Michael Drake 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.
