Backport mysql-test/t/myisam_explain_non_select_all.test from mysql-5.6 - the .result file was modified because MariaDB choses different query plans in a number cases. Also, we don't have some of the "incorrect EXPLAIN output" bugs that they still have. The .test file and includes were taken verbatim with one exception: two tests were disabled with --disable parsing: 1. @@sql_safe_updates is not enforced EXPLAINs of multitable updates. In MariaDB, the execution itself will produce ER_UPDATE_WITHOUT_KEY_IN_SAFE_MODE, but EXPLAIN won't. 2. Their case #71 hits some old bug in MyISAM (See their comments in explain_non_select.inc for details).
