Taking function objects by value instead of as references-to-const. This does not work on MSVC6.5, so the BOOST_MSVC_ONLY macro was added to make them references-to-const for only that compiler.

- Borland C++ no longer requires hacks to make function pointers work
- On any compiler other than MSVC, free functions can be assigned to Boost.Function objects without the explicit '&'
