* 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.

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.
Looping through the vectors was done for almost all vectors
individually. Because there are some weird off by one issues that could
crop up it's easier to just have a function for it.
Passing a C style string (const char*) to any of the templated functions
would lead to a compile error. It was necessary to wrap the raw string
in a std::string call, which is obviously not ideal.
Using automatic type deduction was necessary because `std::vector<const
char*` is not the same as `std::vector<std::string>`.
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.
```
As of SteamVR 1.10.1 the overlay width feature has been implemented by
Valve in the standard settings.
OpenVR features related to overlay translation have been removed and the
main reason for including them (multi monitor setups) have been solved
by Valve giving each screen an individual overlay.
Enabling the switch on release builds will optimize the binaries as
normal, but will still include debug symbols. This is advantageous for
bugs that do not show up in debug builds without optimizations.
Due to the SettingsController being a static object it will be
initialized before the main method has been run. This will cause
easylogging to log using the default logging style instead of the
defined application style. Because of this the settings are propogated
up through a function into the main method.
The `customTickRateMs()` function is being called every millisecond,
adding the verification to every call leads to unnecessary overhead.
The tick rate is verified when loading and when saving.
After looking at the assembly output it became apparent that the Windows
compiler did not compile out the `getSettingsController()` function
call.
This led to an unnecessary function call in order to get the
SettingsController. Turning it into a static object in the compilation
unit scope removes this function call and turns getSettings call into a
single instruction (not counting zeroing the register for comparison and
the jump instruction afterwards).

Adding the following code to the `main` function:
```cpp
f ( settings::getSetting( settings::BoolSetting::UTILITY_vrcDebug ) )
{
LOG( INFO ) << "Enabled";
}
else
{
LOG( INFO ) << "Disabled";
}
```
Leads to this with the `getSettingsController` function:
```assembly
[...]
47 if ( settings::getSetting( settings::BoolSetting::UTILITY_vrcDebug ) )
0x7ff6c96819a0 <+ 1024> call AdvancedSettings!settings::getSettingsController (00007ff6`c96cd280)
0x7ff6c96819a5 <+ 1029> xorps xmm0,xmm0
0x7ff6c96819a8 <+ 1032> cmp byte ptr [rax+5FCh],0
0x7ff6c96819af <+ 1039> je AdvancedSettings!main+0x4fd (00007ff6`c9681a9d)
49 LOG( INFO ) << "Enabled";
0x7ff6c96819b5 <+ 1045> mov qword ptr
[rsp+288h],r15
0x7ff6c96819bd <+ 1053> mov qword ptr
[rsp+290h],rsi
[...]
```
And this without the function:
```assembly
[...]
47 if ( settings::getSetting( settings::BoolSetting::UTILITY_vrcDebug ) )
0x7ff7d97a19bb <+ 1019> xorps xmm0,xmm0
0x7ff7d97a19be <+ 1022> cmp byte ptr [AdvancedSettings!settings::settingController+0x5fc (00007ff7`d9854d4c)],0
0x7ff7d97a19c5 <+ 1029> je AdvancedSettings!main+0x4f3 (00007ff7`d97a1ab3)
49 LOG( INFO ) << "Enabled";
0x7ff7d97a19cb <+ 1035> mov qword ptr
[rsp+288h],r15
0x7ff7d97a19d3 <+ 1043> mov qword ptr
[rsp+290h],rsi
[...]
```
Notice the missing `call AdvancedSettings![...]` without the function
and that the settings call literally cannot be made any faster.
