Bborie Park c4305740bc Fixed incorrect use of rt_band_destroy when loading offline band data. ALso added rules to raster_columns and raster_overviews to gracefully handle insert/update/delete.

Bborie Park 35b0ff01ae Make the data of externally-loaded band internally owned so a call to rt_band_destroy() properly frees the memory.

Bborie Park 370bae1ed5 Add read-only support for band data located outside the database in raster files. All "get" and analysis functions should work for out of database bands. Related ticket is #1440. Also added a test raster file for use by an out of db band and future use for raster2pgsql loader regression tests.

Bborie Park 63e7bbcd67 Instead of using spatial reference text in WKT format, use PROJ.4 format when possible. This does mean that in situations that require WKT format, rt_raster_gdal_sr must be called to convert from one format to the other.

Bborie Park fce6e3a842 Added option -G to get listing of supported raster types instead of calling ST_GDALDrivers in SQL. Had to tweak rt_raster_gdal_drivers in rt_api.c to not limit drivers based upon creation capabilities. Associated ticket is #1374. 
Added ability to specify band indices with ranges for option -b.  Example: -b 1-5,7,9-15.  Associated ticket is #1375.
Added warning messages when loader is processing more than one raster and rasters may have different number of bands, pixel types, hasnodata flags, NODATA values, geotransforms andtile sizes.  Associated ticket is #153.

Bborie Park 8864196bef Changed rt_raster_has_no_band to use 0-based band index instead of 1-based. Removed function prototype ST_HasNoData(raster) as the other prototype ST_HasNoData(raster, nband) now uses the default value of 1 for nband.

Bborie Park a3abb76533 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). 
Associated ticket is #1174.

Bborie Park 295c02be84 Changed adjustment of extent by half-pixel to full-pixel for points and linestrings to ensure compatibility with GDAL 1.6, 1.7 and 1.8. GDAL 1.9 (current trunk) appears to work fine with half-pixel adjustments.
