build: define RELEASE_YEAR with AC_SUBST
Rather than reading it dynamically from the ChangeLog -- that,
remember, is only a dummy in a Git checkout! To avoid risking
the definition to get out-of-sync, let's enhance the maintainer
target 'update-copyright' to update it automatically (the same
way it's done in the Automake build system).
* configure.ac (RELEASE_YEAR): New AC_SUBST'd variable.
* cfg.mk (update-release-year): New maintainer-specific target
to automatically update the value of that variable.
(update-copyright): Depend on the new target.
* bin/local.mk (RELEASE_YEAR): Drop definition.
(edit): Simplify quoting of $(RELEASE_YEAR).
* lib/Makefile.am (RELEASE_YEAR): Drop definition.
(m4sugar/version.m4): Simplify quoting of $(RELEASE_YEAR).
