📄 Description

This PR partially implements sceSysmoduleGetModuleInfoForUnwind by calling sceKernelGetModuleInfoForUnwind and returning any errors that throws. I've avoided handling whatever internal struct libSceSysmodule uses here, since the struct seems to be somewhat different from the kernel's module info struct based on what I've decompiled, and the old return 0 behavior was working fine enough before.

Allowing this function to pass along errors fixes libc spamming sceKernelGetModuleInfoForUnwind calls with invalid addresses, fixing random crashes in Unity games caused by libc accessing invalid memory during exceptions.
