Declare copyright and licensing using REUSE
To fill in some gaps, I've had to make some assumptions:
- trivial changes (such as checking for an additional function or header file in libglnx.m4) are assumed to not be copyrightable
- Will Thompson and Matthew Leeds are assumed to be contributing on
behalf of
Endless Mobile Inc.Endless OS Foundation - files with no explicit licensing information are assumed to be under the license found in COPYING
