[v3] cxxabi.h vs. unwind-cxx.h

In 49818, it's pointed out that none of the EH routines required by
chapter four of the C++ ABI docs are in cxxabi.h. Instead, they are in
unwind-cxx.h. Along with other, GNU-specific implementation items.

Note that the function definitions have always been exported from
the libsupc++/libstdc++ binary. But the declarations have not been in
the required header. 

This conundrum is now fixed with the following patch, which more
cleanly divides the C++ ABI standard from the GNU implementation.
Forward declarations and pointers, solid friends always.
