Maysam Yabandeh	235ab9dd32	Pin mmap files in ReadOnlyDB (#4053) ... Summary: https://github.com/facebook/rocksdb/pull/3881 fixed a bug where PinnableSlice pin mmap files which could be deleted with background compaction. This is however a non-issue for ReadOnlyDB when there is no compaction running and max_open_files is -1. This patch reenables the pinning feature for that case.

Yi Wu	7393ef779c	Fix BlockFetcher ASAN error ... Summary: Some call sites of BlockFetcher create temporary ReadOptions and pass to BlockFetcher. The temporary object will be gone after BlockFetcher construction but BlockFetcher keep its reference, causing stack-use-after-scope. Fixing it.

Siying Dong	2f1a3a4d74	Refactor ReadBlockContents() ... Summary: Divide ReadBlockContents() to multiple sub-functions. Maintaining the input and intermediate data in a new class BlockFetcher. I hope in general it makes the code easier to maintain. Another motivation to do it is to clearly divide the logic before file reading and after file reading. The refactor will help us evaluate how can we make I/O async in the future.
