Switch to using WebDragData in WebView and WebViewDelegate.

I also cleaned up some of the WebView and WebViewDelegate methods to pass
WebPoint instead of pairs of ints or gfx::Point.

With this change, I am keeping webkit/glue/webdropdata.{h,cc}, which is what
Chrome uses to pass around the equivalent data.  Now, it is possible to
construct a WebDropData from a WebKit::WebDragData and to also get a
WebKit::WebDragData from a WebDropData.  Hence, the conversion between
WebDropData and ChromiumDataObject (see clipboard_conversion.{h,cc}) is now
removed in favor of conversion between WebDropData and WebKit::WebDragData.

Conversion between WebKit::WebDragData and WebCore::ChromiumDataObject is very
cheap (just reference counting).

Finally, this change also brings in WebData, which is now used by the return
value of WebKitClient::loadResource.  As a companion to that change, I also
changed webkit_glue::GetDataResource to return StringPiece instead of
std::string.  That also saves on an unnecessary buffer copy.
