Variable dload_interrupted is used both to abort a download because SIGINT was caught, and when a file limit is reached. But raising SIGINT is only meant to happen in the first case.

Upon receiving SIGINT a flag is set to abort the (curl) download. However, since it was never reset/initialized, if a front-end doesn't actually exit on SIGINT, and later tries any operation that needs to perform a new download, said download would always get aborted right away due to the flag not having been reset.

I think set_handle_opts is the wrong place to reset it since it is in fact not a handle option. Let's put it right before the signal handlers are registered to keep signal-related things together.
