Add sapling::NullifierDerivingKey newtype.
...
Nullifier computation only requires the nullifier deriving key,
not the entire Sapling viewing key. This separation of concerns
will be needed for batch decryption when wallet-internal keys
will need to be considered.

zcash_client_backend: Migrate to correct ZIP 316 UFVK encoding
...
We also add support for parsing Orchard full viewing keys from encoded
UFVKs (rather than treating them as unknown). `UnifiedSpendingKey` still
does not have Orchard support, so `UnifiedFullViewingKey`s will be
generated without Orchard components.

zcash_client_backend: Fix `UnifiedFullViewingKey` Sapling item type
...
Per ZIP 316, the Sapling FVK Encoding only includes `(ak, nk, ovk, dk)`
which is a subset of the Sapling `ExtendedFullViewingKey`. We therefore
need to use `DiversifiableFullViewingKey` inside `UnifiedFullViewingKey`
in order to make it parseable from the UFVK string encoding.
`zcash_client_sqlite::wallet::get_extended_full_viewing_keys` has been
removed as a consequence of this change: we can no longer reconstruct
the correct `ExtendedFullViewingKey` from the `UnifiedFullViewingKey`.

zcash_client_backend: Remove account from `UnifiedFullViewingKey`
...
The account number is not stored in the ZIP 316 UFVK encoding, and in
general won't necessarily be known (e.g. if a UFVK is being imported
into a wallet).
`zcash_client_sqlite::wallet::init::init_accounts_table` reverts to its
previous behaviour of requiring the provided `&[UnifiedFullViewingKey]`
to be indexed by account number.

zcash_client_backend: Use correct output index for t-addr recipients
...
`create_spend_to_address` was originally written only for sending to
Sapling addresses. It was later amended to support sending to
transparent addresses, but the assumption about there being a Sapling
output was not removed. This was not an issue for most transactions
because there would be change, but in the case of a z->t transaction
with no change, `create_spend_to_address` would reliably panic.
This commit fixes the bug by setting the output index for transparent
recipients to 0. The `output_index` field of `SentTransaction` is also
documented to correctly reflect its dependency on the type of
`recipient_address`.

Remove Default impl from MemoBytes
...
Memo fields have two ways to encode an empty memo:
- 0xF6 followed by all-zeroes, encoding "there is no memo".
- All-zeroes, encoding the empty UTF-8 string.
In almost all cases you want the former, but users thinking about byte
slices may expect MemoBytes::default() to result in the latter. To
ensure clarity, we now require calling either MemoBytes::default() or
MemoBytes::from_bytes(&[]) to be explicit.
No such confusion exists for the Memo enum, because the two types are
visibly separated as different enum cases, and Memo::Empty makes sense
as the default.

Split memo-handling into MemoBytes struct and Memo enum
...
The MemoBytes struct is a minimal wrapper around the memo bytes, and only
imposes the existence of null-padding for shorter memos. The only error
case is attempting to construct a memo that is too long. MemoBytes is
guaranteed to be round-trip encodable (modulo null padding).
The Memo enum implements the additional memo rules defined in ZIP 302,
interpreting the contents of a memo (for example, parsing it as text).

zcash_client_sqlite: Read rcm correctly from data DB after Canopy
...
ZIP 212 alters the note plaintext to store a seed from which rcm is
derived, rather than storing rcm directly. In the mobile SDKs we only
need rcm, so for post-ZIP 212 notes, we derive rcm from the seed and
store rcm in the data DB.
However, when selecting notes to spend, `create_to_address` was using the
transaction's target height to determine if Canopy is active, and parsing
the rcm value as the seed if so. This effectively applied a seed->rcm
derivation to all selected notes' rcms once Canopy activated on the
chain. As a result, the note commitments were incorrect, and thus the
anchors derived from the witness paths were also incorrect. This caused
two kinds of observed failures:
- If more than one note was selected, the builder would fail with
"anchor mismatch", as the note commitments would be effectively
randomised, causing the derived anchors to also randomise.
- If a single note was selected, the transaction would be built using
the randomised anchor, and then rejected when sent to the network.
The fix is to "pretend" in `create_to_address` that all notes are
pre-ZIP 212 notes. This works fine because we never need to serialize
back to the note plaintext while spending a note.
