That's the language id block, we're using LANGUAGE_EN for now. This block allows some games to boot further

It is now kept in memory as per 3dbrew, all updates happen on memory, then they can be saved using UpdateConfigNANDSavegame.

Seems to allow some games to boot further, thanks @Normmatt for sharing this information

Added a "config" file to the CFG process service (CFG:U), and added a few default blocks to it.

Implemented GetSystemModel and GetModelNintendo2DS

This is a first step at fixing the conceptual insanity that is our
handling of service and IPC calls. For now, interfaces still directly
derived from Session because we don't have the infrastructure to do it
properly. (That is, Processes and scheduling them.)

CFG:U: Store country codes as u16 instead of char pointers, and return the correct error in GetCountryCodeID.
