LGPL-2.1 is a license meant for shared libraries. Because I didn't know
any better I used it for all files in the repository, including programs
linking against libgpiod. The standard approach for many similar projects
is to use LGPL for library code and GPL for programs (and also Makefiles
and other files containing code or configuration).
Relicense all programs, tests, makefiles and autotools files under
GPL-2.0 or later.

In order to make the licensing situation of libgpiod clear and enable
easy reusing of the code, let's make all the files in the repository
compliant with the REUSE v3.0 specification.
In order to achieve that:
- put all used licenses into a separate LICENSES/ directory
- add SPDX license identifiers to all files that were missing them with
regular text files being licensed under CC-BY-SA-4.0, while files
containing code and configuration are licensed under GPL-2.0-or-later
- replace custom copyright texts with SPDX-FileCopyrightText
- update the gpio.h kernel uAPI header with the upstream version where
the SDPX license identifier was fixed to use 'GPL-2.0-only' variant
instead of the deprecated 'GPL-2.0'

Use the SPDX license identifier for LGPLv2.1 or later in the public
API header and the corresponding Makefile.am.

This project contains both a library and executables so it's better to
use an umbrella term "This program ..." than "This library ..." in all
the source files.

The license type of COPYING file is "LGPL-2.1+", but it is declared
as "LGPL-2.1" in the preamble of source files.
This patch fixes license type inconsistency issue in each source file.

The library is much less useful under GPLv3 - change the license
to the more permissive LGPLv2.1 for the entire project.
