BACKENDS: Implement logging API proposed by Max on -devel.

This commits a slightly modified patch from my patch tracker item #3104630
"OSYSTEM: Add logging API as proposed by Max on -devel".

I was not able to test compilation on Android and SamsungTV, since there is no
toolchain for those on buildbot (or I was too blind to find them).
