aa4d4ff23c Frontends, VideoCore: Move glad initialisation to the frontend
On SDL2 this allows it to use SDL_GL_GetProcAddress() instead of the
default function loader, and fixes a crash when using apitrace with an
EGL context.

On Qt we will need to migrate from QGLWidget to QOpenGLWidget and
QOpenGLContext before we can use gladLoadGLLoader() instead of
gladLoadGL(), since the former doesn’t expose a function loader.

90243c56fb Merge pull request #1730 from hrydgard/vertex-loader
* Remove late accesses to attribute_config

* Refactor: Extract VertexLoader from command_processor.cpp.

Preparation for a similar concept to Dolphin or PPSSPP. These can be JIT-ed and cached.

* Move "&" to their proper place, add missing includes and make some properly relative.

* Don't keep base_address in the loader, it doesn't belong there (with it, the loader can't be cached).

* Optimize the vertex loader, nearly doubling its speed.

* Debugger fix

* Move and rename the MemoryAccesses class to MemoryAccessTracker.

254582aa35 OpenGL: Fix state tracking in situations with reused object handles
If an OpenGL object is created, bound to a binding using the state
tracker, and then destroyed, a newly created object can be assigned the
same numeric handle by OpenGL. However, even though it is a new object,
and thus needs to be bound to the binding again, the state tracker
compared the current and previous handles and concluded that no change
needed to be made, leading to failure to bind objects in certain cases.

This manifested as broken text in VVVVVV, which this commit fixes along
with similar texturing problems in other games.

1fe9b0b82e VideoCore: Fix values of unset components in input attribute arrays
If an input attribute array had a field with less than 4 components, the
remaining components were left unset if not specified by a default
vertex attribute. If neither mechanism would set a component, it would
assume a garbage value.

It has been verified that the hardware behavior is to instead to set the
missing components from the fixed default of (0 0 0 1). The default
vertex attribute values aren't used at all if a vertex array is
specified for that attribute.

Fixes UI graphics on Fire Emblem: Awakening, a small texturing glitch
when selecting a character in Cubic Ninja, as well as eliminating the
unset-W hack which was required for Ocarina of Time to not have
garbled triangles.

This change has been tested against hardware.
