#4720: [function][patch] function wrapper with no exception safety guarantee

Milestone:  To Be Determined  |   Component:  function

------------------------------+---------------------------------------------
 boost::function provides a strong exception safety guarantee. However, in
 certain circumstances, such as some embedded systems, no exception safety
 guarantee is desirable. I request that function object wrappers with no
 exception safety guarantee be added to the Boost.Function family. The
 attached patch implements boost::unsafe_function (with both preferred
 syntax and portable syntax), which has no exception safety guarantee when
 invoked with no target and has no dependency on boost::throw_exception.
 The patch includes tests and documentation updates. It addresses the same
 issue identified in #4646.
