Problem: GROUP BY on empty ucs2 strings crashed server.
Reason: sometimes mi_unique_hash() is executed with
ptr=null and length=0, which means "empty string".
The branch of code handling UCS2 character set
was not safe against ptr=null and fell into and
endless loop even if length=0 because of poiter
arithmetic overflow.
Fix: adding special check for length=0 to avoid pointer arithmetic
overflow.

to 0 causes wrong (large) length to be read
from the row in _mi_calc_blob_length() when
storing NULL values in (e.g) POINT columns.
This large length is then used to allocate
a block of memory that (on some OSes) causes
trouble.
Fixed by calling the base class's
Field_blob::reset() from Field_geom::reset()
that is called when storing a NULL value into
the column.

from func_group.test after the patch for bug #27229 had been applied.
The memory corruption happened because in some rare cases the function
count_field_types underestimated the number of elements in
in the array param->items_to_copy.
sql/item_sum.cc:
The return value of the Item_sum::update_used_tables method
should not depend on the place of aggregation of the set
function for which the Item_sum object has been created.
sql/sql_select.cc:
This is a fix for the memory corruption occurred in one of test cases
from func_group.test after the patch for bug #27229 had been applied.
The memory corruption happened because in some rare cases the function
count_field_types underestimated the number of elements in
in the array param->items_to_copy.
Currently it's not guaranteed that after JOIN::prepare() the
used_tables attribute is calculated for all items. For example
for the expression SUM(outer_ref)+1 used_tables() must return
OUTER_REF_TABLE_BIT. Yet by the moment when the used_tables
attribute is calculated in JOIN::prepare SUM(outer_ref) has
not been substituted for Item_aggregate_ref yet.
By this reason additional calls of the method update_used_tables
are needed for some items passed as parameters to the function
create_tmp_table.
Fix is to rewrite the MBR::overlaps() function, to compute the dimension of both
arguments, and the dimension of the intersection; test that all three dimensions are the
same (e.g., all are Polygons).
Add tests for all MBR* functions for various combinations of shapes, lines and points.
mysql-test/include/gis_generic.inc:
Add tests & checks for bug #24563 and bug #24588 - some GIS functions missing in
5.1; many GIS functions not tested; Overlaps() function was incorrect when MBR shifted
only along one axis; Overlaps() needs to take dimension of shape into account.

sql/spatial.h:
Add MBR::dimension() (map MBR to integral dimension: point -> 0, line -> 1,
polygon -> 2, invalid -> -1)
Fix MBR::overlaps() to handle MBRs which are shifted on one dimension only, and to
take MBR dimension into account. Also, test both within() and contains() predicates (so
that overlaps(a, b) == overlaps(b, a)).

- Improve error handling for "out of memory" problems when master is
sending logs to slave. If memory allocation fails the log should
now report error "memory allocation failed reading log event"
sql/log_event.cc:
Return LOG_READ_MEM from "Log_event::read_log_event" if memory
allocation fails.
