[RFC] Switching to SPDX in license tags

[Haïkel]

Hi,

I would like to get feedback from Fedora Legal and also my fellow
contributors about considering
SPDX.

SPDX (Software Package Data Exchange) is a specification hosted by the
Linux Foundation defining
a standard format for communicating components, licenses and
copyrights associated with a software package.
https://spdx.org/

It would make it much easier collaborating with other distributions
and upstream projects.

On a more practical side, it would mean standardizing on SPDX short
identifier to design licenses
and exceptions in all our packages.

Your feedback?

Regards,
H.
