mcd r19

Started from scratch with clean kernel bases, reviewed and fixed commits from the past to archive a clean balanced kernel base which supports as much ROMs as possible. The build_kernel.sh script has also been added, so you now have everything you need to build this kernel yourself, since I'm retiring from Android after this release. It was a great time :)

As always: Stay safe, be kind and enjoy!
