[RFC] dropping of $(AUTORELEASE) feature

[Felix Fietkau]

Hi,

I have another idea that might simplify the mess of dealing with 
PKG_RELEASE handling.

1. we use AUTORELEASE for all packages in master
2. when creating a release branch, all PKG_RELEASE lines are changed to 
something like 22.03-1
3. we write a script that can automatically edit a series of local 
commits and for each commit:
   - figures out affected packages
   - edits each affected makefile to bump PKG_RELEASE
   - adds a Updated-Packages: <...> tag to indicate which packages it 
has changed (or 'none' if no packages were affected)
4. we ask people submitting patches via email or PR to not update 
PKG_RELEASE themselves anymore
5. we make the server side enforce the presence of the 
"Updated-Packages" tag for release branches and packages, just like 
Signed-off-by.

That way, dealing with PKG_RELEASE becomes a matter of simply running 
one command before doing git push.

What do you think?
