Date:           Tue Mar  4 00:40:42 UTC 2025

Modified Files:
        src/common/lib/libc/atomic: atomic_op_namespace.h

Log Message:
libc atomic_op_namespace.h: Add membar_release and membar_acquire.

These namespace macros will be needed so that libpthread can call
NetBSD's nonstandard membar_release/acquire functions even if linked
against an application that defines symbols of the same name.

Preparation for:

PR lib/59126: pthread_once(3): missing memory ordering
