* act: Add more command names and implement GetErrorCode
The command names have been extracted from 3dbrew and the JavaScript
bindings that the NNID settings uses internally.
The error names have been extracted from the Wii U implementation
(102-XXXX), which are compatible with the 3DS ones except for 022-5XXX,
which are error codes specific to the 3DS.
* act: Split error codes into separate file
* kernel: Switch to atmosphere style macros
* code: Rename ResultCode to Result
* code: Result constants are lower case
* Address review comments
* core: Remove CASCADE_CODE
* R_TRY replaces completely
* core: Run clang format
* 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.
