Jack Grigg 79006ecbdf Unify Sapling tree depth constants 
When sapling-crypto is refactored, the zcash_primitives::sapling
constant would become the canonical one.

Jack Grigg e67560b154 Document merkle_tree module 2019-07-10 13:53:22 -04:00
Jack Grigg b9cea33804 Move merkle_tree::Node into sapling module 
This makes the merkle_tree module properly generic over the tree hash.
It still hard-codes a depth 32 tree, because Rust doesn't yet support
generic sizes, and we are unlikely to need to alter the tree depth in
future circuit changes.

Jack Grigg 060977fe54 Return edwards::Point from sapling_ka_agree 
This matches how sapling_ka_agree and kdf_sapling are defined in the
protocol spec. kdf_sapling also now takes ownership of dhsecret to
discourage use of the sapling_ka_agree output elsewhere.

Jack Grigg 6dcb4040af Switch to crypto_api_chachapoly crate 
This crate exposes both the ChaCha20Poly1305 IETF construction, and the
underlying ChaCha20 IETF primitive, removing the need for depending on
our own fork of the previous chacha20-poly1305-aead crate.
