  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.
