- The code that handles initial setup (command line processing, rlimits and debugger) is now shared between engine, UFE and SlateViewer.

- Added stubs per platform in their ini file that doesn't change volume, except for mac which this bug is about and for which I reduced the volume by -6 dB. This can be changed by designers as per needed for their game per platform. The final headroom should be set by designers.
- Removed the hard-coded headroom constant used in OpenAL recently added.

- 3d audio was fundamnetally broken in HTML5 and Linux for a long time (probably since original port from UE3)
- Fix is to do 3d spatialization math the same way we do it on XAudio2 (i.e. transform to listener-space then do relative source position from there)
- Since HTML5 and Linux *both* use nearly identical OpenAL implementations (and Linux has been fixed by users for a few issues), I decided to nuke the HTML5 implementation and instead link to the Linux implementation. Not sure if we should move the linux OpenAL implementation to a different folder, but it turned out not to matter for packing and testing HTML5
- Also went ahead and added a -3dB headroom factor to reduce volume overall with OpenAL implementation since it was louder than the XAudio2 implementation. I didn't do any technical measurements to come up with this headroom factor, just ear-balled it. We can do something more precise if needed.
- Tested this fix using a simple test-map of a single looping sound source. It was obviously broken (i.e. not panning) and is now obviously fixed.

- Contributed by slonopotamus.
- HardwareDevice can be null if the initialization (e.g. alcOpenDevice()) fails.

- Created audio device manager which manages weak ref handles to audio devices
- Audio device handles are created with WorldContexts and accessed through UWorld objects
- All access to audio devices are now through audio device handles
- There is a main/default audio device for GEngine for use with the Editor and single worldcontext games

Removed GVolumeMultiplier and added an equivalent to FApp to contain the code to load the unfocused volume multiplier from config.
UE-4449 - Allow users to choose whether audio can be heard when focus is lost

New files added to contain FVorbisAudioInfo and FOpusAudioInfo, added all necessary includes
Added a few more checks for whether the target platform supports audio streaming where appropriate
Moved #define to .h file as it was being used in two .cpp files (working because of unity build)

Duplicate ResourceID would have caused the same problems in HTML5 and Linux as Android. Other duplications are errors waiting to happen, there are a couple of stats functions that could be using the base class versions and not displaying the correct information.

Moved most of the contents of FAudioDevice::FreeResource to USoundWave::FreeResources so that we can be sure that all memory is cleared up during teardown.
Removed FreeResource function from some subclasses of audio device, as they weren't doing anything different than the base one.
Also removed ListSounds function from these same classes as that seems to have fallen behind current base class version and isn't used anyway.
Removed platform specific audio buffer storage so that there isn't confusion about which is being used and ensured that casts are used when necessary.
Fixed compile issue with STAT_AudioResourceCreationTime for HTML5.
