Merge https://github.com/kakao/mariadb-10.0 that contains Facebook's implementation for defragmentation facebook/mysql-5.6@a2d3a74 facebook/mysql-5.6@def96c8 facebook/mysql-5.6@9c67c5d facebook/mysql-5.6@921a81b facebook/mysql-5.6@aa519bd facebook/mysql-5.6@fea7d13 facebook/mysql-5.6@09b29d3 facebook/mysql-5.6@9284abb facebook/mysql-5.6@dbd623d facebook/mysql-5.6@aed55dc facebook/mysql-5.6@aad5c82 This version does not add new SQL-syntax and new handler API function. Instead optimize table is mapped to defragment table if innodb_defragment=ON, by default the feature is off. Contains changes authored by Sunguck Lee (Kakao).
