Stop slow transfers

By default, a transfer can stall or transfer data extremely slow for any period without that being an error.
Stop a transfer if below N bytes/sec during M seconds. Set N with CURLOPT_LOW_SPEED_LIMIT and set M with CURLOPT_LOW_SPEED_TIME.
Using these option in real code can look like this:
#include <stdio.h>
#include <curl/curl.h>
int main(void)
{
CURL *curl;
CURLcode res = CURLE_OK;
curl = curl_easy_init();
if(curl) {
/* abort if slower than 30 bytes/sec during 60 seconds */
curl_easy_setopt(curl, CURLOPT_LOW_SPEED_TIME, 60L);
curl_easy_setopt(curl, CURLOPT_LOW_SPEED_LIMIT, 30L);
curl_easy_setopt(curl, CURLOPT_URL, "https://curl.se/");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
return (int)res;
}
