* Core: pass down Core::System reference to all services
This has to be done at once due to unified interface used by HLE/LLE switcher
* apt: eliminate Core::System::GetInstance
* gpu_gsp: eliminate Core::System::GetInstance in service
* hid: eliminate Core::System::GetInstance
* nwm: eliminate Core::System::GetInstance
* err_f: eliminate Core::System::GetInstance
There were a few places where nested namespace specifiers weren't being
used where they could be within the service code. This amends that to
make the namespacing a tiny bit more compact.
* kernel/event: Make data members private
Instead we can simply provide accessors to the required data instead of
giving external read/write access to the variables directly.
* fix compile error
The real kernel requires services to set up their static buffer targets ahead of time. This implementation does not require that and will simply create the storage for the buffers as they are processed in the incoming IPC request.
Static buffers are kept in an unordered_map keyed by their buffer id, and are written into the already-setup area of the request thread when responding an IPC request.
This fixes a regression (crash) introduced in #2992.
This PR introduces more warnings due to the [[deprecated]] attribute being added to void PushStaticBuffer(VAddr buffer_vaddr, size_t size, u8 buffer_id); and VAddr PopStaticBuffer(size_t* data_size);
