LIB: Revert all commits to LIB folder and friends.

I had SOD playing music, and BT audio stream is broken,
cant stream to my car stereo.

need to test if ok after revert.

Lib folder is sensitive, it's connected every where, so updating
only 3 files inside will bring instability to all system.

best not mess with this folder, or update all connected to it.
and it's will be A LOT!
