Since this is
a public API I don't know if the old function can be removed.
I thought public api is in auth_comp128* e. g. osmo_auth_gen_vec() -
see tests/comp128_test.c for usage examples. And functions like
comp128v*() are internal implementation details.
Using osmo_auth_*() is the recommended API but comp128v*() are also
in the installed header files and thus also part of the public API.
