semi-manual remove of not used #define commands

As i was upset to see all these #define with no code under, i made a
global pass to remove the obvious cases semi-manual remove of not used
bodies

manual script, then a lot of manual review

    grep -IRs "#define" ../openair* ../common/* ../executables/ ../nfapi/ ../radio/ | \
        fgrep -v '(' | fgrep -v '//' |awk '{print $2}' | egrep -v "#define *$n"| \
            while read n ; do
              grep -IRs $n ../openair* ../common/* ../executables/ ../nfapi/ ../radio/  | grep -v "#define *$n" | grep -q $n || echo $n;
            done

will give a decent list of #define never used.  Then, I think we should
keep lists of # define when it comes from standards, even if the code
doesn't use it right now
