The result is EMPTY for a buffer(line, -1), but we still
need one FALSE operation to be stored in the condition.
And we actually add it but forgot to alloc memory to store it.
The Gis_point::init_from_wkt called the String::realloc(),
and this call is quite slow in the DEBUG mode. Which makes
loading the huge polygon hang forever.
Fixed by using the String::realloc(size, inc_size) version instead
as it's done for other spatial features.
Fixed the get_data_size() methods for multi-point features to check properly for end
of their respective data arrays.
Extended the point checking function to take a 3d optional argument so cases where
there's additional data in each array element (besides the point data itself) can be
covered by the helper function.
Fixed the 3 cases where such offset was present to use the proper checking helper
function.
Test cases added.
Fixed review comments.
The GIS WKB reader was checking for the presence of
enough data by first multiplying the number read (where
it could overflow) and only then comparing it to the
number of bytes available.
This can overflow and effectively turn off the check.
Fixed by:
1. Introducing a new function that does division only so
no overflow is possible.
2. Using the proper macros and parenthesizing them.
3. Doing an in-line division check in the only place where
the boundary check is done over a data structure other
than a dense points array.
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).

Problem:
lack of incoming geometry data validation may
lead to a server crash when ISCLOSED() function called.
Solution:
necessary incoming data check added.

We didn't implement an empty geometry. And returning NULL instead of it is not
quite correct. So here is the implementation of the empty value as GEOMETRYCOLLECTION().

If the result contains a polygon with a hole, consequitive shapes weren't calculated
properly, as the hole appeared as shape in the result, but actually it's a single shape
with the surrounding polygon. It's more natural to use the size of the result as
a border instead of the number of resulting shapes.
