MDEV-5834: Merge Kakao Defragmentation implementation to MariaDB 10.1

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).
