This patch implements testing InnoDB plugin milestone.

mysql-test/lib/mtr_cases.pm:
  Expand test cases list with test cases to test
  InnoDB plugin.
mysql-test/mysql-test-run.pl:
  Added "innodb" suite to default list of suites.
mysql-test/suite/innodb/include/have_innodb_plugin.inc:
  This file determines if innodb plugin is available.
mysql-test/suite/innodb/my.cnf:
  Removed temporary my.cnf, which was added for testing. Not
  needed anymore - options are substituted by mtr.
mysql-test/suite/innodb/t/innodb-analyze.test:
  This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb-timeout.test:
  This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb-use-sys-malloc-master.opt:
  Use "loose" prefix with mysqld options. This makes this
  test skipped properly when no innodb is available.
mysql-test/suite/innodb/t/innodb-use-sys-malloc.test:
  This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb-zip.test:
  This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb_bug36169.test:
  This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb_bug36172.test:
  This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb_information_schema.test:
  This test can only be run with InnoDB plugin.
