Make fputs_unfiltered use fputs_maybe_filtered

This patch redefines fputs_unfiltered in utils.c, with new behavior to
forward parameters to fputs_maybe_filtered.  This makes
fputs_unfiltered identical to fputs_filtered, except filtering is
disabled.

Some callers of fputs_unfiltered have been updated to use ui_file_puts
where they were using other ui_file_* functions anyway for IO.

This fixes the problem I saw with \032\032post-prompt annotation being
flushed to stdout in the wrong order.
