Bug#32430: 'show innodb status' causes errors

Invalid (old?) table or database name in logs

Problem was still not completely fixed, due to
qouting.

This is the server side only fix (in explain_filename),
the change from filename_to_tablename to use explain_filename
in the InnoDB code must be done before the bug is
fixed.


mysql-test/include/have_not_innodb_plugin.inc:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  Added include file to allow test for only the
  'old' built-in innodb engine
mysql-test/r/not_true.require:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  Added require to match 'not' TRUE
mysql-test/r/partition_innodb_builtin.result:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  New result file for partitioning specific to
  the 'old' built-in innodb engine
mysql-test/r/partition_innodb_plugin.result:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  New result file for partitioning specific to
  the new plugin innodb engine
mysql-test/t/disabled.def:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  Disabling the new test until the fix is
  included in the InnoDB source too.
mysql-test/t/partition_innodb_builtin.test:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  New test file for partitioning specific to
  the 'old' built-in innodb engine

  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  New test file for partitioning specific to
  the new plugin innodb engine
sql/mysql_priv.h:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  Added thd as a parameter to explain_filename
  to be able to use the correct quote character
sql/sql_table.cc:
  Bug#32430: 'show innodb status' causes errors
  Invalid (old?) table or database name in logs
  
  Changed explain_filename, so that it does qouting
  correctly according to the sessions qoute char.
