From: Christian Hesse Add LowSpeedLimit and LowSpeedTime configuration options to correspond to libcurl's CURLOPT_LOW_SPEED_LIMIT and CURLOPT_LOW_SPEED_TIME options. This allows, e.g., transfers behind corporate virus-scanning firewalls to survive the delays. Increasing the timeout may not be desirable in all situations; similarly, disabling the check prevents detection of disappearing networks. Adds a utility function, parse_positive_long(), which yields a positive (but not unsigned) long integer from a null-terminated string using strtol(). A string containing anything but a base-10 number will cause the function to return -1.
