ssl-proxies: Fix CRL refresh bug

The CertifcationRevocationList class caches CRL information to
reduce the cost of reloading them too often.

The caching logic contains a bug in which any call to the refresh
method will update the timestamp for the last reload even when
CRLs have not been reloaded. The consequence is that if refresh is
called sufficiently often, the CRLs will never be reloaded.
ssl-proxies: Fix CRL check race condition

JGlobus uses CRLs as if they were immutable objects, however when
using the Bouncy Castle provider, the ASN.1 parser uses lazy
evaluation internally, which means the X509CRL object is not
thread safe.
