Michal Fousek 65d6347bcf [#778] Add swiflint config file only for tests
Closes #778

- .swiftlint.yml is now used to lint only the code of the SDK.
- .swiftlint_tests.yml is now used to lint only the code of the tests.
  This config disables rules that were previously disabled in the code
  in lot of tests.

Michal Fousek 1ec12269ae [#764] Stop using Notifications inside the SDK
Closes #764

- All notification that were previously sent from CompactBlockProcessor are now gone.
- `CompactBlockProcessor` now provides `eventStream` to communicate with `SDKSynchronizer`.
- Added `synchronizerStoredUTXOs` notification.
- Tests are updated to not use notifications anymore. Some tests there
  weren't working before are now fixed.
- Added `CompactBlockProcessorEventHandler` utility class. Previously
  expectations were subscribing to notifications. This class replaces
  this functionality. It subscribes to events from
  `CompactBlockProcessor` and fullfill expectations.

Michal Fousek 385c0a7195 [#746] Modularize GRPC related code
Closes #746

- `LightWalletGRPCService` is no longer public. `LightWalletService` is no longer public.
- `LightWalletGRPCService` shouldn't be used dicrectly. Use `LightWalletServiceFactory` to create instance of the service.
- Moved sending of `blockProcessorConnectivityStateChanged` notification to `Initilizer`.
- All the errors from GRPC are mapped to `LightWalletServiceError`. Handling of `GRPCStatus` in the SDK is no longer required.
- `Service` directory (that contains GRPC code) is moved to `Modules/Service`. We can put more code to `Modules/` if we decide
to modularize more code.

- [#790] Fix ShieldFundsTests

Closes #790
Removes comments on `ShieldFundsTests` since those issues have been fixed

Depends on zcash-light-client-ffi changes that adopt newer versions of
 librustzcash crates `zcash_primitives 0.10`, `zcash_client_backend 0.7`,
`zcash_proofs 0.10`, `zcash_client_sqlite 0.5.0`.

Also allows wallets to define a shielding_threshold and will set
foundations to customize minimum confirmations for balances, spends
and shielding operations.

**Test Bootstrapping**

- `ZcashCompactBlockDescriptor`: struct that holds functions to
describe blocks as filenames and compare those filenames

`ZcashCompactBlockDescriptor.live` has the actual implementation
but it can be replaced by mocks if needed on Tests

main implementations are held under `FSCompactBlockRepository.filenameDescription` and `FSCompactBlockRepository.filenameComparison` on a separate extention

`DirectoryListingProviders` provide two default implementations of listing a
directory deterministically. `FileManager` does not define a sorting and needs to be done in-memory by calling `.sorted()` on the resulting collection. If this
is a big toll on performance it can be changed to a POSIX implementation but
this is good for now.

`ZcashCompactBlockDescriptor` adds a `height` helper function to
turn a filename into the height of the block stored.

Implemented `func latestHeight() throws -> BlockHeight ` that
returns the blockheight by querying the cache directory in a sorted
fashion and getting the last value and turning the filename into a
`BlockHeight`

Added `Meta` struct to ZcashCompactBlock.

Tests implemented:
- `filterBlockFiles`
- `testClearTheCache`
- `testLatestHeightEmptyCacheThrows`
- `testLatestHeightEmptyCacheThrowsAsync`
- `testRewindEmptyCacheDoesNothing`
- `testRewindEmptyCacheDoesNothingAsync`
- `testWhenBlockIsStoredItFollowsTheDescribedFormat`
- `testWhenBlockIsStoredItFollowsTheFilenameConvention`
- `testGetLatestHeight`
- `testRewindDeletesTheRightBlocks` test
- `testPerformanceExample` test. This isn't a real performance test because the API doesn't work with async/await yet

adopts `shield_funds` shielding threshold parameter

Implements `initBlockMetadataDb` and fix tests
Renames dbCache parameter to `fsBlockDbRoot`. Builds but tests don't pass.
Removes cacheDb uses from code. Testing utilities still persist.
Added needed information in  MIGRATING and CHANGELOG.
Added helper to perform deletion of legacy db and creation a the
new file system backed cache.

Renames parameters and changes code where needed.
Network Constants turned into `enum` with static methods.
DeletelastDownloadedBlock helper from initializer
Removes CompactBlockStorage and CompactBlockEntity.
Implements `latestCachedBlockHeight` on rustbackend.

*Replaces dependencies on ZcashRustWelding with `FSMetadataStore`*

This allows the tests to not depend in a particular implementation
of either the MockRustBackend of or ZcashRustBackend. Also provides
a way to test errors properly and switch implementations of critical
areas like `writeBlocks`.

