This changeset belongs to

      WL#3397 Refactoring storage engine test cases (for falcon)
    It contains also fixes according to code review.
    Contents: Testcases which were in history dedicated to InnoDB or MyISAM only.
    Modifications:
    1. Shift the main testing code into include/<testing field>.inc
       Introduce $variables which can be used to omit tests for features which are not supported by
       certain storage engines.
    2. The storage engine to be tested is assigned within the toplevel script (t/<whatever>_<engine>.test)
       via variable $engine_type and the the main testing code is sourced from 
       include/<testing field>.inc
    3. Some toplevel testscripts have to be renamed to
       - avoid immediate or future namespace clashes
       - show via filename which storage engine is tested
    4. Minor code cleanup like remove trailing spaces, some additional comments ....

mysql-test/include/concurrent.inc:
  1. This file contains now the main testing code of the former t/innodb_concurrent.test.
  2. It is now sourced by t/concurrent_innodb.test.
mysql-test/include/deadlock.inc:
  1. This file contains now the main testing code of the former t/innodb-deadlock.test
  2. It is now sourced by t/deadlock_innodb.test.
mysql-test/include/handler.inc:
  1. This file contains now the main testing code of the former t/innodb_handler.test + t/handler.test.
  2. It is now sourced by t/handler_myisam.test and t/handler_innodb.test.
mysql-test/include/index_merge1.inc:
  1. This file contains now the main testing code of the former t/index_merge.test.
  2. It is now sourced by t/index_merge_myisam.test.
mysql-test/include/index_merge2.inc:
  1. This file contains now the main code of t/index_merge_innodb.test.
  2. It is sourced by t/index_merge_myisam.test and t/index_merge_innodb.test.
mysql-test/include/index_merge_2sweeps.inc:
  1. This file contains now the main code of the former t/index_merge_innodb2.test.
  2. It is sourced by t/index_merge_myisam.test and t/index_merge_innodb.test.
mysql-test/include/index_merge_ror.inc:
  1. This file contains now the main code of the former t/index_merge_ror.test.
  2. It is sourced by t/index_merge_myisam.test.
mysql-test/include/index_merge_ror_cpk.inc:
  1. This file contains now the main testing code of the former t/index_merge_ror_cpk.test.
  2. It is now sourced by t/index_merge_myisam.test and t/index_merge_innodb.test.
mysql-test/include/mix1.inc:
  1. This file contains now the main testing code of the t/innodb_mysql.test
  2. The name mix1.inc was used because the test contains subtests for different fields.
  3. It is sourced by t/innodb_mysql.test.
  4. Fixes:
      - Assign $other_engine_type instead of hardcoded MyISAM.
      - improve comment
      - remove redundant subtest
      - analyze table t4 instead of wrong table t1
      - remove not needed "eval set storage_engine = $engine_type;"
mysql-test/include/mix2.inc:
  1. This file is a copy of the main testing code of the t/innodb.test
     A copy has to be used, because t/innodb.test is to be maintained by INNOBASE only.
  2. The name mix2.inc was used because the test contains subtests for different fields.
  3. It is sourced by t/mix2_myisam.test.
  4. Fixes:
      - improved comment
      - additional "eval SET SESSION STORAGE_ENGINE = $other_engine_type;" at beginning of tests
      - assign $other_engine_type instead of hardcoded MyISAM or HEAP
      - assign $other_engine_type where it is needed to preserve test logics
      - correct logical bugs
      - improve(extend) "checksum table" test
