Summary: This patch is to address @haobo's comments on D13521: 1. rename Table to be TableReader and make its factory function to be GetTableReader 2. move the compression type selection logic out of TableBuilder but to compaction logic 3. more accurate comments 4. Move stat name constants into BlockBasedTable implementation. 5. remove some uncleaned codes in simple_table_db_test Test Plan: pass test suites.
