Title: gdal/ogr providers: optimizations and .zip / .gz file support - fixed

This request replace #109 which did not apply cleanly after applying other requests.

I have made a slight re-organization of the commits.

This pull request is part 3 of pull request 106 and adds optimizations for gdal/ogr dataset acces in the browser and adds support for access to files inside .zip and .gz files through gdal/ogr /vsizip and /vsigzip mechanisms (both in browser and normal file open).