[#534] Use UnifiedSpendingKey for shielding and Spending

This commit implements the use of Unified Spending Keys for shielding
and spending as well as rolling Unified Addresses.

Users should obtain addresses by rolling them from the SDK.
USKs replace Sapling Extended Spending keys and TransparentAccountPrivKeys
when shielding or spending

Closes #534

Francisco Gindre 9b930391a4 [#384] Adopt Type Safe Memos in the FFI and SDK
Closes #384

This makes the SDK use the Memo and MemoBytes types across the FFI and the
public interface of the SDKSynchronizer. Addresses the comments by @defuse  on
issue https://github.com/zcash/ZcashLightClientKit/issues/378.
These changes depend on zcash-light-client-ffi repo changes managing
memos as byte arrays instead of string encoding of memos.

There are some compromises in terms of database representation of memos
and their exposure in transaction representing entities because we
wanted to avoid changing the database at this moment and be retro-
compatible with earlier versions and maintain deprecated APIs for wallets
to have time to adopt.

Memo and MemoBytes are WIP and subject to change. we are exploring
making Memo an opaque type based on a struct and drop the enum approach
to make the interface less throwing.

Fix: wrap new functions and deprecate old API. catch Memo errors

update get_sent and get_received memo functions from rust welding
point to branch in FFI repo

Francisco Gindre ed87a2781c [#461] Adopt a Type-Safe Keys and Addresses API
This PR creates data types for Addresses and Keys so that they are
not represented by Strings anymore. This avoids mistakenly use
the wrong keys because they are all alike for the type system.

New Protocols:
=============

StringEncoded -> Protocol that makes a type can be expressed in an
string-encoded fashion either for UI or Interchange purposes.

Undescribable -> A protocol that implements methods that override default
decriptions used by debuggers, loggers and event trackers to avoid types
conforming to it to be leaked to logs.

Deleted Protocols:
==================

UnifiedFullViewingKey --> turned into a struct.
UnifiedAddress --> turned into a struct

new Error Type:
================

````
enum KeyEncodingError: Error {
    case invalidEncoding
}
````

This error is thrown when an Address or Key type (addresses are public
keys in the end) can be decoded from their String representation,
typically upon initialization from a User input.

New Types:
=========

SaplingExtendedSpendingKey -> Type for Sapling Extended Full Viewing Keys
this type will be replaced with Unified Spending Keys soon.

SaplingExtendedFullViewingKey -> Extended Full Viewing Key for Sapling.
Maintains existing funcionality. Will be probably deprecated in favor of
UFVK.

TransparentAccountPrivKey -> Private key for transparent account. Used
only for shielding operations. Note: this will probably be deprecated soon.

UnifiedFullViewingKey -> Replaces the protocol that had the same name.

TransparentAddress -> Replaces a type alias with a struct

SaplingAddress --> Represents a Sapling receiver address. Comonly called zAddress. This address corresponds to the Zcash Sapling shielded pool.
Although this it is fully functional, we encourage developers to
choose `UnifiedAddress` before Sapling or Transparent ones.

UnifiedAddress -> Represents a UA. String-encodable and Equatable. Use of
UAs must be favored instead of individual receivers for different pools.
This type can't be decomposed into their Receiver types yet.

Recipient -> This represents all valid receiver types to be used as
inputs for outgoing transactions.

````
public enum Recipient: Equatable, StringEncoded {
    case transparent(TransparentAddress)
    case sapling(SaplingAddress)
    case unified(UnifiedAddress)
````

The wrapped concrete receiver is a valid receiver type.

Deleted Type Aliases:
=====================

The following aliases were deleted and turned into types
````
public typealias TransparentAddress = String
public typealias SaplingShieldedAddress = String

````

Changes to Derivation Tool
==========================

DerivationTool has been changed to accomodate this new types and
remove Strings whenever possible.

Changes to Synchronizer and CompactBlockProcessor
=================================================
Accordingly these to components have been modified to accept the
new types intead of strings when possible.

Changes to Demo App
===================
The demo App has been patch to compile and work with the new types.
Developers must consider that the use (and abuse) of forced_try and
forced unwrapping is a "license" that maintainers are using for the
sake of brevity. We consider that clients of this SDK do know how to
handle Errors and Optional and it is not the objective of the demo
code to show good practices on those matters.

[#381] Move Zatoshi and Amount Types to the SDK (#396)
Closes #381

This commit brings a Zatoshi type developed on the Secant project,
helper classes like Clamped and tests.

Zatoshi has been incorporated as a Codable type for SQLite Swift
to allow serialization into the pending database.
