[Qgis-developer] WCS and Raster improvements for QGIS

This should be rather easy to add. It is just a matter of setting the right
option to CPLHTTPFetch() (and thus the curl library), namely :

<li>PROXY=val, to make requests go through a proxy server, where val is of the
    form proxy.server.com:port_number
<li>PROXYUSERPWD=val, where val is of the form username:password

Note: They can also already be used by setting the GDAL_HTTP_PROXY and
GDAL_HTTP_PROXYUSERPWD configuration options/environmenet variable, which will
act on all GDAL/OGR drivers that go through the CPLHTTPFetch() function.

I see Radim is already a GDAL committer, so there shouldn't be too much overhead
if he wants to hack in the WCS driver.
