In apps/rsa.c, we were second guessing RSA_check_key() to leave error
codes lying around without returning -1 properly.  However, this also
catches other errors that are lying around and that we should not care
about.

It is never valid to call ssl3_read_bytes with
type == SSL3_RT_CHANGE_CIPHER_SPEC, and in fact we check for valid values
for type near the beginning of the function. Therefore this check will never
be true and can be removed.

If a ticket callback changes the HMAC digest to SHA512 the existing
sanity checks are not sufficient and an attacker could perform a DoS
attack with a malformed ticket. Add additional checks based on
