      Initialize offset for adaptive jitter buffer
      
      When the adaptive jitter buffer is enabled in sip.conf, the first frame placed
      in the jitter buffer fails with something like:
      
      jb_warning_output: Resyncing the jb. last_delay 0, this delay -215886466,
      threshold 1000, new offset 215886466
      
      This happens because the offset is not initialized before calling jb_put(). This
      patch modifies jb_put_first_adaptive() to set the offset to the frame's
      timestamp.
