[patch] ST_Transform support for minimally-compliant geopackages

[Brad Hards]

Patch attached.

Basically this changes the lookup of proj4 parameters to try the normal
spatial_ref_sys table if we have it, otherwise to do a lookup in the
gpkg_spatial_ref_sys table, and then look up the authority / srid pair in our
list.

As a special case, if the SRID is not present in the gpkg_spatial_ref_sys
table, the SRID will be looked up assuming that it matches what we're using in
the master table (i.e. not using auth/auth_srid).

Note that the patch is missing a couple of test geopackages used for error
checking. They're not that large (only 30K each), but I'll only post those if
required.

Hi Brad,

I'm currently working so to implement your patch.
Could you kindly send to my private e-mail address both
gpkg_test_broken.gpkg and gpkg_test_extrasrid.gpkg files ?

thanks in advance,
Sandro
