encode: don't access ao->pts

This field will be moved out of the ao struct. The encoding code was
basically using an invalid way of accessing this field.

Since the AO will be moved into its own thread too and will do its own
buffering, the AO and the playback core might not even agree which
sample a PTS timestamp belongs to. Add some extrapolation code to handle
this case.
