Add guix.scm

The guix.scm file can be used to test the build in various
configurations in a reproducible way.

Once you have guix installed, and up to date, you can use
it with the following command:
$ guix build --file=guix.scm

The filename (guix.scm) is a convention that is also used in
other packages to also do build tests in various configurations.

For more background on the use of guix.scm see the Guix days 2020
presentation about it[1].

+;;; The guix.scm file is a convention: A file named guix.scm is
+;;; found in several project source code, either in the top
+;;; directory or in sub-directories like contrib for instance.
+
+;;; The guix.scm files typically contain package definitions that
+;;; are not meant to be used as regular packages but are meant for
+;;; testing or developing on the given project.
+;;;
+;;; For instance here it is used to build libsamsung-ipc in various
+;;; configurations. Instead distributions would typically be interested
+;;; in only one of the configurations.
+;;;
+;;; It also copies the sources that are present in the directory that
+;;; contains the guix.scm, and builds them. Distributions would instead
+;;; be interested in retrieving the source from git or releases tarballs.
+;;;
+;;; Once you have Guix installed, to build libsamsung-ipc with the
+;;; guix.scm file, you can use the 'guix build --file=guix.scm' command,
+;;; however as explained above, keep in mind that it will copy all the
+;;; files in the same directory than guix.scm, so you might want to
+;;; make sure that the sources are clean (with 'make distclean') if you
+;;; already built libsamsung-ipc in that directory.
+;;;
+;;; While this file could also serve as a basis to make a libsamsung-ipc
+;;; package in Guix, it is probably a good idea to wait until the API
+;;; and ABI changes are complete, ie when the ipc_client has been passed
+;;; to all the exported functions, and make a new release when that is
+;;; done.
