The rcache functions have been non-public since krb5 1.2.2.  (More
precisely, they were placed inside an #if KRB5_PRIVATE block in 1.2.2,
and removed from krb5.h in 1.4.)

(There is a glaring and ancient inconcistency in that
krb5_get_server_rcache() and krb5_auth_con_getrcache() are public, but
there are no public interfaces to do anything with them, and for
krb5_get_server_rcache() there is no way to free the result.  For the
moment, it's probably best to pretend that they aren't public functions.)
