Bug 103907 – Make MainResourceLoader not use m_frame directly

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Nate Chapin]

MainResourceLoader will soon cease to be a ResourceLoader subclass.  It currently makes extensively use of both m_documentLoader and m_frame from ResourceLoader.  By moving everything over to going through m_documentLoader, we reduce the number of members we have to add to MainResourceLoader in https://bugs.webkit.org/show_bug.cgi?id=49246.

Post-49246, MainResourceLoader will be nearly owned by DocumentLoader, so hopefully this change will make that relationship more clear.

This patch also removes all accesses of FrameLoader::activeDocumentLoader().  The activeDocumentLoader() should always be MainResourceLoader's m_documentLoader, so it seems silly to reach through the FrameLoader to get at it.

Great!

Even though it’s not a common pattern in our code today, we might consider using references rather than pointers in cases like this if the pointer is not allowed to be zero.
