bellman: add VerificationError (#254) 
* bellman: add VerificationError

This adds a distinct VerificationError type to the crate and changes
`verify_proof` to return `Result<(), VerificationError>` rather than
`Result<bool, SynthesisError>`.  This is significantly safer, because it avoids
the need to mix pattern-matching logic with boolean logic (the cause of
RUSTSEC-2019-0004).

* Rename VerificationError variants per review comments.

* Add missing Clone impl to VerificationError.

Jack Grigg c921cfcf97 zcash_proofs: Add LocalProver::bundled 
Requires the bundled-prover feature, which enables the
wagyu-zcash-parameters crate and adds around 50 MiB to the overall
binary size. That crate bundles the same Sapling parameter files we
normally obtain from disk, so we constrain them to match the same
hard-coded hashes.

with per-transaction granularity.
