cubicweb #878283 configurable max upload size and properly warn user [resolved]

I have a CW form with a file upload field. If I try to upload a large file (in my case 143MB), nothing happens during ~8 minutes and then the browser says the connection was reset.

During that time, the browser eats almost no CPU or memory, nor does CW.
