... to cater for systems with unsigned time_t variables. - Renamed the functions to curlx_timediff and Curl_timediff_us. - Added overflow protection for both of them in either direction for both 32 bit and 64 bit time_ts - Reprefixed the curlx_time functions to use Curl_* Reported-by: Peter Piekarski Fixes #2004 Closes #2005
