Call krb5_free_principal() to free princ when it is no longer needed.

Beginning with release 1.20, the name type of the principal will be inferred as KRB5_NT_SRV_INST or KRB5_NT_WELLKNOWN based on the principal name. The type will be KRB5_NT_PRINCIPAL if a type cannot be inferred.


krb5_build_principal() and krb5_build_principal_alloc_va() perform the same task. krb5_build_principal() takes variadic arguments. krb5_build_principal_alloc_va() takes a pre-computed varargs pointer.
