jduncanatorandAc_K 5829e36a5c Audio: Properly implements audio fallback for SoundIO (#500)
* Audio: Properly implements audio fallback for SoundIO

Given some drivers have issues with SoundIO (for the time being), this attempts to detect if SoundIO can open the default audio device, and then return false in IsSupported if it can't.

* Audio: Handle the backend disconnected event

libsoundio panics by default when a backend disconnects, this catches that event and gracefully handles it.

* Audio: Fix styling nits

* Audio: Fix nits

Because Ac_K. 😫

jduncanatorandAc_K 8275bc3c08 Implement libsoundio as an alternative audio backend (#406)
* Audio: Implement libsoundio as an alternative audio backend

libsoundio will be preferred over OpenAL if it is available on the machine. If neither are available, it will fallback to a dummy audio renderer that outputs no sound.

* Audio: Fix SoundIoRingBuffer documentation

* Audio: Unroll and optimize the audio write callback

Copying one sample at a time is slow, this unrolls the most common audio channel layouts and manually copies the bytes between source and destination. This is over 2x faster than calling CopyBlockUnaligned every sample.

* Audio: Optimize the write callback further

This dramatically reduces the audio buffer copy time. When the sample size is one of handled sample sizes the buffer copy operation is almost 10x faster than CopyBlockAligned.

This works by copying full samples at a time, rather than the individual bytes that make up the sample. This allows for 2x or 4x faster copy operations depending on sample size.

* Audio: Fix typo in Stereo write callback

* Audio: Fix Surround (5.1) audio write callback

* Audio: Update Documentation

* Audio: Use built-in Unsafe.SizeOf<T>()

Built-in `SizeOf<T>()` is 10x faster than our `TypeSize<T>` helper. This also helps reduce code surface area.

* Audio: Keep fixed buffer style consistent

* Audio: Address styling nits

* Audio: More style nits

* Audio: Add additional documentation

* Audio: Move libsoundio bindings internal

As per discussion, moving the libsoundio native bindings into Ryujinx.Audio

* Audio: Bump Target Framework back up to .NET Core 2.1

* Audio: Remove voice mixing optimizations.

Leaves Saturation optimizations in place.

jduncanatorandgdkchan c1b7340023 Timing: Optimize Timestamp Aquisition (#479)
* Timing: Optimize Timestamp Aquisition

Currently, we make use of Environment.TickCount in a number of places. This has some downsides, mainly being that the TickCount is a signed 32-bit integer, and has an effective limit of ~25 days before overflowing and wrapping around. Due to the signed-ness of the value, this also caused issues with negative numbers. This resolves these issues by using a 64-bit tick count obtained from Performance Counters (via the Stopwatch class). This has a beneficial side effect of being significantly more accurate than the TickCount.

* Timing: Rename ElapsedTicks to ElapsedMilliseconds and expose TicksPerX

* Timing: Some style changes

* Timing: Align static variable initialization

jduncanatorandThomas Guillemard 76a3172f17 Asynchronously log messages to the Console window (#395)
* Logging: Asynchronously log messages to the Console window

Writing to the Console blocks until the write completes. This has the potential to block any code path that logs to the application logger.

By queuing up log messages in an asynchronous queue and returning without blocking, we can speed up code paths that heavily log to the console (for example stubbed services like ServiceHid).

From testing this results in a roughly 8% time decrease between Ryujinx startup and the splash screen in Super Mario Odyssey on my system - 00:03:19.591 down to
00:03:04.354. Depending on your system, YMMV.
