isn't necessary but I added it just in case we need it some other time.

6caacc892e Auto merge of #1058 - ebfull:coin-cache, r=ebfull 
Flush to disk more consistently by accounting memory usage of serials/anchors in cache.

Closes #626.

It's important that this at least *approximates* the memory usage, so that we flush the cache to disk as expected. It's okay that we overestimate. The serials are stored in keys in the `boost::unordered_map`, so we can simply use that map's `DynamicMemoryUsage`. The anchors are another story.

62a2d12672 Auto merge of #1026 - ebfull:address-serialization, r=ebfull 
Zcash address encoding

We need to encode Zcash addresses so they aren't as large and unweildy. We're using Base58Check just like upstream does, and to ensure the first character is "z" in our addresses we must use two bytes for the version string. Two bytes gives us an extra character for free, so this PR targets the beginning of addresses to have "zc".

```
$ ./src/zcash-cli zcrawkeygen
{
    "zcaddress" : "tnvaj4ZbZG83tj4RwZcFeLgJoSt8nw1ZvSCG8EMyowAsXTQgJPat77Y43BVdVCrwrbLy7GG9msJDYdn5hmreHmkXAkX17hb",
    "zcsecretkey" : "SKzkxCRWvscKnroSFyhCqhY332KcDMH4LLNdK2TsSvbmr3CGAB8B",
    "zcviewingkey" : "10aa74046f31cbe5eaa8965d1e104853234c3d6c6e45f9c497ca3a025d159755"
}
```

This PR also encodes the spending keys with a prefix that targets "SK". The spec needs to be updated with these changes.

Testnet addresses will start with "tn".

Closes #572
