[RFC PATCH 17/21] usage.c: move usage routines around

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

A move-only change to re-order the usage routines in the order of
usage,die,die_message,error,warning, and to have the "errno" variant
after the non-errno variant, in addition to defining them all after
the fmt_with_err() helper which some of them need.

This change make a subsequent non-refactoring commit's diff smaller.
