Add new os-build targets: rt-devel and automotive-devel
This is an attempt to automate the rt and automotive devel branches
using the upstream linux-rt-devel tree as the base combined with
os-build.
The overall process isn't too complicated but there are enough steps to
make it compilicated.
Steps:
* map upstream linux-rt-devel to master-rt branch
* update os-build
* grab linux version from master-rt and os-build
* if version the same then merge os-build and master-rt to
os-build-rt-automated
* else merge tag kernel-N.V.0-0 and master-rt to os-build-rt-automated until
master-rt is update to os-build
* merge os-build-rt-automated into os-build-rt-devel
* merge os-build-rt-automated into os-build-automotive-devel
* run the generate pending-rhel config scripts on rt-devel and
automotive-devel
The script has beginning logic to handle rebasing if necessary when the
rt-devel branch transitions from os-build-stable (linux-stable) to linux
master again.
NOTE: The script uses kernel-N.V.0-0 which is rebased after os-build
linux-x.y GA is created but before linux-x.y+1 pre-rc1 merges happen.
The reason for this is because linux-stable-x.y doesn't exist until
linux-x.y+1-rc1 exists thus leaving linux-stable-x.y-1 in the meantime.
An awkward gap exists, use kernel-N.V.0-0 as the base.
The script has no effect on the day-to-day operations of os-build. They
are designed to be run from a gitlab cron job and update in the
background. Once they are deemed stable, adding ARK MRs that target
either os-build-rt-devel or os-build-automotive-devel will be possible
and those branches can start proper parallel developement with os-build.
Cleanup namespace pollution because shellcheck doesn't like 'local'.
