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.
Memos may be absent for both sent and received notes in cases where only
compact block information has been used to populate the wallet database.
This fixes a potential crash in the case that we attempt to decode a
SQLite `NULL` as a byte array.

(cherry picked from commit d99b4d4d6e)
This allows callers to validate smaller intervals of the given
`BlockSourceT` shortening processing times of the function call at the
expense of obtaining a partial result on a given section of interest of
the block source.
`params: &ParamsT` has been removed from the arguments since they were
only needed to fall back to `sapling_activation_height` when `None` as
passed as the `validate_from` argument. Passing `None` as validation
start point on a pre-populated `block_source` would result in an error
`ChainError::block_height_discontinuity(sapling_activation_height - 1, current_height)`
With this new API callers must specify a concrete `validate_from`
argument and assume that `validate_chain` will not take any default
fallbacks to chain `ParamsT`.
The addition of a `limit` to the chain validation function changes the
meaning of its successful output, being now a `BlockHeight, BlockHash)`
tuple indicating the block height and block hash up to which the chain
as been validated on its continuity of heights and hashes. Callers
providing a `limit` aregument are responsible of subsequent calls to
`validate_chain()` to complete validating the remaining blocks stored on
the `block_source`.
