From fc23a9bd5012d07cc6ef9d1eba12f320763068d9 Mon Sep 17 00:00:00 2001

Subject: Add support for package base co-maintainers

This allows for having multiple co-maintainers for AUR packages.
Co-maintainers have push access to the package base Git repository but
are not allowed to change the package base category, disown the package
or modify the list of co-maintainers. The primary maintainer of an AUR
package can edit the list of co-maintainers from the Package Actions
box.

Implements FS#17911.
