Force non Chunked uploads
Force non Chunked uploads

I spent a day figuring this out. WMF's wikis don't do HTTP/1.1,
so no chunked upload. Of course, you need chunked upload if you
do not know the length of your payload upfront. Oh well. So now
we have much higher memory requirements on the client side. Yay!
