                    documentation

While the manual mentions FRAC_SECOND only for the TIMESTAMPADD()
function, it was also possible to use FRAC_SECOND with DATE_ADD(),
DATE_SUB() and +/- INTERVAL.

Fixed the parser to match the manual, i.e. using FRAC_SECOND for 
anything other than TIMESTAMPADD()/TIMESTAMPDIFF() now produces a 
syntax error.

Additionally, the patch allows MICROSECOND to be used in TIMESTAMPADD/
TIMESTAMPDIFF and marks FRAC_SECOND as deprecated.

suppress the "Out of sort memory" error in the error log.

                 for wildcard values.
The server ignored escape character before wildcards during
the calculation of priority values for sorting of a privilege
list. (Actually the server counted an escape character as an
ordinary wildcard like % or _). I.e. the table name template
with a wildcard character like 'tbl_1' had higher priority in
a privilege list than concrete table name without wildcards
like 'tbl\_1', and some privileges of 'tbl\_1' was hidden
by privileges for 'tbl_1'.

The get_sort function has been modified to ignore escaped
wildcards as usual.

                 type conversion.

Instead of copying of whole character string from a temporary
buffer, the server copied a short-living pointer to that string
into a long-living structure. That has been fixed.

                    or trigger crashes server

Under some circumstances a combination of VIEWs, subselects with outer
references and PS/SP/triggers could lead to use of uninitialized memory
and server crash as a result.

Fixed by changing the code in Item_field::fix_fields() so that in cases
when the field is a VIEW reference, we first check whether the field
is also an outer reference, and mark it appropriately before returning.

Field data for a query was stored to the stmt->alloc that is emptied
with mysql_stmt_close statement only. That means a lot of memory can
be occupied without a reason if used doesn't call mysql_stmt_close often.

SET column storing procedure has been modified to be 64bit-clean.

The out of memory error was thrown when the sort buffer size were too small.
This led to a user confusion.

Now filesort throws the error message about sort buffer being too small.

  Minor post-fix for bug#34223.

The bug was that handler::clone/handler::ha_open() call caused allocation of 
cloned_copy->ref on the handler->table->mem_root. The allocated memory could not 
be reclaimed until the table is flushed, so it was possible to exhaust memory by 
repeatedly running index_merge queries without doing table flushes.  

The fix:
- make handler::clone() allocate new_handler->ref on the passed mem_root 
- make handler::ha_open() not allocate this->ref if it has already been allocated
There is no testcase as it is not possible to check small leaks from testsuite.
