* Adds microphone controls on Linux via PulseAudio (PA) for several
points in
https://github.com/OpenVR-Advanced-Settings/OpenVR-AdvancedSettings/issues/43.
It can not be overstated how unsuited the public AudioManager API is for
using the PA API.
It can also not be overstated how undocumented and horrible the PA API
is. The PA way of doing audio is very unlike the Windows way of doing
audio, which the AudioManager is heavily influenced by.
Since I don't have a Linux machine I have not been able to personally
test this. https://github.com/feilen/ has graciously helped with
testing.
PulseAudio is very undocumented and not very widely used for what we
need outside of official utilities. As such there's most likely a better
way of doing things than I've done.
Additional information can be found at
https://github.com/username223/pulseaudio-device-changing.
The "complex" PA API is asynchronous. Since our current AudioManager is
running synchronously and would not work asynchronously (functions are
expected to return valid data on function return) it is necessary to
massage the PA API until it runs synchronously.
This is done with a general workflow of
1. Register a callback function (`pa_context_get_source_info_list()`,
for example).
2. Run the PA loop through `customPulseLoop()`. This will trigger
any registered callbacks. Sometimes a `void*` is passed through the
callback that can be used for custom data. `successCallback()` uses
this to set the success variable.
3. Run the callback function and do required work.
4. Return to original function, do work or return values.
It is not possible to run a `customPulseLoop()` inside of an already
running loop (inside a callback), as this will lead to a PA assert
error on runtime.
* fixed audio override key unset issues
* Add apt-transport-https to CircleCI config
CircleCI fails with

when attempting to get the LLVM key.
This is suspected to happen because of an update to the image.

chaperoneGeometryQuads was converted from an implicit pointer array to a
std::vector because the only thing the pointer array did was hide the
fact that it was an array.
Audio profiles are not currently activated due to SteamVR changes.
micVol has been changed to default initilize to 1.0f since that was
being applied in the settings load anyway.
Release log:
https://github.com/ValveSoftware/openvr/releases/tag/v1.9.16
```
Removed sync function. Saving of settings is controlled automatically by
the system now. All existing calls to Sync can be deleted. Calls to sync
using old APIs do nothing.
```
