This change uses /proc/self/mounts to check if new devices are already

discover: Add struct load_url_result and load_task
Currently, load_url and load_url_async return a filename parameter and a
tempfile flag (indicating whether the file needs to be cleaned after

Instead, encapsulate this data in a struct load_url_result, which the
caller (and async callbacks) can read the status, filename and clean
parameters.
For internal use in load_url and helpers, we add a struct load_task to
hold a pointer to the load_url_result and async data.
