An extremely rare case where, for numeric reasons bestM finds more inliers than ninliersMax. 
This RARE case causes memory corruption and a nasty seg fault.

Looks like we don't actually use them; when creating precompiled headers
with Visual C++, a dummy .cpp is created at build time.

This reverts commit fba72cb6, reversing
changes made to 02131ffb.

e.g. <opencv2/core/core.hpp> become <opencv2/core.hpp>

Also renamed <opencv2/core/opengl_interop.hpp> to <opencv2/core/opengl.hpp>

Made all STL usages explicit to be able automatically find all usages of
particular class or function.
