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.

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.

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#31233 mysql_alter_table() fails to drop UNIQUE KEY

      
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.
