We had used conan for opus before, but there was a bug in the AVX detection.
However we still had the Findopus.cmake file within the repository, but not used.

This patch reenables the Findopus helper and prefer the system wide installation of opus.

nvhost_nvdec_common: Avoid memcpy with null pointers

svc: Expand SVC tables

service: fs: Update service function tables

nvhost_ctrl_gpu: Avoid sending null pointer to memcpy

service: acc: Update service function tables

common: Move assert failure handling into a cpp file.

process_capability: Handle extended SVC range

service: audio: Update service function tables

vp9: Avoid memcpy with null pointers

12.x expanded the range of SVC entries from 0x7F to 0xBF (with all new
entries being unused), so we can expand it to also match.

12.x extended the range of SVC IDs, so we need to expand the range of
bits that need to be tested.

The upside of this is that we can eliminate a range check, given the
whole range is used.

Avoid sending null pointer to memcpy as reported by Undefined Behavious
Sanitizer.

Undefined Behaviour Sanitizer reports a null pointer is being sent to
memcpy, thought it's "guaranteed to never be null". Guard it with an if
statement, and log when the action has been averted.

Avoid sending null pointer to memcpy as reported by Undefined Behaviour
Sanitizer. Replaces the std::memcpy calls in SpliceVectors with
std::copy calls. Opting to replace all the memcpy's with copy's.

configure_graphics: Prevent stack-use-after-scope

Advantage: Altering the handler does not need a full recompilation.
Disadvantage: noreturn is droped, so the caller is a bit slower.

We quite often run yuzu with a YOLO assertion handler. In fact, only very few
games run at all with asserts. This patch allows developers to patch the handler
without recompiling everything. The overhead of the missing "noreturn" attribute
shoul be negletable.

Address Sanitizer reports stack-use-after-scope on line 231
`vulkan_devices.push_back(QString::fromStdString(name));`. Instead of
using a pointer, copy the string into a std::string and use that,
instead.

ci: Fix MSVC build with CMake 3.20.0

InputCommon: Improve UDP communications

arm_dynarmic: Increase size of code cache

HID: Fix SL and SR buttons for right joycon

externals/cmake: Fix case spelling of libzip.

externals: dynarmic: Update to latest rev. to increase code size.

CMake is case senstive, so Libzip vs LIBZIP was a bug.
Upstream calls themself libzip, so let's pick this naming.

- The current limits are being hit in yuzu with some games.
- This should fix the slowdowns in newer updates for Super Smash Bros. Ultimate.

[test] arm_dynarmic: Always have a 'valid' jit instance

ISelfController: Stub SetAlbumImageTakenNotificationEnabled

Use a single connection for UDP server, make connection test longer and check all pads instead of only the first one

video_core: Accelerate ASTC texture decoding using compute shaders

yuzu/main: Add user command line argument
