No new tests; behavior is unchanged

* platform/network/ResourceHandleInternal.h:
(WebCore::ResourceHandleInternal::ResourceHandleInternal): remove
no-longer-needed fields.
* platform/network/soup/ResourceHandleSoup.cpp:
(WebCore::finishedCallback): remove this, and m_finished, which
we no longer need to explicitly track
(WebCore::statusWillBeHandledBySoup):
(WebCore::soupErrorShouldCauseLoadFailure): No longer needed;
SoupRequestHTTP's logic is now aligned with WebKit's.
(WebCore::gotChunkCallback): remove gotChunkCallback, which
is no longer needed
(WebCore::startHTTPRequest):
(WebCore::sendRequestCallback):
(WebCore::gotHeadersCallback):
(WebCore::contentSniffedCallback): merge the code from
gotHeadersCallback and contentSniffedCallback into
sendRequestCallback
* platform/network/soup/ResourceResponseSoup.cpp:
(WebCore::ResourceResponse::updateFromSoupMessage): move the
sniffing override logic here
