Implement the rest of parameter type combinations of each spatial relation check
function using Boost.Geometry. Such combinations had to rely on old GIS algrithm
because the older version of Boost.Geometry lacked support for them.

We did so by calling Boost.Geometry algrithm functions directly if available,
or indirectly by implementing the check algorithms using other BG functions,
and we used boost.geometry rtree index as necessary for better efficiency.

Empty geometry collections are well supported as arguments for any
spatial relation check functions. Normal geometry collections are supported in
all spatial relation check functions except ST_Touches, ST_Overlaps and ST_Crosses.

Now no MySQL GIS relation check functions rely on old GIS algorithms anymore.

Implemented the following relation checks with an algorithm of O(NlogM) time complexity,
where N and M are the number of components of the multipoint and the other multi-geometry
respectively.

	multipoint disjoint multipolygon
	multipoint disjoint multilinestring
	multipoint within multipolygon
	multipoint within geometry-collection
