is inconsistent
+ several improvements
Details:
- The subtest with assignment of floating point numbers to
  DECIMAL parameters in functions and procedures checks
  now that the final DECIMAL value is the same as if we assign
  the floating point numbers to columns, user variables etc.
  = The impact of math libs or truncation must be the same.
- Remove storage engine variants of this test because the
  stored procedure properties tested do not depend on
  the storage engine.
  Use the fastest storage engine (MEMORY) for any tables
  needed.
- reset global sort_buffer_size to startup value
- Partially improved formatting.

Bug#37114: sql_mode NO_BACKSLASH_ESCAPES does not work properly with LOAD DATA      Bug#37114: sql_mode NO_BACKSLASH_ESCAPES does not work properly with LOAD DATA INFILE

tweaked test to make embedded server happy

NO_BACKSLASH_ESCAPES was not heeded in LOAD DATA INFILE
and SELECT INTO OUTFILE.  It is now.

mysql-test/r/loaddata.result:
  Show that SQL-mode NO_BACKSLASH_ESCAPES is heeded in
  INFILE/OUTFILE, and that dump/restore cycles work!
mysql-test/t/loaddata.test:
  Show that SQL-mode NO_BACKSLASH_ESCAPES is heeded in
  INFILE/OUTFILE, and that dump/restore cycles work!
sql/sql_class.cc:
  Add function to enquire whether ESCAPED BY was given.
  When doing SELECT...OUTFILE, use ESCAPED BY if specifically
  given; otherwise use sensible default value depending on
  SQL-mode features NO_BACKSLASH_ESCAPES.
sql/sql_class.h:
  Add function to enquire whether ESCAPED BY was given.
sql/sql_load.cc:
  When doing LOAD DATA INFILE, use ESCAPED BY if specifically
  given; otherwise use sensible default value depending on
  SQL-mode features NO_BACKSLASH_ESCAPES.

Details:
- backport of some improvements which prevent sporadic
  failures from 5.1 to 5.0
- @@GLOBAL.CONCURRENT_INSERT= 0 also for slave server
- --sorted_result before all selects which have result
  sets with more than one row
- Replace error numbers by error names

                  
Fix the write_record function to record auto increment
values in a consistent way.

mysql-test/r/auto_increment.result:
  Updated the test result file with the output of the
  new test case added to verify this bug.
mysql-test/t/auto_increment.test:
  Added a new test case to verify this bug.
sql/sql_insert.cc:
  The algorithm for the write_record function
  in sql_insert.cc is (more emphasis given to
  the parts that deal with the autogenerated values)
  
  1) If a write fails
  
     1.1) save the autogenerated value to avoid 
          thd->insert_id_for_cur_row to become 0.
  
     1.2) <logic to handle INSERT ON DUPLICATE KEY
          UPDATE and REPLACE>
  
  2) record the first successful insert id.
  
  explanation of the failure
  --------------------------
  
  As long as 1.1) was executed 2) worked fine.
  
  1.1) was always executed when REPLACE worked 
       with the last row update optimization, but
       in cases where 1.1) was not executed 2)
       would fail and would result in the autogenerated
       value not being saved.
  
  solution
  --------
  
  repeat a check for thd->insert_id_for_cur_row 
  being zero similar to 1.1) before 2) and ensure
  that the correct value is saved.

Correct usage of strncat() in get_symbol_path()

3rd parameter to strncat is changed to be count of 
remaining bytes in the output buffer minus 1.

Merge of fixes from 5.0 -> 5.1
Moved restoration of concurrent_insert's original value to the end of the 5.1 tests
Re-recorded .result file to account for changes to test file.

Moved fix for this bug to 5.0 as other mysqldump bugs seem tied to concurrent_insert being on
Setting concurrent_insert off during this test as INSERTs weren't being 
completely processed before the calls to mysqldump, resulting in failing tests.

Altered .test file to turn concurrent_insert off during the test and to restore it
to whatever the value was at the start of the test when complete.

Re-recorded .result file to account for changes to variables in the test.

Fixed bad path in .test file
Moved test to suite/rpl_ndb (per Cluster QA)
Re-recorded .result file to updated expected results.

The problem here is that symbols can not be loaded, because symbol
path is not set and  default path does not include the directory
where PDB is located.

The problem is _not_ reproducible on the same machine where
mysqld.exe is built - if PDB is not found in the symbol path,
dbghelp would fallback to fully qualified PDB path as given in the
executable header and on the build host this will succeed.

The solution is to calculate symbol path and pass it to SymInitialize()
call.

Problem: with @@sql_mode=pad_char_to_full_length
a CHAR column returned additional garbage
after trailing space characters due to
incorrect my_charpos() call.
Fix: call my_charpos() with correct arguments.

  bug #31231  mysql_alter_table() tries to drop a non-existing table
  Don't invoke handler for tables defined with FRM_ONLY flag.
  bug#31233 mysql_alter_table() fails to drop UNIQUE KEY
  When a table is defined without an explicit primary key
  mysql will choose the first found unique index defined over
  non-nullable fields (if such an index exists). This means
  that if such an index is added (the first) or dropped (the last)
  through an alter table, this equals adding or dropping a primary key.
  The implementation for on-line add/drop index did not consider
  this semantics. This patch ensures that only handlers with the
   correctly defined flags (see handler.h for explanation of the flags):
  HA_ONLINE_ADD_PK_INDEX
  HA_ONLINE_ADD_PK_INDEX_NO_WRITES
  HA_ONLINE_DROP_PK_INDEX
  HA_ONLINE_DROP_PK_INDEX_NO_WRITES
  are invoked for such on-line operations. All others handlers must
  perform a full (offline) alter table.

      
If a delayed insert thread was aborted by a concurrent 'truncate table'
statement, then the diagnostic area would fail with an assert in a debug build
because no actual error message was pushed on the stack despite a thread
being killed.
      
This patch adds an error message to the stack.


sql/sql_insert.cc:
  * Changed sql_print_error() to my_error() to avoid assertion in the DA
  * Added assertion in "should never happen" branch.
