* RocksDB may print large log lines up to 64k. The default 1k buffer for `logv` is too small and truncates rocksdb log. When we detect log line is too long, we allocate a large enough buffer on heap and try again.
* When log level is not specified, defaults to header level.

* use shared_ptr for rate limiter
