Add support for modifying SDO_GEOMETRY data.
(Support for RETURNING is still missing.)
Add oracleGetGeometryType() to get the OCIType of SDO_GEOMETRY.
Rename ewkbToGeom() to oracleEWKBToGeom() to be consistent with other exported functions.
Export oracleGeometryFree() and move it to oracle_gis.c.
Allocate SDO_GEOMTERY object in oracleEWKBToGeom(), make it handle NULL input right and fix a bug in setPoint() (looks like some bugs still remain).
Make sure that no memory is leaked with the object code by calling OCICacheFree() at the end of each transaction.
Remove execute permissions on Makefile.
