src: replace NULL with nullptr

Now that we are building with C++11 features enabled, replace use
of NULL with nullptr.

The benefit of using nullptr is that it can never be confused for
an integral type because it does not support implicit conversions
to integral types except boolean - unlike NULL, which is defined
as a literal `0`.
