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`.

Michal Fousek e01c83690f [#646] SDK sync process resumes correctly
- Previously we had one range for each sync which was used for each
  phase of sync process. Newly there is separate range for each phase of
  the sync process.
- I added `InternalSyncProgress` utility. This utility tracks progress
  of some phases. And it is able to compute right ranges which should be
  used for syncing.
- Some unused download code from `CompactBlockProcessor` is removed.

Fix tests

Address review comments

- Rebase to master
- Update how range for `processBatchFinished()` is computed.
- Refactor `InternalSyncProgress`
- Add tests for `InternalSyncProgress`

Address review comments

Change how latest downloaded block is tracked

- Cache DB is no longer used to track which block was downloaded as
  latest. `InternalSyncProgress` is used to do that.
- Thanks to that #660 is fixed. And cache DB can be completely removed
  after sync process.
- Added sleep(1) to some darkside tests when latest block height is set.
  Otherwise lightwalletd in darkside mode doesn't have time to setup and
  tests are flaky.

`XCAsyncTestCase` does not work as intended but `wait {}` does what
we need.
