Commit 6239fe7959 for bind

commit 6239fe7959be60a1833c38cc5fe224c5f9a62462
Author: Michal Nowak <mnowak@isc.org>

    Remove the atomic_ptr() wrapper

    The wrapper has a single user and saves nothing over spelling out
    _Atomic(type *).  Coccinelle cannot parse its definition, so the header
    costs the semantic patches a few lines of coverage for no benefit.

    Assisted-by: Claude:claude-opus-5-5 coccinelle
