Yanqin Jin dd203ed604 Disallow a combination of options (#9348) ... Summary: Disallow `immutable_db_opts.use_direct_io_for_flush_and_compaction == true` and `mutable_db_opts.writable_file_max_buffer_size == 0`, since it causes `WritableFileWriter::Append()` to loop forever and does not make much sense in direct IO. This combination of options itself does not make much sense: asking RocksDB to do direct IO but not allowing RocksDB to allocate a buffer. We should detect this false combination and warn user early, no matter whether the application is running on a platform that supports direct IO or not. In the case of platform **not** supporting direct IO, it's ok if the user learns about this and then finds that direct IO is not supported. One tricky thing: the constructor of `WritableFileWriter` is being used in our unit tests, and it's impossible to return status code from constructor. Since we do not throw, I put an assertion for now. Fortunately, the constructor is not exposed to external applications.
