gdal_translate can now add GCPs to image, gdalwarptest renamed

Folks,

I have modified gdal_translate to include a -gcp option for adding
GCPs to an image.

For instance, the following would add 4 GCPs that are sufficient to
rotate an image during the translation process.

gdal_translate -gcp 0 0 100 0 -gcp 512 0 100 100 -gcp 0 512 0 0 -gcp 512 512 0 
100 ~/openev/utm.tif out.tif

Then you could use gdalwarp to warp it.

Also, I have renamed gdalwarptest to gdalwarp (the new algorithm is now
the primary warper), and gdalwarp to gdalwarpsimple.  Only gdalwarp is
built and installed by default.

Best regards,
