Make CheckSpatialMetaData() to check also GPKG

[Jukka Rahkonen]

Hi,

I wonder if the CheckSpatialMetaData() function could be made to return something else than "0" if the database is actually a GeoPackage. At the moment this function can only tell that the database is not a Spatialite nor a FDO database but a second request with CheckGeoPackageMetaData() must be performed for checking if it happens to be a GeoPackage. If would be more convenient to get this info also directly from CheckSpatialMetaData().

Hi Jukka,

now CheckSpatialMetaData() will return the following values:

0 - unrecognized db layout
1 - legacy SpatiaLite (<= 3.x)
2 - FDO/OGR
3 - current SpatiaLite (>= 4.x)
4 - GPKG

(already committed into the Fossil repository)
