[boost] [shifted_ptr] Now supports <void>, multithread roots & preprocessor code

Greetings:

Ok, this a nice feature that just got added to the pointer.  I just added 
support for "void" pointers and works perfectly.  We can see the object 
being deleted correctly after the shifted_ptr<void> is destructed.

Furthermore a very nice property shifted_ptr_base has is that it can be 
casted to a regular pointer and back again to a shifted_ptr_base and the 
pointee will still be correctly deallocated.  I never saw any production 
code using perfect C++ coding and sometimes it happens we rely on "working 
undefined behaviors".

Multithreaded support has been added but unfortunately I didn't see any 
function returning the current thread id.  Was this disregarded?

Finally I am using cleaner preprocessor coding for variadic function 
templates:
