84718775a2 ass: avoid infinite unref loop with bad data 
A classic case of not updating the next item to iterate after deleting
it from the singly linked list.

Only ever hit with a text buffer with GST_CLOCK_TIME_NONE for either the
timestamp or duration.

ab12a4cd0f assrender: fix seeking backwards 
Use proper API to flush libass events when we do
a flushing seek, and also do it in FLUSH_STOP
rather than FLUSH_START, so we can be sure
streaming has stopped.

Fixes seeking back in time.

Something seems to have changed in libass that
renders the old manual way of flushing events
ineffective and libass then seems to ignore
timestamps that are older than the ones last
seen then if we do it the old way.

Fixes #916

eb6a1cf07e assrender: use subtitle segment to calculate running time for text 
Not the video segment. This just for correctness, shouldn't make
any difference in practice since we don't support external SSA yet.

bba33533ab assrender: fix multiple subtitles on screen simultaneously 
This fixes an issue with SSA/ASS subtitles, where subtitles
would fail to appear if there was already a subtitle on screen.

This was because `struct _GstAssRender` had a single
`GstBuffer *subtitle_pending` member.  This meant that
the assrender context could only be aware of one subtitle
at a time.

This patch changes the subtitle_pending member to a
linked list of pending subtitles.

The `gst_ass_render_chain_text` function no longer needs
to care about whether there are already subtitles pending,
it simply appends new subtitles to the list.

The `gst_ass_render_chain_video` function has been modified
to handle the list of pending subtitles.

Finally, the `gst_ass_render_pop_text` function has been
modified to pop the entire list of pending subtitles.

63853b7b0d assrender: don't send flush events on seeks 
It's for the upstream element driving the pipeline to
handle seeks and send flush events or not, filters
should not interfere here, otherwise downstream pads
could be flushing before upstream pads are flushing,
which can result in GST_FLOW_ERROR being sent instead
of GST_FLOW_FLUSHING when trying to forward sticky
events at just the wrong moment.
