Abstracts most of the input mechanisms under an InputSubsystem class
that is managed by the frontends, eliminating any static constructors
and destructors. This gets rid of global accessor functions and also
allows the frontends to have a more fine-grained control over the
lifecycle of the input subsystem.

This also makes it explicit which interfaces rely on the input subsystem
instead of making it opaque in the interface functions. All that remains
to migrate over is the factories, which can be done in a separate
change.

This doesn't modify member state, so it can be marked as const.

Supports the Left, Right, Middle, Backward and Forward mouse buttons.

This allows homebrew applications to be able to properly detect connected controllers.

The hardware tested value is 0.5 which translates to SHRT_MAX / 2

Normalizes the syntax used for attributes

This doesn't modify internal member state, so it can be marked as const.

LabelGLObject takes a string_view, so we don't need to make copies of
the std::string.

Avoids pulling in unnecessary things that can cause rebuilds when they
aren't required.

Add the necessary CMake code to copy the contents in a string source
shader (GLSL or GLASM) to a header file then consumed by video_core
files.

This allows editting GLSL in its own files without having to maintain
them in source files.

For now, only OpenGL presentation shaders are moved, but we can add
GLASM presentation shaders and static SPIR-V generation through
glslangValidator in the future.

This allows us passing any type of string and hinting the length of the
string to the OpenGL driver.

Simplifies code.

Removes the need for comments to indicate the fields being assigned.

We can convert these maps into constexpr arrays to eliminate some
runtime static constructors.

We can simplify a few loops by making use of ranged for.

Same behavior, minus unnecessary zeroing out of the pointer.

This constant is only ever assigned to downcount, which is a s64, not a
u64.

This is the only place it's actively used. It's also more appropriate
for web-related structures to be within the web service target.
Especially given this one doesn't rely on anything in the common
library.

Add an extra step in GPU initialization to be able to initialize render
backends with a valid GPU instance.

State track the current primitive topology with a regular comparison
instead of using dirty flags.

This fixes a bug in dirty flags for this particular state and it also
avoids unnecessary state changes as this property is stored in a
frequently changed bit field.

Migrates the Telemetry namespace into the Common namespace to make the
code consistent with the rest of our common code.

Avoids some trivially avoidable map lookups by keeping the result of
find operations around and querying them.

No external code makes use of this header, so we can freely change the
namespace.

This is a compiler/linker error waiting to happen.
