I can't help you with the first problem (POST file upload size). I don't know, but there may not be a way to do what you want with the HTTP protocol. Like you, I just wait for the upload_data_size to be 0. That may be all you CAN do given HTTP. (I honestly don't know.)
For your second question.. I use 'MHD_get_connection_values' to parse the query string. You give it a callback function and, if you need it, a void* pointer. (I'm using C++, but I use mine to store an unordered_map to put the key/value pairs in) In the callback, you get your given pointer plus the key and value from a single query string item. The callback gets called as many times as there are parameters. I think this function is what you're after. I'm sure there's documentation on it somewhere, but it's pretty straight forward to use after you get the hang of it.
