Even though it returns NULL, the MAKETIME function did not have this property set,
causing a failed assertion (designed to catch exactly this).
Fixed by setting the nullability property of MAKETIME().

Completion of previous patch. Negative number were denied
as the second argument to NAME_CONST.

Locked rows of the InnoDB storage was silently skipped in the read-committed
isolation level.

QUICK_RANGE_SELECT for unique ranges lacks second (blocking) read
of the record that was read semi-consistently and just skip it.

The handler::read_multi_range_next method has been modified
to retry previous unique range if the previous read was
semi-consistent.

A rule was introduced by the 5.1 part of the fix for bug 27531 to 
prefer filesort over indexed ORDER BY when accessing all of the rows of a 
table (because it's faster). This new rule was not accounting for the 
presence of a LIMIT clause.
Fixed the condition for this rule so it will prefer filesort over 
indexed ORDER BY only if no LIMIT.

As the result of DOUBLE claculations can be bigger
than DBL_MAX constant we use in code, we shouldn't use this constatn
as a biggest possible value.
Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
that any rtree_area_increase result will be less so we return valid
key. Though in rtree_area_increase function we calculate the area
of the rectangle, so the result can be 'inf' if the rectangle is
huge enough, which is bigger than DBL_MAX.

Code of the rtree_pick_key modified so we always return a valid key.
