evdev: export event device properties through sysctl interface A big security advantage of Wayland is not allowing applications to read input devices all the time. Having /dev/input/* accessible to the user account subverts this advantage. libudev-devd was opening the evdev devices to detect their types (mouse, keyboard, touchpad, etc). This don't work if /dev/input/* is inaccessible. With the kernel exposing this information as sysctls (kern.evdev.input.*), we can work w/o /dev/input/* access, preserving the Wayland security model.

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Permit sysctl(8) to set an array of numeric values for a single node. Most sysctl nodes only return a single value, but some nodes return an array of values (e.g. kern.cp_time). sysctl(8) understand how to display the values of a node that returns multiple values (it prints out each numeric value separated by spaces). However, until now sysctl(8) has only been able to set sysctl nodes to a single value. This change allows sysctl to accept a new value for a numeric sysctl node that contains multiple values separated by either spaces or commas. sysctl(8) parses this list into an array of values and passes the array as the "new" value to sysctl(2).
