ASTERIXDB-1045: Log analysis fixes

-Avoid using exceptions for control flow in LogRecord
-Rename LogPage and ilk to LogBuffer
-Busywait on read() to fill entire buffer for fillLogBuffer rather than failing
-Distinguish between log truncation and checksum corruption

TODOs:
- Log IO and parsing still happen in lock-step.
- Busywaiting for read to return something other than 0 is unfortunate
