8cacd54e8f compositor: fix off-by-1 error in blending ARGB 
Use a more naive blend formulation that avoids off-by-one errors
at the 0x00 and 0xff alpha endpoints.

    Fixes #810

3edf390b4c videorate/videoscale/audioresample: Ensure that the caps returned from fixate_caps() are actually fixated 
If there is some other field than the ones we care about left and not
fixated yet then basetransform will just error out. So instead just pass
the result through gst_caps_fixate() in the very end.

1ce61b1b08 tags: update to latest iso-code and support more languages 
Some languages have an ISO 639-2 representation but no 639-1
representation, for example where "eng" has a two-letter
equivalent in "en", "enm" doesn't have one.

Discarding those languages from our static table caused functions
such as gst_tag_get_language_code_iso_639_2T() or
gst_tag_get_language_code_iso_639_2B() to return NULL for
valid language codes such as "enm", potentially causing users
of these API such as mpegtsmux to discard language code tags
as invalid.

5ad727f9ee compositor: Frames where we introduce alpha can't obscure anything 
When a pad has alpha != 1.0 it means that the resulting frames will
contain alpha and thus can't fully obscure with a lower zorder.

Also simplifies the other checks as blending with an OVER or on a
transparent is not a no-op as previously assumed.

c2b9be5c94 glwindow/winrt: Increase timeout value to 15 seconds 
5 seconds might not be enough value for timeout in case an application
is running on a device with very limited computing power.
Note that ANGLE uses 10 seconds timeout value. So even if a timeout
happens here, it's also ANGLE's timeout condition as well
(meaning that bad things will happen either way)

607dc1d135 audioaggregator: Check all downstream allowed caps structures if they support the upstream rate

audioaggregator would then fail negotiation.

Also this now correctly handles downstream returning a range of
supported rates.

1cead20777 encodebin: Fix and refactor smart encoding 
It was not working properly and the implementation of the smartencoder
element was weird. This introduce a number of changes (which are all
in one single commit because they basically all work together and lead
to basically reimplementing the element):

* Make smartencoder a bin so that the reencoding chain of elements are
  inside of it instead of not having any parent. Those elements were not
  be visible when dumping the pipeline which was very confusing.
* Make encodebin create the right encoder with a capsfilter (and parser)
  to properly enforce the format specified by the user, and so that the
  encoder properties specified in the encoding profile are respected.
* Use `decodebin` to do the decoding instead of selecting a decoder
  ourself and not plug any parser etc...
* Ensure that negotiated format in the sinkpad of smart encoder is fixed
  through time when the user requested a non dynamic output
* Add a parser at the beginning of the smart encoder
* Handle errors when reencoding

e762f1b376 Revert "gstgldisplay: Add public foreign_display property" 
This introduced a possible regression where the EGL display connection
could be leaked when a foreign native display (x11, wayland, etc) could
create a non-foreign EGL display that would never be destroyed.

The underlying problem needed to be solved in a different way.  See
