Replace individual license references with SPDX Identifiers

This patch replaces license headers with SPDX identifiers in all files
containing license headers.  For each file, the SPDX identifier
formally represents its current license.  Note that the list of SPDX
identifiers is available on the SPDX web site at
https://spdx.org/licenses.

For autoconf-archive/ax_prog_python_version.m4 however, there is a
little catch.  Dodji Seketeli wrote this ax_check_python_modules.m4.
Just like the other autoconf-archive macros, it makes sense to have it
under the FSF All Permissive license.  Actually, the terms of that
license was already in the file but then the license header was
wrongly set to GPLv2 with autoconf exception.  So I fixed that in this
commit by setting the SPDX identifier to FSFAP.
