[cp-patches] PATCH: fix PrivateKeyUsagePeriod parsing

[Casey Marshall]

Hi list;

Tom Fitzsimmons pointed out a flaw in the X.509 parsing code that
handles the 'privateKeyUsagePeriod' extension, which is encoded as a
pair of two optional dates, but aren't tagged as such in ASN.1. So the
existing code naively tries to cast the result as a Date, which fails
because the type of the value field can't be determined at that point.

Ok to commit?

        * gnu/java/security/der/DERValue.java
        (getValueAs): new method.
        * gnu/java/security/x509/ext/PrivateKeyUsagePeriod.java
        (<init>): read both dates with 'DERValue.getValueAs', with
        'GENERALIZED_TIME' as the argument.
