overlay support for mysql-test-run and mysqltest

mysql-test-run auto-disables all optional plugins.


mysql-test/include/default_client.cnf:
  no @OPT.plugindir anymore
mysql-test/include/default_mysqld.cnf:
  don't disable plugins manually - mtr can do it better
mysql-test/suite/innodb/t/innodb_bug47167.test:
  mtr now uses suite-dir as an include path
mysql-test/suite/innodb/t/innodb_file_format.test:
  mtr now uses suite-dir as an include path
mysql-test/t/partition_binlog.test:
  this test uses partitions
storage/example/mysql-test/mtr/t/source.result:
  update results. as mysqltest includes the correct overlayed include
storage/innobase/handler/ha_innodb.cc:
  the assert is wrong

+# This tests the following:

+#   it includes combs.inc (indirectly, via proxy.inc) with two more combinations
+#   thus it should run 4 times
+#
+#   combs.combinations is overlayed in the example overlay, adding one more
+#   combination. Thus simple.test must run two more times in the mtr-example.
+#
+#   Note that neither simple.test nor proxy.inc are touched by the overlay,
+#   mtr needs to propagate "affected by the overlay" flag up the
