Video renderer restarted multiple times

Description

After investigation, the renderer restarts are triggered by multiple frame rate change events. Pjmedia learns remote frame rate by inspecting incoming RTP timestamp interval, when it detects frame rate is increasing, it will send PJMEDIA_EVENT_FMT_CHANGED event to application, in this case it is video port, which eventually will trigger video renderer restart. Unfortunately, some endpoints may send video RTP timestamps not in a fixed interval (even when the fps is fixed).

Fix #1876: Don't restart renderer when only fps is changing, just modify the clock instead.
