Changes QMessageBox usages to warnings, as the problems they bring to
light are being safely handled by the application and do not warrant
something of the "critical" level.

Changes LOG_CRITICAL to LOG_ERROR for the same reason. Preferring ERROR
to WARNING as yuzu is denying loading of any guest applications after
checking for these conditions.

Moved logging the GL_RENDERER string into GetUnsupportedGLExtensions()
to make more clear that unsupported extensions were already being
logged. Makes placement of the logs easier to understand later, as well.

Changes the first message to not include the OpenGL version, as the
error is caused by OpenGL failing to load.

Adds a new check for OpenGL version 4.3. This will display a message
with a similar error as well as the GL_RENDERER string. Adds a CRITICAL
log message when triggered. This prevents a crash with yuzu trying to
use older OpenGL versions.

Modifies the unsupported extension message to output the GL_RENDERER
string in the message, as well as logging the string.

Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.

The interrupt handler contains a std::atomic_bool, which isn't copyable
or movable, so the special move member functions will always be deleted,
despite being defaulted.

This can resolve warnings on clang and GCC.

- This seems to cause softlocks in Breath of the Wild.

Hides all of the implementation details for users of the class. This has
the benefit of reducing includes and also making the fiber classes
movable again.

This can use a braced initializer to accomplish the same thing with less
code.

Allows building on clang to work again

Rather than have directly modified global state here, we can make it an
implementation detail and have an interface that changes are queried
through.

Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.

This also allows us to remove our dependency on Python.

Cleans up common so that we can enable warnings as errors.

Prevents bugs from occurring where the results of a function are
accidentally discarded

- Refactor so that SubmitGPFIFO and KickoffPB use shared functionality.
- Implement add_wait and add_increment flags.

- Log corrupted command lists, rather than crash.

* Rename to align with switchbrew

* Rename to align with switchbrew and remove gpu function that checks if clearing should be done.

- Used by Final Fantasy X/X-2 HD Remaster.

Prevents the compiler tripping up about Windows headers.

src/core/hle/service/nvdrv/devices/nvhost_nvdec_common.cpp:41:15: error: unused variable 'OutOfMemory' [-Werror,-Wunused-const-variable]
constexpr u32 OutOfMemory{static_cast<u32>(-12)};
              ^

MSVC lets us fine-tune catching expressions with no side-effects a
little more.

Allows our CI to catch more potential bugs. This also removes the
[[nodiscard]] attribute of IOFile's Open member function. There are
cases where a file may want to be opened, but have the status of it
checked at a later time.

It's deprecated in the language to autogenerate these if the destructor
for a type is specified, so we can explicitly specify how we want these
to be generated.

Prevents values from mistakenly being discarded in cases where it's a
bug to do so.

The API of VP9 exposes a WasFrameHidden() function which accesses this
member. Given the constructor previously didn't initialize this member,
it's a potential vector for an uninitialized read.

Instead, we can initialize this to a deterministic value to prevent that
from occurring.

These helper functions don't directly modify any member state and can be
hidden from view.

Resolves a few -Wmissing-initializer warnings.

Adds 1 async worker thread for every 2 available threads above 8

Fixes compilation on MSVC

* The web_service http request is now fixed on Windows (R) platform.
* The issue is due to a complicated race-condition in `httplib`, a detailed
  explanation is available at https://github.com/yhirose/cpp-httplib/pull/701
* A pending Pull Request on `httplib` has been applied to remedy the
  said race-condition.
* The socket availability check is removed due to a behavioral chice of
  `httplib` that a socket will not be created before any actual request
  is sent.

- Fixes a shutdown crash when we try to submit telemetry if there is a service issue.
