Another round of PostgreSQL 8.3 fixes, this time related to arrays. Make sure that we use the supplied ArrayType pointer macros, instead of attempting to access to cast directly to ArrayType. This resolved GBT#13 where a "corrupted histogram" error is thrown when using using ST_EstimatedExtent() under 8.3.

This was due to missing more VARSIZE macros in the PostgreSQL 8.3 conversion.

Changed the interface for the GEOS prepared predicates.
ST_contains, ST_containsProperly, ST_covers, and ST_intersects are now overloaded.
The new arguments style is ( geometry, geometry, integer). The third argument is used to determine when the first argument changes. The assumption is that when the third argument changes, the first argument is assumed to have changed too. This side-steps the issue of determining when the identity of the first geometry changes.

Tests for the prepared geometry predicates.
The tests were copied from regress_ogc, and modified.
Most of the tests use a pattern where the same function is invoked three times with the same argument.
This tests the prepared geometry caching mechanism.
This testfile haven't been added to regress/Makefile yet, as it fails for one case. This
probably due to a bug in GEOS.

Rewrite the pgsql2shp connection string code so that it uses a connection string, rather than setting environment variables. MingW-compiled and MSVC-compiled apps seem to have great problems passing the variables to each other, causing regression to fail. With this fix (and a Makefile tweak), it is now possible to run a MingW-compiled PostGIS against an MSVC compiled PostgreSQL and pass all regression tests.

Remove version numbers from liblwgeom references in lwpostgis.sql as per http://postgis.refractions.net/pipermail/postgis-devel/2007-September/002764.html.
