Summary: Adapted a stderr logger from the option tests. Moved it to a separate header so we can reuse it, e.g., from ldb subcommands for faster debugging. This is especially useful to make errors/warnings more visible when running "ldb repair", which involves potential data loss. Test Plan: ran options_test and "ldb repair" $ ./ldb repair --db=./tmp/ [WARN] **** Repaired rocksdb ./tmp/; recovered 1 files; 588bytes. Some data may have been lost. **** OK Reviewers: IslamAbdelRahman, yhchiang, sdong Reviewed By: sdong Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D56151
