The read callback declaration is as read_callback(void* buffer, size_t
size, size_t nmemb, void* stream). Say, the application might pass me
size as 10000 bytes, and I have to return to it this much data when the
read callback exits. I can not set a limit on the amount of data
read_callback requests.
