Bug 1288870, part 1 - Add NS_INLINE_DECL_REFCOUNTING_WITH_DESTROY. r=froydnj

Browse Source 
This is the same basic idea as NS_IMPL_RELEASE_WITH_DESTROY. I need
this because I am making XPCNativeInterface refcounted, and it uses
some weird placement new stuff requiring a special function to
deallocate the object. (It does this to store an array of arbitrary
length inline, presumably for some sort of time or space reason.)
