As per Bryce's comments in ticket #1174 , reduce the number of calculations when doing rt_raster_geopoint_to_cell by using an inverse geotransform matrix. Unlike the patch attached to the ticket, this commit does not change the structure of the rt_raster struct. It may be worth changing the rt_raster struct eventually, but will cost us the single memcpy when serializing rt_raster. Also, changes for testing SRID as "unknown" if value is lte SRID_UNKNOWN (presently 0).

Had to update testapi.c as the geometries generated differ depending on whether or not GDALFPolygonize is used.

Added support for coverage tables to ST_Histogram. This entailed adding the ability to explicitly specify the min and max values in the underlying C function rt_band_get_histogram. The min and max parameters should ONLY be used by the established coverage table handling ST_Histogram functions as the returned percent element of the histogram type is changed from returning the percentage to returning the sum of counts for that histogram.

Changes in raster memory management:
...
- Only calling function memory context is used, except in SRF functions, where
multi_call_memory_ctx is used.
- rt_context internals hidden. The memory management and error reporting is
performed by rtalloc/rterror family functions. They simply call rt_context
struct fields as requested. Same philosophy here than in liblwgeom.
- Now rt_context memory is statically allocated. Before this, new memory for
rt_context was allocated in every function call. And the memory was allocated
outside the calling function (in fcinfo->flinfo->fn_mcxt postgres memory
context).
