Hello Markus,

we have not looked at CRL reloading lately so I can not tell if the new
functions would help with CRL reloading. However, a quick look at
OpenSSL shows the CRL lookups in X509_STORE_add_crl are done differently
in 1.x versions than e.g., in 0.9.8x. Also, these changes between 0.9.x
and 1.0.0 look promising (OpenSSL changelog):

  *) Allow multiple CRLs to exist in an X509_STORE with matching issuer
names.
     Modify get_crl() to find a valid (unexpired) CRL if possible.
     [Steve Henson]

  *) New function X509_CRL_match() to check if two CRLs are identical.
Normally
     this would be called X509_CRL_cmp() but that name is already used by
     a function that just compares CRL issuer names. Cache several CRL
     extensions in X509_CRL structure and cache CRLDP in X509.
     [Steve Henson]

If you plan to test this, can you see if you get different results with
OpenSSL 1.0.x versions than 0.9.8x?

Thanks,
Heikki
