Problem was that we considered the point itself as the 'border' object. Instead
of that the 'border' of a POINT is an empty set, and the point is the 'interior'.
Another error fixed by the way - not all operations of the resulting function were properly
allocated.
- Renaming Item::is_bool_func() to is_bool_type(), to avoid assumption
that the item is an Item_func derivant.
- Deriving Item_func_spatial_rel from Item_bool_func rather than Item_int_func
When the distance in ST_BUFFER is too far negative the coordinates can run out of the operational
area. We should just return an empty geometry in this case.
The GEOMETRY field metadata is stored in the FRM file.
SRID for a spatial column now can be stored, it was added to the CREATE TABLE syntax,
so the AddGeometryData() stored procedure is now possible. Script adding the required Add/DropGeometryColumn sp-s added.
Additional fixes for possible overflows in length-related
calculations in 'spatial' implementations.
Checks added to the ::get_data_size() methods.
max_n_points decreased to occupy less 2G size. An
object of that size is practically inoperable anyway.
The bug was found by Alyssa Milburn.
If the number of points of a geometry feature read from
binary representation is greater than 0x10000000, then
the (uint32) (num_points * 16) will cut the higher byte,
which leads to various errors.
Fixed by additional check if (num_points > max_n_points).

Autointersections of an object were treated as nodes, so the wrong result.

A defect in the subquery substitution code may lead to a server crash:
setting substitution's name should be followed by setting its length
(to keep them in sync).

check if a LINESTRING has at least one point as we
rely on that further.
The predicate is re-written from
((`test`.`g1`.`a` = geometryfromtext('')) or ...
to
((`test`.`g1`.`a` = <cache>(geometryfromtext(''))) or ...
The range optimizer calls save_in_field_no_warnings, in order to fetch keys.
save_in_field_no_warnings returns 0 because of the cache wrapper,
and get_mm_leaf() proceeded to call Field_blob::get_key_image()
which accesses un-initialized data.

If we have cached a null_value, then verify that the Field can accept it.
