    rtpbin: remove use of ntp_ns_base

commit 5a4ecc9da1f73dc8b912b0cc49a59475478b7646

    rtpbin: remove more ntpnstime and cleanups

    Remove some code where we pass ntpnstime around, we can do most things with
the
    running_time just fine.
    Rename a variable in the ArrivalStats struct so that it's clear that this
is the
    current system time.

    rtpsource: use running_time for jitter

    Use the running_time to calculate the jitter instead of the ntp time. Part
of
    the plan to get rid of ntpnsbase.

    rtpbin: change how NTP time is calculated in RTCP

    Don't calculate the NTP time based on the running_time of the pipeline but
from
    the systemclock. This allows us to generate more accurate NTP timestamps in
case
    the systemclock is synchronized with NTP or similar.
