auth: improve the mig mutator functions

Previously, the mig mutator function auth_port_to_handle was defined
in auth.c (fakeauth.c), preventing it from being inlined into the
mig-generated server functions.  Put it in mig-decls.h instead.
Rename authmutations.h to mig-mutate.h, auth_mig.h to mig-decls.h.
This is the naming convention used for pflocal.

* auth/auth.h: New file.
* auth/auth_mig.h: Rename to mig-decls.h, add copyright notice, define
mutator functions.
* auth/authmutations.h: Rename to mig-mutate.h, restore copyright
notice, adjust accordingly.
* auth/auth.c: Include auth.h, remove auth_port_to_handle.
* utils/fakeauth.c: Likewise.
* auth/Makefile: Adjust accordingly.
* utils/Makefile: Likewise.
