  1. Do readahead in VerifyChecksum() 

    Summary:
Right now VerifyChecksum() doesn't do read-ahead. In some use cases, users won't be able to achieve good performance. With this change, by default, RocksDB will do a default readahead, and users will be able to overwrite the readahead size by passing in a ReadOptions.

Test Plan: Add a new unit test.

Fix db_test build issue in GCC.

Fix the bug.
