Item_func_user doesn't calculate anything in it's val_str() method,
just returns saved str_value.
Though Item::save_in_field method can destroy str_value, relying on
val_str() return. As a result we get the garbage stored in field.
We cannot use Item::save_in_field implementation for Item_func_user,
reimplement it in simpler way.

unpack_fields() didn't expect NULL_LENGHT in the field's descriptions.

The result string of the Item_func_group_concat wasn't initialized in the
copying constructor of the Item_func_group_concat class. This led to a
wrong charset of GROUP_CONCAT result when the select employs a temporary
table.
The copying constructor of the Item_func_group_concat class now correctly
initializes the charset of the result string.

For each view the mysqldump utility creates a temporary table
with the same name and the same columns as the view
in order to satisfy views that depend on this view.
After the creation of all tables, mysqldump drops all
temporary tables and creates actual views.
However, --skip-add-drop-table and --compact flags disable
DROP TABLE statements for those temporary tables. Thus, it was
impossible to create the views because of existence of the
temporary tables with the same names.

The get_time_value function is added. It is used to obtain TIME values both
from items the can return time as an integer and from items that can return
time only as a string.
The Arg_comparator::compare_datetime function now uses pointer to a getter
function to obtain values to compare. Now this function is also used for
comparison of TIME values.
The get_value_func variable is added to the Arg_comparator class.
It points to a getter function for the DATE/DATETIME/TIME comparator.

The Field_newdate::store when storing a DATETIME value was returning the
'value was cut' error even if the thd->count_cuted_fields flag is set to
CHECK_FIELD_IGNORE. This made range optimizr think that there is no
appropriate data in the table and thus to return an empty set.
Now the Field_newdate::store function returns conversion error only if the
thd->count_cuted_fields flag isn't set to CHECK_FIELD_IGNORE.

pseudo_thread_id was reset to zero via mysql_change_user() handling
whereas there is no reason to do that. Moreover, having two
concurrent threads that change user and create a namesake temp tables
leads to recording the dup pair of queries:
set @@session.pseudo_thread_id = 0;
CREATE temporary table `the namesake`;
which will stall the slave as the second instance can not be created.
And that is the bug case.
Fixed by correcting pseudo_thread_id value after mysql_change_user().
sql/sql_class.cc:
Fixed that pseudo_thread_id was set to 0 after mysql_change_user().
gettimeofday() can fail and presumably, so can time().
Keep an eye on it.
Since we have no data on this at all so far, we just
retry on failure (and log the event), assuming that
this is just an intermittant failure. This might of
course hang the threat until we succeed. Once we know
more about these failures, an appropriate more clever
scheme may be picked (only try so many times per thread,
etc., if that fails, return last "good" time() we got or
some such). Using sql_print_information() to log as this
probably only occurs in high load scenarios where the debug-
trace likely is disabled (or might interfere with testing
the effect). No test-case as this is a non-deterministic
issue.
