Use the better understandable alias CURLOPT_HTTPHEADER in debug output
Bug fix - finally!
This fixes a bug I've been looking for a week.
By accidently calling get_clock_count() for the mTimeoutLowSpeedClock
'event', the time difference 'now' - 'event' becomes negative, which
should be impossible; the result being that timeout_low_speed
stalled for 24 seconds while looping over the full 32 bit. That in
turn made SSL handshakes of libcurl fail, which seemed to be
impossible since the calls to libcurl had not changed!
