create_module.2, delete_module.2, init_module.2, query_module.2: Clarify glibc header file declaration/ABI wrapper details
create_module(), delete_module(), init_module(), and
query_module() are not declared in header files, but
through an accident of history glibc provides an ABI
for them that it continues to maintain, for
compatibility reasons.
