e7b962d9b5 alphacombine: Ignore all events coming from the alpha_pad 
As per usage of this element, everything from this pad is a
duplicate. Instead of implemented needless aggregation, simply
drop all events from this pad and let the one from the main stream
passthrough. Also stop proxying some queries from the alpha pad_too.

This fixes racy test failure:
- validate.file.playback.scrub_forward_seeking.opus_vp9-alpha_webm

0484d658a8 codecalphademux: Do not set a GstFlowReturn from a boolean 
This was a small overlook, gst_pad_send_event() returns a boolean,
so setting it into ret could confuse the flow combiner. Though,
it didn't bug, since both 0 and 1 are success (though 1 being
undefined).

35775f1aec codecalphademux: Remove eos flow return workaround 
It turns out that downstream returning OK after EOS is a bug in
multiqueue. As we moved to queue, we no longer have this issue.
Let's keep the code clean and just assuming that downstream will
keep returning EOS and allow convergence of flow.

ea08442699 codecalphademux: Fix handling of flow combine 
As the alphacombine is simplified to received matching pair of buffers,
we can't just stop streaming when we receive EOS from downstream. Due
to usage of queue, the moment we get this return value may differ.

Though, by continuing pushing, we override the last_flowret on the pad
which can make us miss that we effectively can combine all flow into
EOS.

4c4f031207 h265parse: don't invalidate the last PPS when parsing a new SPS 
This is a port of https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2019
to h265parse.

When a SPS is received then any previous PPS remains valid. So don't clear
the PPS flag from the parser state.

This is important because there are encoders that don't generated a PPS after
every SPS.

eb96f50c45 mxf: check EOS cond with any segment's flag 
The previous test was preventing the pad to be in EOS
when the segment position was greater than segment stop.
It ended up consuming all the data before getting in EOS.

Regarding GST_SEEK_FLAG_SEGMENT it seems to be
correctly handled later in the method.

because we don't check before each output packet.
