Mark Cave-Ayland d1a81c7b79 Add support for the upcoming release of PostgreSQL 8.3. From PostgreSQL 8.3, the internal structure of varlena datatypes has changed and so any references to the size of the varlena and its address must use the VARSIZE and SET_VARSIZE macros. Includes a #define in pgsql_compat.h so that SET_VARSIZE still works with the older PostgreSQL versions. Passes all regression tests under PostgreSQL 8.2 and PostgreSQL 8.3. Thanks to David Techer and Michael Fuhr for additional testing.

Mark Leslie 5624dc6444 Added curve handling to getType, numGeometries, geometryN, dimension, exteriorRing, numInteriorRings, interiorRingN, closed (lwgeom_ogc.c) lwgeom_clone (lwgeom.c) and area. Added function ST_CurveToLine and ST_LineToCurve. Added regression tests for sql-mm geometries and related functions.

Paul Ramsey c2f4b4695a Fix for enforceRHR to actually enforce rather than just reverse. (Note 
that seems to be enforcing CW RHR rather than CCW RHR.)

Sandro Santilli b0bd31e6f8 Fixed bug in SnapToGrid() bbox computation. 
Previous policy (WHEN SIMPLE) turned out to be non-simple,
so this has been changed to TAINING.
Bbox will then be recomputed by scanning output coordinates
iff input had a bbox cache.
AUTOCACHE_BBOX define (the default) will still force a
computation of output box if worth it.
Regress tests added for the case reported on postgis-users

Run of regress tests do not require postgis install
anymore. The library build in source tree will be
used for this purpose.

Version bumped to 1.1.2 and CHANGES file updated.

Sandro Santilli 4bca418336 Moved PG_LWGEOM WKB I/O and SRID get/set funx 
from lwgeom_api.c to lwgeom_pg.c.
Made lwgeom_from_ewkb directly invoke grammar parser rather then invoke
the PG_LWGEOM-specific function.
Cleaned up signedness-related and comments-related warnings for the files
being committed (more to do on other files)

Sandro Santilli a3e8fcf09a Forced copy of BOX2D at deserialization time. 
LWGEOM (sub)objects will always have their own copy, safely released
by lwgeom_release(). This will remove memory alignment problems.
