Fixes for

     Bug#30418 "datadict" tests (all engines) fail: Dependency on the host name
                for ordering
     Bug#30420 "datadict" tests (all engines) fail: Release build has help tables loaded
     Bug#30438 "{memory,myisam,ndb}__datadict" tests fail: Use "InnoDB" without checking
     Bug#30440 "datadict" tests (all engines) fail: Character sets depend on configuration
Attention: Only the build team can check if Bug#30440 is really fixed.

  Update README
mysql-test/suite/funcs_1/datadict/datadict_master.inc:
  1. Exclude the help tables from the INFORMATION_SCHEMA.TABLES
     and the INFORMATION_SCHEMA.STATISTICS selects.
  2. Replace error numbers with error names
  3. Sort some results with mysqltest builtin function
  4. Some other minor changes

+-------------------
+Fixes for Bugs 30418,30420,30438,30440 
+1. Replace error numbers with error names
+2. Replace static "InnoDB" (not all time available) used within an
+   "alter table" by $OTHER_ENGINE_TYPE (set to MEMORY or MyISAM).
+   Minor adjustment of column data type.
+3. Use mysqltest result set sorting in several cases.
+4. Avoid any statistics about help tables, because their content
+   depends on configuration:
+   developer release - help tables are empty
+   build release     - help tables have content + growing with version
+5. Add two help table related tests (one for build, one for developer)
+   to ensure that informations about help tables within
+   INFORMATION_SCHEMA.TABLES/STATISTICS are checked.
+General note:
+   Most INFORMATION_SCHEMA properties (table layout, permissions etc.)
+   are not affected by our variation of the storage engines except
+   that some properties of our tables using a specific storage
+   engine become visible. So it makes sense to decompose
+   this test into a storage engine specific part and a non
+   storage engine specific part in future.
