Bug #30316: Some "parts" tests fail because the server uses "--secure-file-priv"
Bug #30341: Test suite "parts" needs to be adapted to the new rules disallowing many functio
Bug #30408: Suite "parts" needs bug numbers updated
Bug #30411: Suite "parts" needs bug numbers updated: ER_UNIQUE_KEY_NEED_ALL_FIELDS_IN_PF
Bug #30576: part_supported_sql_func_innodb.test tries to LOAD DATA outside of var dir
Bug #30581: partition_value tests use disallowed CAST() function

Included are some general fixes to allow the "parts" test suite to be run
successfully.  This includes disabling a few tests or parts of tests,
cleaning up the test cases and their results, etc.  Basically, these tests
have not been run for some time, and had suffered some bit rot.

The bugs were fixed as a single changeset, because in some ways they depend
on each other.  I couldn't be sure I'd updated all the error codes (for
bugs 30408 and 30411) without also adapting to the new allowed functions
rules (bug 30341), and vice versa.


mysql-test/include/partition_layout.inc:
  Ensure that the contents of $MYSQLTEST_VARDIR are not in the result file
mysql-test/suite/parts/inc/part_blocked_sql_funcs_main.inc:
  Add ASCII(), ORD() and WEEKOFYEAR() as blocked functions (they depend
  too much on character set, etc.).
  
  Remove DATEDIFF() as a blocked function (it is implemented in terms
  of TO_DAYS() and the minus operator).
mysql-test/suite/parts/inc/part_supported_sql_funcs_main.inc:
  Remove ASCII(), ORD() and WEEKOFYEAR(), which are not allowed functions.
  
  Remove uses of CAST() in partitioning functions - it is not allowed.
  
  Disable testing of FLOOR() and CEILING on non-integer fields, due to
  Bug 30577.
  
  Test MOD() with an integer field instead of floating point (it has a
  hybrid result type, like FLOOR() and CEILING(), but makes sense to use
  with an integer field).
  
  Add DATEDIFF() as an allowed function, because it is implemented in
  terms of TO_DAYS() and the minus operator.
mysql-test/suite/parts/inc/partition_alter3.inc:
  Remove use of disallowed CAST() function in partitioning
mysql-test/suite/parts/inc/partition_blocked_sql_funcs.inc:
  The blocked functions are actually blocked now, so expect errors.
  
  This is a result of the fix for bug 18198.
mysql-test/suite/parts/inc/partition_date.inc:
  Remove uses of CAST() in partitioning functions - it is not allowed.
mysql-test/suite/parts/inc/partition_datetime.inc:
  Remove uses of CAST() in partitioning functions - it is not allowed.
mysql-test/suite/parts/inc/partition_decimal.inc:
  Remove uses of CAST() in partitioning functions - it is not allowed.
  
  Disable testing of FLOOR() and CEILING(), due to Bug 30577.
mysql-test/suite/parts/inc/partition_directory.inc:
  Ensure that the contents of $MYSQLTEST_VARDIR are not in the result file
mysql-test/suite/parts/inc/partition_double.inc:
  Remove uses of CAST() in partitioning functions - it is not allowed.
  
  Disable testing of FLOOR() and CEILING(), due to Bug 30577.
mysql-test/suite/parts/inc/partition_enum.inc:
  Remove use of CAST(), which is disallowed.
  
  Remove test which relies on CAST().
mysql-test/suite/parts/inc/partition_float.inc:
  Remove uses of CAST() in partitioning functions - it is not allowed.
  
  Disable testing of FLOOR() and CEILING(), due to Bug 30577.
mysql-test/suite/parts/inc/partition_layout_check1.inc:
  Ensure that the contents of $MYSQLTEST_VARDIR are not in the result file
mysql-test/suite/parts/inc/partition_layout_check2.inc:
  Ensure that the contents of $MYSQLTEST_VARDIR are not in the result file
mysql-test/suite/parts/inc/partition_methods1.inc:
  Ensure that the contents of $MYSQLTEST_VARDIR are not in the result file
mysql-test/suite/parts/inc/partition_set.inc:
  Remove test which relies on CAST(), which is disallowed.
mysql-test/suite/parts/inc/partition_supported_sql_funcs.inc:
  Fix Bug #30576: part_supported_sql_func_innodb.test tries to LOAD DATA outside of var dir
  
  Move data files into std_data/parts/*, so they can be used with LOAD
  DATA INFILE '../std_data_ln/parts/*' while --secure-file-priv is in
  force.
mysql-test/suite/parts/inc/partition_syntax.inc:
  Remove use of CAST(), which is disallowed.
mysql-test/suite/parts/inc/partition_time.inc:
  Remove use of CAST(), which is disallowed.
mysql-test/suite/parts/inc/partition_timestamp.inc:
  Remove use of CAST(), which is disallowed.
mysql-test/suite/parts/inc/partition_value.inc:
  Disable this entire test file, because it relies on using CAST() as
  a partitioning function, which is disallowed.  See Bug 30581,
  "partition_value tests use disallowed CAST() function".
