Bartosz Golaszewski 76ecc337c5 licensing: relicense C++ bindings under LGPL-2.1-or-later
Commit ea84f882d5 ("licensing: relicense C++ library code under
LGPL-3.0-or-later") changed the license of C++ bindings in order to
solve potential issues with code generated from templates[1], default
implementations, etc. However this change makes the bindings less
attractive to projects that have strict licensing restrictions and avoid
GPL-3.0 code[2].

After talking to Grant Likely I decided that the best approach is to
make the bindings available under LGPL-v2.1-or-later and simply let the
end user decide which version's text to apply.

While at it: tweak the README to also mention that examples are provided
under GPL-2.0-or-later.
