bedf208cbd Use fmt::runtime() for LOG_* for non constexpr 
Here is oneliner:

    $ gg 'LOG_\(DEBUG\|TRACE\|INFO\|TEST\|WARNING\|ERROR\|FATAL\)([^,]*, [a-zA-Z]' -- :*.cpp :*.h | cut -d: -f1 | sort -u | xargs -r sed -E -i 's#(LOG_[A-Z]*)\(([^,]*), ([A-Za-z][^,)]*)#\1(\2, fmt::runtime(\3)#'

Note, that I tried to do this with coccinelle (tool for semantic
patchin), but it cannot parse C++:

    $ cat fmt.cocci
    @@
    expression log;
    expression var;
    @@

    -LOG_DEBUG(log, var)
    +LOG_DEBUG(log, fmt::runtime(var))

I've also tried to use some macros/templates magic to do this implicitly
in logger_useful.h, but I failed to do so, and apparently it is not
possible for now.
