Summary: Currently, PlainTable must use mmap_reads. When PlainTable is used but allow_mmap_reads is not set, rocksdb will fail in flush. This diff improve Options sanitization and add MmapReadRequired() to TableFactory. Test Plan: export ROCKSDB_TESTS=PlainTableOptionsSanitizeTest make db_test -j32 ./db_test Reviewers: sdong, ljin Reviewed By: ljin Subscribers: you, leveldb Differential Revision: https://reviews.facebook.net/D21939
