[boost] current_function.hpp extension

Hi,

I think that some users (me? :) might want to use BOOST_CURRENT_FUNCTION 
only when it contains a meaningful value. Thus, it probably makes sense 
to provide BOOST_HAS_CURRENT_FUNCTION (or should it be called 
BOOST_PROVIDES_CURRENT_FUNCTION?) to reflect this. A possible 
implementation (yeah, pretty easy) is attached, of course the 
documentation should be updated if we agree that the patch makes sense. 
Comments?

Regards, Daniel
