Optimization of persistent state serialization (#364)

Browse source 
* Fix double serialization of masterchain; increase sync_blocks_before

* Improve logging in DownloadState

* Write persistent state directly to file instead of a buffer

* Don't keep ref to masterchain state in AsyncStateSerializer

* Sparse state serialization over longer period
