Fix CVE-2020-11945: An issue was discovered in Squid before 5.0.2. A
remote attacker can replay a sniffed Digest Authentication nonce to gain
access to resources that are otherwise forbidden. This occurs because
the attacker can overflow the nonce reference counter (a short integer).
Remote code execution may occur if the pooled token credentials are
freed (instead of replayed as valid credentials).
