Problem : Text samples have variable length and therefore act
more like continuous samples whereas audio and video
act more like discrete samples. Since we use sample
start time, a cue event could be inserted after the
start time of the last text sample and never get
inserted as there are no more samples.
Change : After all streams have requested flushing, we make sure
to collect all remaining cue events from the sync point
queue and insert them into each stream.

In the cue alignment handler, instead of storing just one cue, store
a full queue. This will make it easier to handle text streams that
end before audio and text.

In the cue aligner, instead of storing the cue event, store a
stream data so that we don't need to know the stream index when
sending the cue event downstream.

To make it easier to understand what a video stream and a non
video streams is doing in the cue aligner, each stream type is
given their own functions.

Use a common hint for all stream states as the hint is always
updated when we get a new cue event. Cue events are only gotten
when be pass the hint, so there should only need to be one hint.

SyncPointQueue manages all cue points and returns aligned cue
points to the callers (CueAlignmentHandlers).
CueAlignmentHandler is responsible for aligning cues from different
streams. It uses SyncPointQueue internally to align / synchronize the
cue points.
