Use a script to update DEBUG macro invocations to use it as a variadic
macro, supplying format string and its arguments directly, instead of
wrapping them in parens.

This script was used to update the code:

grep -rwl --include '*.[hc]' DEBUG . |
    while read f; do
        mv "$f"{,.orig}
        perl -e \
            'use strict;
             use File::Slurp;
             my $text=read_file(\*STDIN);
             $text=~s#(\bDEBUG\s*\([^(]+)\((.*?)\)\s*\)\s*;#$1$2);#gs;
             print $text;' < "$f.orig" > "$f"
        rm "$f.orig"
    done

PAC, SSH, SUDO and AUTOFS services' debug levels weren't modified when
sss_debuglevel tool was used.

Use this function instead of explicitly calling domain->next

This function allows to get the next primary domain or to descend into the
subdomains and replaces also get_next_dom_or_subdom()
