MDEV-6073 Merge gis test cases form 5.6.

        Tests were merged.
        As the implementation is different, the 'internal debugging' part
        was not merged, only a stub for it created.

+#
+# This is a shared file included from t/gis-precise.test and t/gis-debug.test
+#
+# - gis-precise.test is executed both in debug and production builds
+# and makes sure that the checked GIS functions return the expected results.
+# 
+# - gis-debug.test is executed only in debug builds
+# (and is skipped in production builds).
+# gis-debug.test activates tracing of the internal GIS routines.
+# The trace log is printed to the client side warnings.
+# So gis-debug.test makes sure not only that the correct results are returned,
+# but also check *how* these results were generated - makes sure that
+# the internal GIS routines went through the expected data and code flow paths.
