Update Linux media handling (#1146)

* Enable CEF browser for Linux

* Disable the update for Linux, we don't have that one right now

* Update build_linux.yaml

We need  libpulse-dev for volume_catcher Linux

* Add linux_volum_catcher* files

* Enable OpenAL for Linux-ReleaseOS

* Linux: Update OpenAL

* Update SDL2

* Add libsndio-dev to the dependencies.

* Update CEF to an official LL version

* Remove dupe of emoji_shortcodes

* Reording autobuild does because it can and wants to

* Linux: Disable NDOF for the time being. After updating the ndof 3P needs to be rebuilt and we do not have a fresh one from LL yet.
Forcefully undefine LIB_NDOF, it gets defined in the build variables no matter if it is safe to define.

* Remove wrestling with mutliarch and LIBGL_DRIVERS_PATH

* Remove tcmalloc snippet, tcmalloc is a very faint bad dream of the past

* Putting out a warning this viewer ran on a x64 arch and then suggesting to install 32 bit compat packages makes no sense at all

* CEF resources need to be in lib

* It;'s okay to warn about missing plugins

* Linux: CEF keyboard handling

* Remove old gstreamer 0.10 implementation

* Linux DSO loading always had been very peculiar due to macro magic.
At least now it is peculiar shared magic with only one implementation.

* Remove -fPIC. We get that one from LL_BUILD

* /proc/cpuinfo is not reliable to detrmine the max CPU clock. Try to determine this by reading "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq".

Only if this fails go back to /proc/cpuinfo

* Cleanup

* Cleanup common linker and compiler flags, make it more obvious which flags are for which OS/compiler

* Switch to correct plugin file

* Install libpulse-dev for volume catcher.

* And the runner needs libsndio-dev as well.

* check for runner.os=='linux'. matrix.os is the full name of the image (limux-large).
