Patch by Jesus Sanchez-Palencia <jesus.palencia@openbossa.org> on 2011-09-21
Reviewed by Andreas Kling.

Source/WebCore:

Refactored QNetworkReplyHandler::finish() in order to add
and use the static function QNetworkReplyHandler::errorForReply().
This will be used by our Download implementation in WebKit2 (WebProcess)
when handling ResourceError.

* platform/network/qt/QNetworkReplyHandler.cpp:
(WebCore::QNetworkReplyHandler::finish):
(WebCore::QNetworkReplyHandler::errorForReply):
* platform/network/qt/QNetworkReplyHandler.h:
* platform/network/qt/ResourceRequest.h:

Source/WebKit2:

We implement the necessary functions of Download.h, and our QtFileDownloader
to handle all network communication and call the necessary functions of Download.

We use the download policy for any MIME type not supported by WebKit. This
behaves like Qt non-WebKit2 except that we don't force download when
we encounter Content-Disposition: attachment. We still use the "filename="
field for file name suggestion though.
