Change code that either called error() and proceeded to exit with 128,
or emitted its own "fatal: " messages to use the die_message()
function added in a preceding commit.
In order to do that we need to add a get_die_message_routine()
function, which works like the other get_*_routine() functions in
usage.c. There is no set_die_message_rotine(), as it hasn't been
needed yet. We can add it if we ever need it.
