SQL-mode PAD_CHAR_TO_FULL_LENGTH affected mysqld's user-table too. If
enabled, user-name and host were space-padded and no longer matched
the login-data of incoming connexions.

Patch disregards pad-flag while loading privileges so ability to log
in does not depend on SQL-mode.

Under some circumstances a combination of aggregate functions and
GROUP BY in a SELECT query over a VIEW could lead to incorrect
calculation of the result type of the aggregate function. This in
turn could result in incorrect results, or assertion failures on debug
builds.

Fixed by changing the logic in Item_sum_hybrid::fix_fields() so that
the argument's item is dereferenced before calling its type() method.

                 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)
  like % and _ wildcards in the get_sort function for sorting weights
  calculation.
  
  The get_sort function has been modified to ignore escaped wildcards
  and alone escapes like in the wild_case_compare function.

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.

  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 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.
