Message:

Add GDALProxyDataset and GDALProxyRasterBand abstract classes to be able to make proxy datasets and raster bands; Add a proxy dataset class, GDALProxyPoolDataset, that differ at the maximum the opening of the underlying dataset and keep the number of simultaneous opened underlying datasets under a limit (similar to what is done in the RPFTOC driver)
