This assert could be triggered if -1 was inserted into
an auto increment column by a statement writing more than
one row.

Unless explicitly given, an interval of auto increment values
is generated when a statement first needs an auto increment
value. The triggered assert checks that the auto increment
counter is equal to or higher than the lower bound of this
interval.

Generally, the auto increment counter starts at 1 and is
incremented by 1 each time it is used. However, inserting an
explicit value into the auto increment column, sets the auto
increment counter to this value + 1 if this value is higher
than the current value of the auto increment counter.

This bug was triggered if the explicit value was -1. Since the
value was converted to unsigned before any comparisons were made,
it was found to be higher than the current vale of the auto
increment counter and the counter was set to -1 + 1. This value
was below the reserved interval and caused the assert to be
triggered the next time the statement tried to write a row.

With the patch for Bug#39828, this bug is no longer repeatable.
Now, -1 + 1 is detected as an "overflow" which causes the auto
increment counter to be set to ULONGLONG_MAX. This avoids hitting
the assert for the next insert and causes a new interval of
auto increment values to be generated. This resolves the issue.

This patch therefore only contains a regression test and no code
changes. Test case added to auto_increment.test.

Fixed the test case to be independent of build options used.
Removed the lowercase-table-names constraint, since performance schema tables are now in lowercase.

so will be run only weekly; this closes BUG#50595.

      
mysqlbinlog only prints "use $database" statements to its output stream
when the active default database changes between events. This will cause
"No Database Selected" error when dropping and recreating that database.
      
To fix the problem, we clear print_event_info->db when printing an event
of CREATE/DROP/ALTER database statements, so that the Query_log_event
after such statements will be printed with the use 'db' anyway except
transaction keywords.


mysql-test/r/mysqlbinlog.result:
  Test result for Bug#50914.
mysql-test/t/mysqlbinlog.test:
  Added test to verify if the approach of the mysqlbinlog prints
  "use $database" statements to its output stream will cause
  "No Database Selected" error when dropping and recreating
  that database.
sql/log_event.cc:
  Updated code to clear print_event_info->db when printing an event
  of CREATE/DROP/ALTER database statements, so that the Query_log_event
  after such statements will be printed with the use 'db' anyway except
  transaction keywords.

- Changed a few GPL texts to use "program" instead of "library"

ASSERT happens due to improper calculation of the max_length
in Item_func_div object, if dividend has max_length == 0 then
Item_func_div::max_length is set to 0 under some circumstances.
The fix:
If decimals == NOT_FIXED_DEC then set
Item_func_div::max_length to max possible
DOUBLE length value.

BUG #59055: RQG was broken after the checkin that removed rpl and rpl_ndb suites. RQG uses MTR V1 and that still has these in the default suite. Removing these from V1. Also removing references to ndb tests in some more disabled.def files

Problem: master executed a statement that would fail on slave
(namely, DROP USER 'create_rout_db'@'localhost').
Then the test did:
  --let $rpl_only_running_threads= 1
  --source include/rpl_reset.inc
rpl_reset.inc calls rpl_sync.inc, which first checks which of
the threads are running and then syncs those threads that are
running. If the SQL thread fails after the check, the sync will
fail. So there was a race in the test and it failed on some
slow hosts.
Fix: Don't replicate the failing statement.

Item_sum_max/Item_sum_min incorrectly set null_value flag and
attempt to get result in parent functions leads to crash.
This happens due to double evaluation of the function argumet.
First evaluation happens in the comparator and second one
happens in Item_cache::cache_value().
The fix is to introduce new Item_cache object which
holds result of the argument and use this cached value
as an argument of the comparator.
