Modernize how many platform/network classes do isolatedCopy()

First part of this work was in https://bugs.webkit.org/show_bug.cgi?id=158293

Now let's get rid of these "CrossThread*Data" objects altogether.

other.m_allowCookies

Would it work to make a non-const asResourceRequest() instead of a const_cast here?

Yup yikes.

const_cast'ing the const ResourceRequest& is an already established pattern in the class.


The relationship between ResourceRequestBase and ResourceRequest is already so gnarly that I didn't feel like tackling that here.

Would be a good followup cleanup.

The linux build errors:

In file included from ../../Source/WebCore/platform/network/ResourceErrorBase.cpp:28:0:
../../Source/WebCore/platform/network/soup/ResourceError.h: In member function 'WebCore::ResourceError WebCore::ResourceErrorBase::isolatedCopy() const':
../../Source/WebCore/platform/network/soup/ResourceError.h:70:10: error: 'void WebCore::ResourceError::doPlatformIsolatedCopy(const WebCore::ResourceError&)' is private
../../Source/WebCore/platform/network/ResourceErrorBase.cpp:52:55: error: within this context

Funny, that method is private in the CF/Mac version as well, but it builds on Clang.

Anyways, yah I'll make it public.

(Normally I'd virtualize it, but we try to keep these classes non-virtual for some historic reason I forgot)

Oh duh:
    friend class ResourceErrorBase;


Will add to the other headers.

Last 500 characters of output:
p.o.d -o Source/WebCore/CMakeFiles/WebCore.dir/platform/network/FormData.cpp.o -c ../../Source/WebCore/platform/network/FormData.cpp
../../Source/WebCore/platform/network/FormData.cpp: In member function 'WebCore::FormDataElement WebCore::FormDataElement::isolatedCopy() const':
../../Source/WebCore/platform/network/FormData.cpp:139:1: error: control reaches end of non-void function [-Werror=return-type]

That's just GCC not recognizing that all 3 of the possible cases are handled. *sigh*
