* [core] Introduce FileSourceManager and use it for default platform impl
- Add `FileSourceManager` interface that provides access to `FileSource`
instances and means of registering / unregistering `FileSource` factories
- Split `DefaultFileSource` into smaller parts
- Add `DatabaseFileSource` interface and it's default implementation
- Remove inter-dependencies between concrete `FileSource` classes
* [build] Add files to next build system
* [core] Add generic property setters / getters
* [core] Remove setOnlineStatus from OnlineFileSource interface
* [core] Hide threading implementation details from DatabaseFileSource interface
* [core] Make DB file source methods virtual
* [core] Add documentation for DatabaseFileSource and rename one method
* [core] Use simple callback instead of ActorRef
* [core] Remove ActorRef from OnlineFileSource public header
* [core] Add callback to FileSource::forward async API
* [core] Pass OfflineRegionDefinition by value
* [core] Update tests to use modular file sources
* [core] Update unit tests
* [core] Update unit tests after rebase
* [core] Backport low prio fix for cached requests
* [core] Backport pack database
* [core] Return removed factory from unRegisterFileSourceFactory
* [core] Rename shadowed args in onlinefilesource
* [core] Remove simple std::function callback aliases
* [core] Expose online file source property keys in public header file
* [test-runner] Add proxy file source test runner
* [cache] Update mbgl-cache utility to use new file source
