Fix krb5_copy_context

krb5_copy_context has been broken since 1.8 (it broke in r22456)
because k5_copy_etypes crashes on null enctype lists.  Subsequent
additions to the context structure were not reflected in
krb5_copy_context, creating double-free bugs.  Make k5_copy_etypes
handle null input and account for all new fields in krb5_copy_context.
Reported by Arran Cudbard-Bell.
