Given we now have the kernel as a class, it doesn't make sense to keep
the current process pointer within the System class, as processes are
related to the kernel.

This also gets rid of a subtle case where memory wouldn't be freed on
core shutdown, as the current_process pointer would never be reset,
causing the pointed to contents to continue to live.

Ensures that the cache always has a deterministic initial state.

GetHandle() internally calls GetHandle() on the stream_buffer instance,
which is a const member function, so this can be made const as well.

Implicit conversions during construction isn't desirable here.

Without this, the header file won't show up by default within IDEs such
as Visual Studio.

The only reason this include was necessary, was because the constructor
wasn't defaulted in the cpp file and the compiler would inline it
wherever it was used. However, given Controller is forward declared, all
those inlined constructors would see an incomplete type, causing a
compilation failure. So, we just place the constructor in the cpp file,
where it can see the complete type definition, allowing us to remove
this include.

Orders the elements in the initializer list in the order they're
specified in the class. This prevents compiler warnings about
initialization order.

romfs.h doesn't need to be included in the header, the only real
dependency here is common's swap.h that needs to be included.

These includes were previously being satisfied indirectly.

IMO the old code is fine, but nvidia raises shader compiler warnings.
Trivial fix through...

This is called ~3k times per frame in SMO ingame.
My laptop spends ~3ms per frame on allocating and freeing this string.

Let's just stop printing this kind of redundant information.

Orders the elements in the sequence to match the order in which they'll
actually be initialized in.

This patch caches VAO objects instead of re-emiting all pointers per draw call.
Configuring this pointers is known as a fast task, but it yields too many GL
calls. So for better performance, just bind the VAO instead of 16 pointers.

The idea of this cache is to avoid redundant uploads. So we are going
to cache the uploaded buffers within the stream_buffer and just reuse
the old pointers.
The next step is to implement a VBO cache on GPU memory, but for now,
I want to check the overhead of the cache management. Fetching the
buffer over PCI-E should be quite fast.

Now display correct error instead of catch-all MissingProgramNCA

Mainly, from control.nacp metadata instead of cnmt metadata

Fixes base game read errors

Right now only includes Updates, but should eventually contain all of the other patches we need.
