Input: add userio module
Debugging input devices, specifically laptop touchpads, can be tricky without having the physical device handy. Here we try to remedy that with userio. This module allows an application to connect to a character device provided by the kernel, and emulate any serio device. In combination with userspace programs that can record PS/2 devices and replay them through the /dev/userio device, this allows developers to debug driver issues on the PS/2 level with devices simply by requesting a recording from the user experiencing the issue without having to have the physical hardware in front of them.
