support ha_innodb.so as a dynamic plugin. * remove obsolete *,innodb_plugin.rdiff files * s/--plugin-load=/--plugin-load-add=/ * MYSQL_PLUGIN_IMPORT glob_hostname[] * use my_error instead of push_warning_printf(ER_DEFAULT) * don't use tdc_size and tc_size in a module update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10) * copy new tests over * disable some tests for (old) InnoDB * delete XtraDB tests that no longer apply small compatibility changes: * s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/ * revert unnecessary InnoDB changes to make it a bit closer to the upstream fix XtraDB to compile on Windows (both as a static and a dynamic plugin) disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5) storage/innobase/handler/ha_innodb.cc: revert few unnecessary changes to make it a bit closer to the original InnoDB storage/innobase/include/univ.i: correct the version to match what it was merged from
