* Haydn: Part 1
Based on my reverse of audio 11.0.0.
As always, core implementation under LGPLv3 for the same reasons as for Amadeus.
This place the bases of a more flexible audio system while making audout & audin accurate.
This have the following improvements:
- Complete reimplementation of audout and audin.
- Audin currently only have a dummy backend.
- Dramatically reduce CPU usage by up to 50% in common cases (SoundIO and OpenAL).
- Audio Renderer now can output to 5.1 devices when supported.
- Audio Renderer init its backend on demand instead of keeping two up all the time.
- All backends implementation are now in their own project.
- Ryujinx.Audio.Renderer was renamed Ryujinx.Audio and was refactored because of this.
As a note, games having issues with OpenAL haven't improved and will not
because of OpenAL design (stopping when buffers finish playing causing
possible audio "pops" when buffers are very small).

* Address gdkchan's comments
This PR fix an issue introduced on last IPC rewrite PRs where some returned buffer size have to be explicit now.
`GetClientId` without an explicit buffer size return some garbage to the guest and then `nifm` service crashes because of a wrong ClientId. It's fixed now.
Horizon Chase Turbo and Doom regression are fixed now. (Probably some other games too)

This PR stub call IsFreeCommunicationAvailable since it's the same as call CheckFreeCommunicationPermission without a sets of an internal field.
I've fixed a wrong logic found while I'm checked the call by RE.
This fix#1883.
* Fix comments
This PR fixes a regression introduced in #1741. The actual implementation do the assumption of fences always exist and then registering the callback.
Homebrews may not use fences, so the code crashes when it try to register the callback.
* Interrupt GPU command processing when a frame's fence is reached.
* Accumulate times rather than %s
* Accurate timer for vsync
Spin wait for the last .667ms of a frame. Avoids issues caused by signalling 16ms vsync. (periodic stutters in smo)
* Use event wait for better timing.
* Fix lazy wait
Windows doesn't seem to want to do 1ms consistently, so force a spin if we're less than 2ms.
* A bit more efficiency on frame waits.
Should now wait the remainder 0.6667 instead of 1.6667 sometimes (odd waits above 1ms are reliable, unlike 1ms waits)
* Better swap interval 0 solution
737 fps without breaking a sweat. Downside: Vsync can no longer be disabled on games that use the event heavily (link's awakening - which is ok since it breaks anyways)
* Fix comment.
* Address Comments.
* am/gui: Implement Wake-up message.

* audout: Implement GetAudioOutBufferCount, GetAudioOutPlayedSampleCount and FlushAudioOutBuffers
This PR implement audout service calls:
- GetAudioOutBufferCount
- GetAudioOutPlayedSampleCount
- FlushAudioOutBuffers
The RE calls just give some hints about no extra checks.
Since we use a totally different implementation because of our backend, I can't do something better for now.
SetAudioOutVolume and GetAudioOutVolume are fixed too by set/get the volume of the current opened track, previous implementation was wrong.
This fix#1133, fix#1258 and fix#1519.
Thanks to @jduncanator for this help during the implementation and all his precious advices.
* Fix some debug leftovers
* Address jD feedback
This PR fix an issue I've made in #1688 which is enabled VR as default.
It could cause rendering issues in games when VR mode isn't used, as users have reported in Smash:
* am/lbl/hid/pctl: Enabled VR Rendering
This PR enable VR rendering on games which support it through the Toy-Con VR Goggles.
Please remember Ryujinx currently don't support console SixAxis sensor and for now, in some games, the view can't be moved.
Everything is implemented accordingly to RE:
- am: ICommonStateGetter: SetVrModeEnabled, BeginVrModeEx, EndVrModeEx.
- lbl: ILblController: SetBrightnessReflectionDelayLevel, GetBrightnessReflectionDelayLevel, SetCurrentAmbientLightSensorMapping, GetCurrentAmbientLightSensorMapping, SetCurrentBrightnessSettingForVrMode, GetCurrentBrightnessSettingForVrMode, EnableVrMode, DisableVrMode, IsVrModeEnabled.
- pctl: IParentalControlService: ConfirmStereoVisionPermission, ConfirmStereoVisionRestrictionConfigurable, GetStereoVisionRestriction, SetStereoVisionRestriction, ResetConfirmedStereoVisionPermission, IsStereoVisionPermitted.
- hid: IHidServer: ResetSevenSixAxisSensorTimestamp is stubbed because we don't support console SixAxisSensor for now.
Maybe we could add a setting later to enable or disable VR. But I think it's fine to keep this always available since you have to enable it in games.
* Fix permission flag check
* Address gdkchan feedback
* apm: Refactoring/Unstub service
This PR implement some IPC calls of apm service:
- nn::apm::IManager is fully implemented.
- nn::apm::ISession is fully implemented (close#1633).
- nn::apm::ISystemManager is partially implemented.
nn::appletAE::ICommonStateGetter have some calls which are just a layer of apm IPC calls. What we did in some calls was wrong, it's fixed now!
Everything is checked with RE.
* abstract Apm *Server as Thog requested
* abstract ISession and fix other classes

