wrap_unsafe_function
declares a function wrapper to a function that
causes an R CMD check
NOTE when called directly. We should usually
not call these functions, but we need some of them because we want to
explicitly support features they provide.
wrap_unsafe_function(ns, name)
wrap_unsafe_calls
returns a wrapper function with the same
argument as the wrapped function that can be called without causing a NOTE.
The namespace of the unsafe function.
The name of the unsafe function.
