[boost] [type traits] Extension to operator detection -> choose your preferred naming

It is time to include the type trait extension to the official boost trunk.
These traits can detect if you can use a given operator with given arguments.

For example: has_plus<double, int>::value is true because the
following program compiles without error:
double lhs;
int rhs;
lhs+rhs;

We have come to three proposed lists of names (A, B and C):
https://svn.boost.org/trac/boost/wiki/GuideLines/Naming/OperatorTraitNames
I have included the corresponding names of standard keywords, standard
function objects from <functional>, boost Proto and boost Operators.

Please give your preference between A, B and C before Sept. 5th.

Regards,

Frédéric
