ASTERIXDB-1425 & ASTERIXDB-1450: Fix LogReader random reads

- Fix random reads for truncated logs (ASTERIXDB-1425).
- Fix log file partition size boundary check (ASTERIXDB-1450).
- Fix deadlock between LogReader and LogFlusher.
- Prevent checkpoints from deleting log files being accessed by rollbacks.
- Make rollbacks start from LSN = max(txnFirstLSN, minMemoryLSN).
- Make default log partition size 250MB instead of 2GB.
