[dm-devel] [PATCH 2/3] multipath-tools: add github workflow to save and check ABI

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

This adds a workflow that saves the ABI of libmultipath and the
other libraries, and optionally tests it against a known-good state,
which is taken from the configurable ABI_BRANCH. If the ABI differs,
the workflow fails, and the abidiff output is saved in GH actions
as artifact "abi-test".

To configure the reference branch, set the repository secret ABI_BRANCH to the
name of the branch that contains the ABI reference. The default is "master".
