📄 Description

Added all stubs, added back all things that were already implemented, and added functions based on what my games called. I have some basic implementation of printf functions, but I'm not really satisfied with the implementation, so I only did the ones that are actually called by games, and will update the rest when I find a better solution (Also, the non string variants should interface with shadPS4's tty system as well). The new things are:
More math functions
More str functions
setjmp, longjmp (Driveclub needs it to work)
memmove

The main thing that needs implementing for Gravity Rush 2 (and probably other games as well) is the sceLibcMspace functions, which are their own memory management sublibrary, from what I can see.

Logs filtered by *:Critical Lib.LibcInternal:Info are welcome if they contain stubs

This probably won't help a lot of games go further without sceLibcInternal as LLE (though implementing sceLibcMspace might do that), and my only game that reached further was Driveclub.
