[PATCH] kdtree.hpp: qualify base class calls

[Max Kellermann]

kdtree.hpp does not compile with LLVM's clang++ compiler, because it
violates the C++ standard, resulting in the error message:

 "must qualify identifier to find this declaration in dependent base
 class"

This is best explained on the clang home page:

 http://clang.llvm.org/cxx_compatibility.html

"When we look up a name used in a class, we usually look into the base
classes. However, we can't look into the base class Base<T> because
its type depends on the template argument T, so the standard says we
should just ignore it."
