Make sure ChangeLog is built by make
* Makefile.am: Mark ChangeLog as noinst_DATA to trigger its rule. Rewrite the ChangeLog rule using a wrapper over gitlog-to-changelog, which rewrites the file only when needed. (dist-hook): Fail if there are uncommitted changes. * mu-aux/gencl: New file. * maint.mk: Remove.
