externals: Update mbedtls to 2.16.9

core: Switch to unique_ptr for usage of Common::Fiber.

mbedtls 2.16 is the last version which has licensing for GPL 2.0. This updates mbedtls to our own fork of mbedtls 2.16

vk_command_pool: Reduce the command pool size from 4096 to 4

InputCommon: Use an unique client id for each udp socket instance

Network error handling reform

core: Shutdown: Move kernel cleanup to later in shutdown.

- Fixes a shutdown crash due to a race condition with GPU still accessing memory.

[Service::nifm] Fix bcat_backend's default initialisation

gpu_thread: Remove Async NVDEC placeholders

This commit removes early placeholders for an implementation of async nvdec. With recent changes to the source code, the placeholders are no longer accurate, and can cause a nullptr dereference due to the nature of the cdma_pusher lifetime.

`network.cpp` has several error paths which either:
- report "Unhandled host socket error=n" and return `SUCCESS`, or
- switch on a few possible errors, log them, and translate them to
  Errno; the same switch statement is copied and pasted in multiple
  places in the code

Convert these paths to use a helper function `GetAndLogLastError`, which
is roughly the equivalent of one of the switch statements, but:
- handling more cases (both ones that were already in `Errno`, and a few
  more I added), and
- using OS functions to convert the error to a string when logging, so
  it'll describe the error even if it's not one of the ones in the
  switch statement.
  - To handle this, refactor the logic in `GetLastErrorMsg` to expose a
    new function `NativeErrorToString` which takes the error number
    explicitly as an argument.  And improve the Windows version a bit.

Also, add a test which exercises two random error paths.

core: hle: ldn: Error out on call to Initialization.

HID: Implement gestures

common,video-core: unbreak GCC 11 build on FreeBSD 13

- Since we do not emulate LDN, returning an error here makes more sense.

- With using unique_ptr instead of shared_ptr, we have more explicit ownership of the context.
- Fixes a memory leak due to circular reference of the shared pointer.

Kernel Rework: Memory updates and refactoring (Part 1)

[OpenGL] Implement glDepthRangeIndexeddNV

acc: Stub GetNintendoAccountUserResourceCacheForApplication

This allows drivers to reuse memory more easily and preallocate less.

ci: Add clang build scripts

Adds scripts that instruct CI to build yuzu with the installed Clang
compiler on yuzuemu/build-environments:linux-fresh.

These scripts are based on the .ci/scripts/linux scripts, minus AppImage
building since that isn't necessary. Re-uses linux-fresh since that
container has Clang 12 installed.

Offsets for TexelFetch and TextureGather in Vulkan

Implements both SendVibrationGcErmCommand and GetActualVibrationGcErmCommand, and modifies GetVibrationDeviceInfo to account for additional controllers.

This command returns a Nintendo Account ID and writes 2 output buffers. The first output buffer is a NasUserBaseForApplication and the second output buffer is currently empty.

Used by:
- Pokken Tournament DX
- Super Smash Bros. Ultimate
- Super Nintendo Entertainment System - Nintendo Switch Online
- Mario Kart 8 Deluxe

kernel: Fix resource release exception on exit

After rewriting the resource limit, objects releasing reserved resources require a live kernel instance.
This commit fixes exceptions that occur due to the kernel being destroyed before some objects released their resources, allowing for a graceful exit.

gl_disk_shader_cache: Log total shader entries count on game load

common: wall_clock: Fix integer overflow with StandardWallClock.

- Previous optimized impl. resulted in an integer overflow, so revert.
- This is our slow/fallback path that should never be really be used, so the optimization in unimportant.
