WebCore:
        To fix <rdar://problem/5044366> we now pass a NSString
        representation of the URL extracted with _web_originalDataAsString
        instead of relying on [NSURL absoluteString] in the bridge

        * page/mac/WebCoreFrameBridge.h:
        * page/mac/WebCoreFrameBridge.mm:
        (-[WebCoreFrameBridge getData:andResponse:forURL:]):
WebKit:
        Modify subresourceForURL to take NSString argument 
        so we can avoid [NSURL absoluteString]

        * WebView/WebDataSource.mm:
        (-[WebDataSource subresourceForURL:]):
LayoutTests:
        Test for <rdar://problem/5044366> make sure we can create
        a WebArchive from a page with a partially decoded url.

        * webarchive/archive-with-unencoded-url-expected.txt: Added.
        * webarchive/archive-with-unencoded-url.html: Added.
