ADDED: Toggle Expand and Collapse all functionality with F12 key

[sharma-abhishek]

Kindly review expand and collapse all processes (toggle) functionality with F12 key.

Hi! Thanks for taking the time to write a PR! But what's the expected behavior? On Linux systems, this will collapse init and basically hide all processes. I'm afraid it doesn't sound too useful...

Hi hishamnhm,

It is actually an add-on to expand/collapse functionality which basically group all the child/worker processes into single entity (parent process). It will be of great use when the list of child processes are too long to fit in a console and user wants to scroll down to find the process quickly.

Hello @hishamhm , I can see what you're getting at, but I've verified by compiling that this pull request doesn't cause the issue you think it does. It collapses all processe trees except the init, so I thinks it can be merged into the next release.

Thanks @gsaga and @5shekel. Good to know that it’s working for you guys. Hoping to see this request merged soon.

further usage revealed a rough edge. start htop, click F12, all fold (aside from init), all good

but... in situation when

1. htop is already opened and folded
2. starting new processes - the new processes will not "auto-fold"
3. and hitting F12 again will not collapse the new guy, but only prior processes (not sure about which ones actually) tested on arch linux

Just tried on Arch Linux and initially nothing change, after few seconds it closes with PID abort (core dumped)

Same problem here, just compiled and ran htop on a Manjaro install, got "Aborted (core dumped)". Please help D=
