Diagnosing spurious wakes

This gist documents my attempts to get to the bottom of spurious wakes after installing Ubuntu 20.04 LTS on my system.

Initially, I thought it might be another system on my network sending Wake-on-LAN (WoL) packets. Then I thought it might be a known XHCI spurious wake kernel issue. And lastly, I finally resolved things by actively disabling the ability of USB devices, e.g. the mouse, to wake the system.

Update: I later came up with a better way of disabling wake-on-mouse that's covered here.

Note: as one of these steps, I upgraded the system BIOS - while this didn't resolve this particular issue, it did resolve an annoying issue with the graphic state not being properly restored for certain applications after wake-up.

 * A helper function expand_array for PHP

 * This is actually developed during the real need to develop JSON api
 * I wanted to have JSON api response spitted properly expanded (with semantic nodes)
 * But didnot want to do it by playing with arrays (looping, merging n' what not) time and again.
 * So, After fetching single dimensional array data from database, with keys having
 * some specific delimeter, this helper would do for me what i want to.
