MDEV-60 Support for Spatial Reference systems for the GIS data.

Browse Source 
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.
