- 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.

Followed pattern set out by texture streaming so that each chunk of audio data resides in its own bulkdata struct. It is currently possible to split audio into chunks when SoundWaves are marked for streaming but there is no way of doing this exposed at present.
Changed the parameters of FAudioDevice::GetRuntimeFormat so that the relevant SoundWave must be passed in, to allow for different formats for individual sounds/streaming options.
USoundWave::FreeResources no longer resets the NumChannels as it is unnecessary and causes sounds to be unable to play after the OGG data is flushed when attempting to switch to OPUS.

- Catching up with MatthewG's changes on other platforms.
- Fixes problems on QA-SoundLoop and elsewhere (TTP #334227).
