[Phone] Please enable opus audio codec support in qtmultimedia

Hi, as described in QTBUG-50567 , qtmultimedia doesn't support opus
audio codec so for example we cannot record Telegram voice messages (
bug #1460464 and bug #1375179 ).
I patched qtmultimedia adding the support for audio/x-opus codec
through opusdec encoder in qtmultimedia, then I found qtmultimedia
5.4.1 (shipped with Ubuntu Phone vivid) is built against gstreamer0.10
and, as gstreamer0.10-plugins-bad packages is not installed by
default, opusdec encoder is not available.
I'm working on this bug, I created it to track the progress, in order
to add opus support I have to:
1 - create a new gstreamer0.10-opus package containing only the
opusdec plugin: I don't know whether I have to create a new source
package containing opusdec sources or only a new .deb package
(generated from gst-plugins-bad0.10 sources). I'm working on the
latter as gst-plugins-bad0.10 package requires work in any ways.
2 - properly patch qtmultimedia source, I'm attaching a
working-but-needs-cleanup patch. I think some opus declarations in the attached
patch can be avoided, but I haven't had time to work on it so I'm attaching the
patch I tested (requires gstreamer0.10-plugins-bad).
I don't know if qtmultimedia xenial/yakkety versions requires the patch too,
I haven't checked them yet.
