Kris Nuttycombe 48f226f8b5 Move decoding errors to sqlite crate.
Also move dependency on params out of wallet read/write methods.
The result is cleaner because these parameters are only required
for backend-specific encoding and decoding operations.

Jack Grigg 10f5dddb79 zcash_client_backend: Fix testnet bug in diversify-address example
I misunderstood the meanings of Err(_) vs Ok(None), which indicates that
we need to refactor this API! In the meantime, this enables the example
to work with testnet Sapling viewing keys.

Kris Nuttycombe cd2729bbd0 Move 'create_spend_to_address' to wallet backend.

of now simplifying the error situation a bit.

Kris Nuttycombe 1ad9294933 Remove static determination of network state.
In the interest of making the library usable for both
testnet and mainnet without recompilation, static resolution
of network parameters has been replaced with a parameter passed
to the relevant functions. This also moves addres prefix constants
into the network parameters.

Jack Grigg 192db29a25 Take epk as a jubjub::ExtendedPoint for note decryption
We don't need to check if epk is in the prime-order subgroup before we
trial-decrypt, which saves a third of the cost of trial-decrypting
outputs that are not ours.

Jack Grigg 9377b78b35
Panic if spending_key is given a seed shorter than 32 bytes
This enforces the MUST requirement in ZIP 32. A panic is used instead of
an error because this should be considered an implementation error.
Ideally the type system would prevent this from occurring at all.
