Prior to this change, the recipient of a sent transaction would always
be shown as the protocol-level address, instead of any unified address
intended as the recipient. Now, instead of reencoding the recipient
address, we use the original `ZcashAddress` value from the payment
request.
We plan to also introduce a similar flag to gate access to Sapling
functionality. Since introduction of Orchard functionality is still
nascent, it's the correct time to introduce this isolation, before
there's more functionality that needs to be isolated in this fashion.
Public methods for mutation of these fields have been provided that
perform checking for overflow of the valid monetary range as part
of their operation.
Under normal usage conditions, the `transactions` table is not currently
populated for transactions involving transparent UTXOs, and so this join
was always resulting in transparent UTXO information being filtered out
from the transaction history.
Fixes [zcash/ZcashLightClientKit#1271]
This also removes the zcash_client_sqlite-specific database
initialization procedures in favor of a standardized approach using the
methods available via the data access API.
Previously this was not clearly specified, and the implementations in
`zcash_client_sqlite` behaved similarly to when `from_height = None`.

In general, it is preferable to use globally relevant identifiers where
possible. This PR removes the `WalletRead::TxRef` associated type in
favor of using `TxId` directly for the transaction identifier, and
restricts the use of the `NoteRef` type to those scenarios where the
result of one query is intended to be used directly as the input to
another query.
Closes#834
The `add_checkpoint` method is intended to be idempotent. In the case
that we add a checkpoint at an already-checkpointed block height, we
should only raise an error in the case that the note commitment tree
position or the set of notes spent in the checkpointed block has
changed.
In preparation for out-of-order range-based scanning, it is necessary
to ensure that the size of the Sapling note commitment tree is carried
along through the scan process and that stored blocks are always
persisted with the updated note commitment tree size.
