The SDK now exposes UAs primarily, with additional methods for obtaining
corresponding Sapling and transparent addresses for legacy compatibility.
The `Account` DAO is also fixed to use the migrated `accounts` table format.
The demo app now shows the current UA and the legacy Sapling and transparent
addresses.
Closeszcash/zcash-android-wallet-sdk#677.
We need the transparent account privkey in order to be able to derive
the secret key for any leaf transparent address under the ZIP 316
diversified address tree.
UnifiedViewingKey had a bug that made it incompatible with ZIP 316.
For compatibility with the current `zcash/librustzcash` revision we use
a temporary fake UFVK encoding that stores sufficient information to use
the current APIs, and a superset of the actual ZIP 316 FVK information.
`decrypt_and_store_transaction` internally serialized transactions, but
the previous commit only added parsing support. Fortunately we already
have the transaction bytes, so to handle this in the short term we can
just pass them through.
Once we have migrated the SDK to latest `zcash/librustzcash` the API
will return to its previous form.
This doesn't affect Sapling note detection (which uses Compact Blocks),
but enables the enhancement logic to decrypt and store the corresponding
transactions for displaying memo fields.
The binary itself was removed in zcash/zcash-android-wallet-sdk#263 but
the `Cargo.toml` was not updated. This didn't affect the SDK itself
because by default it didn't build with the `updater` feature flag.
Move SDK from the root gradle project to its own Gradle module
Move the demo app to be a peer of the SDK
This will simplify integration with CI on Bitrise.
