Igor Canadi 58ca641d53 Make Log::Reader more robust ... Summary: This diff does two things: (1) Log::Reader does not report a corruption when the last record in a log or manifest file is truncated (meaning that log writer died in the middle of the write). Inherited the code from LevelDB: https://code.google.com/p/leveldb/source/detail?r=269fc6ca9416129248db5ca57050cd5d39d177c8# (2) Turn off mmap writes for all writes to log and manifest files (2) is necessary because if we use mmap writes, the last record is not truncated, but is actually filled with zeros, making checksum fail. It is hard to recover from checksum failing. Test Plan: Added unit tests from LevelDB Actually recovered a "corrupted" MANIFEST file.
