Draft: Add Provides: based ABI versioning mechanism
For discussion. See debian-devel@ thread for details.
Some hardware presents an ABI to userspace that varies depending on the firmware version used. To avoid breaking depending packages, binary packages from firmware-nonfree can now declare virtual ABI packages with versioned Provides: for depending packages to use with automatic management inside the packaging to ensure that ABI versions are bumped when their underlying firmware files change.
See debian/README.source for details.
