The test case for the bug#31048 checks that there is no crash on stack
overrun. But due to different stack sizes on different platforms it failed
on some of them.

The new test case check that a query with at least 4 level subquery nesting
works without the stack overrun nesting and other levels of nesting doesn't
cause a crash.

Zero fill is a field attribute only. So we can't always 
propagate  constants for zerofill fields : the values and 
expression results don't have that flag.

Fixed by converting the const value to a string and 
using that in const propagation when the context allows it. 
Disable const propagation for fields with ZEROFILL flag in
all the other cases.

                 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.

  The server used the wild_prefix escape character (usually \-character)

  and alone escapes like in the wild_case_compare function.

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

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.

  Fixed bug#15409.
  The Field_set::store(longlong nr,...) method incompletely
  calculates a bit mask for the comparison with a given number:
  if that number is greater than 0x7F00 0000 0000 0000 (LONGLONG_MAX),
  it uses zero bit mask instead of 0xFFFF FFFF FFFF FFFF (ULONGLONG_MAX).
  
  Incomplete expression has been replaced with a set_bits macro call.

The unsignedness of large integer user variables was not being
properly preserved when feeded to prepared statements. This was
happening because the unsigned flags wasn't being updated when
converting the user variable is converted to a parameter.

The solution is to copy the unsigned flag when converting the
user variable to a parameter and take the unsigned flag into
account when converting the integer to a string.

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.

Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
   non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
   any mode.

Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.

Binary-encoded string/BLOB columns are not affected.

  Fix: Replace '\\' by '/' in filenames.

    to leave

The artifact was caused by
a flaw in concurrent accessing the slave's io thd by
the io itself and a handling show slave status thread.
Namely, show_master_info did not acquire mi->run_lock mutex that is
specified for mi->io_thd member.

Fixed with deploying the mutex locking and unlocking. The mutex is kept
short time and without interleaving with mi->data_lock mutex.

Todo: to report and fix an issue with 
    sys_var_slave_skip_counter::{methods} 
seem to acquire incorrectly
     active_mi->rli.run_lock
instead of the specified
     active_mi->rli.data_lock

A test case is difficult to compose, so rpl_packet should continue serving
as the indicator.

  mending access to mi->io_thd with the specified mutex;
