Hans Wennborg 213a68eb68 Sync with upstream @23860137 . Fix GCC -Wshadow warnings in LevelDB's public header files, reported by Dustin. Add in-memory Env implementation (helpers/memenv/). This enables users to create LevelDB databases in-memory. Initialize ShardedLRUCache::last_id_ to zero. This fixes a Valgrind warning. (Also delete port/sha1_ which were removed upstream some time ago.)		vor 14 Jahren
