I think we're trying to avoid the similar internal representation and operations that are needed for BlobBuilder and FormData, i.e., append operations. This is what this patch is about.

For copying between FormData/Blob and the network stack, it might be more efficient if we can share the same structure for the element list part, that is, FormDataElement vs. WebHTTPBody::Element. What I mean is that the element list is same and can be shared between these two, while each of them has its own specific members. FormData has "identifier" and Blob has "contentType" and "contentDisposition". We could have another patch for this purpose.
