Race condition may occur: mtr sees the .expect file but it's empty
Fix: wait and try again if file is empty
Addendum: try again if line isn't 'wait' or 'restart'
Also added verbose printout of extra restart options

When dates are represented internally as strings, i.e. when a string constant
is compared to a date value, both values are converted to long integers,
ostensibly for fast comparisons. DATE typed integer values are converted to
DATETIME by multiplying by 1,000,000 (each digit pair representing hour,
minute and second, respectively). But the mechanism did not distuinguish
cached INTEGER values, already in correct format, from newly converted
strings.

Fixed by marking the INTEGER cache as being of DATETIME format.

            
rpl_packet got a timeout failure sporadically on PB when stopping
slave. The real reason of this bug is that STOP SLAVE stopped
IO thread first and then stopped SQL thread. It was
possible that IO thread stopped after replicating part of a
transaction which SQL thread was executing. SQL thread would
be hung if the transaction could not be rolled back safely.
            
After this patch, STOP SLAVE will stop SQL thread first and then stop IO
thread, which guarantees that IO thread will fetch the reset of the
events of the transaction that SQL thread is executing, so that SQL
thread can finish the transaction if it cannot be rolled back safely.
            
Added below auxiliary files to make the test code neater.

Fix for bug#45740 introduced test case using SHOW TABLE STATUS against a Memory table using latin1 character in table name.
The test failed on Windows and FreeBSD due to a difference in the value for Avg_row_length.
The average row length normally depends on the values for data length and row count. According to the 5.5 manual data length is approximate with Memory tables.
With MyISAM and InnoDB the Avg_row_length is the same on Windows and Solaris.
The solution implemented by this patch is to mask out the value for Avg_row_length, as it may vary when using Memory tables.

Undoing the patch, it complicates the code but is not the solution

I do not beleive newline mismatch could be the cause of this failure
First, I cannot see how this could be a problem, mtr ignores the newline
  when reading the expect file, and the file is written and read on Windows.
Second, if this really was the problem it should have been deterministic:
  either the newline is correctly interepreted or it is not.

Problem: the scanner function tested for strings "<![CDATA[" and
"-->" without checking input string boundaries, which led to valgrind's
"Conditional jump or move depends on uninitialised value(s)" error.

Fix: Adding boundary checking.

  @ mysql-test/r/xml.result
  @ mysql-test/t/xml.test
  Adding test

  @ strings/xml.c
  Adding a helper function my_xml_parser_prefix_cmp(),
  with input string boundary check.

sys_vars.innodb_max_dirty_pages_pct_func fails sporadically
      

BUG#58858 : sys_vars.innodb_max_dirty_pages_pct_func fails sporadically

Committing After latest merge.      
Modified check_pct procedure to check return value of wait condition instead 
of calling "dirty_pct".
   
Adding Review comments:
1) Added comment for success variable value
2) Procedure check_pct changed For Adding BOOLEAN input and SELECT QUERY Change
