Merge branch 'ab/unused-annotation'

Undoes 'jk/unused-annotation' topic and redoes it to work around
Coccinelle rules misfiring false positives in unrelated codepaths.

* ab/unused-annotation:
  git-compat-util.h: use "deprecated" for UNUSED variables
  git-compat-util.h: use "UNUSED", not "UNUSED(var)"
