This patch changes test to remove Windows-specific limitations and potential
rounding errors in the calculation of a UDF.

Also corrects a minor merge conflict.

This patch corrects an error in the header file concerning a method declaration
in the header file. Compiles ok on Windows, but not on Linux. 

  
This patch corrects errors that occurred in a local manual merge.
It adds the originator column in the results of the SHOW EVENTS command
for a series of tests.

The only code change is to correct references to the classname in
enums.

there is a way to miss allocation for the punctuation marks,
namely if (q == EOF) is true inside of append_identifier(), i.e in case names are not quoted
(not by default).

Replacing q_append with the method with reallocation if needed.

rows event):

Adding a after image COLS bitmap to Update_rows_log_event (for telling
what columns that are present in the after image of each row update).

Also fixing case where Rows_log_event length was not correctly computed
(happened when the number of columns in a table was more than 251). 

- Fixing utf8_general_cs according to recent changes.
- Compiling utf8_general_cs in pentium-debug-max configuration
  to avoid these problems in the future.

Fix: adding namespace reference into "mysql --xml" output,
to make it work similary to "mysqldump --xml".

Problem: GROUP BY on empty ucs2 strings crashed server.
Reason: sometimes mi_unique_hash() is executed with
ptr=null and length=0, which means "empty string".
The branch of code handling UCS2 character set
was not safe against ptr=null and fell into and
endless loop even if length=0 because of poiter
arithmetic overflow.
Fix: adding special check for length=0 to avoid pointer arithmetic
overflow.