Co-authored-by: Emmanuel <nhv3@localhost.localdomain>
This fix a mistake I made during my original reimplementation of SurfaceFlinger by disabling async buffer.
This fix a memory corruption on Super Mario All-Stars 3D (Super Mario Sunshine & Super
Mario Galaxy now go ingame).
Thanks to @gdkchan for tracing the memory corruption.

* New policy change: PTC version now uses PR number
* hos/gui: Add a check of NCA program index in titleid
This add a check to `ApplicationLoader` for the last 2 digits of the game TitleId who seems to be the NCA program index.
We currently return the last index, instead of the lower one.
Same check is added to ApplicationLibrary in the UI.
I've cleaned up both file too.

* account: Implement IManagerForApplication calls and IAsyncContext
This implement:
- IManagerForApplication::EnsureIdTokenCacheAsync (accordingly to RE) but the Async task is stubbed.
- IAsyncContext interface (accordingly to RE).
- IManagerForApplication::LoadIdTokenCache (checked with RE, and stubbed).
I've tried some games but now they needs some `sfdnsres` calls, some other boots and crashes with other issues.
Maybe we should disable the connection somewhere to lets the game think we are offline. I have done many attempts, without success, but since the code is here now, it's better than nothing.
(I've cleaned up `using` of IGeneralService too)
Closes#629 and closes#630
* change AccountId
* Fix gdkchan's comments
* use CompletedTask
Changes:
Implement software surround downmixing (fix#796).
Fix a crash when no audio renderer were created when stopping emulation.
NOTE: This PR also disable support of 5.1 surround on the OpenAL backend as we cannot detect if the hardware directly support it. (the downmixing applied by OpenAL on Windows is terribly slow)
* Amadeus: Final Act
This is my requiem, I present to you Amadeus, a complete reimplementation of the Audio Renderer!
This reimplementation is based on my reversing of every version of the audio system module that I carried for the past 10 months.
This supports every revision (at the time of writing REV1 to REV8 included) and all features proposed by the Audio Renderer on real hardware.
Because this component could be used outside an emulation context, and to avoid possible "inspirations" not crediting the project, I decided to license the Ryujinx.Audio.Renderer project under LGPLv3.
- FE3H voices in videos and chapter intro are not present.
- Games that use two audio renderer **at the same time** are probably going to have issues right now **until we rewrite the audio output interface** (Crash Team Racing is the only known game to use two renderer at the same time).
- Persona 5 Scrambler now goes ingame but audio is garbage. This is caused by the fact that the game engine is syncing audio and video in a really aggressive way. This will disappears the day this game run at full speed.
* Make timing more precise when sleeping on Windows
Improve precision to a 1ms resolution on Windows NT based OS.
This is used to avoid having totally erratic timings and unify all
Windows users to the same resolution.
NOTE: This is only active when emulation is running.
* Logger class changes only
Now compile-time checking is possible with the help of Nullable Value
types.
* Misc formatting
