Add supported for X509ExtendedTrustManager when using OpenSslEngine

Browse Source 
Motivation:

For some use cases X509ExtendedTrustManager is needed as it allows to also access the SslEngine during validation.

Modifications:

Add support for X509ExtendedTrustManager on java >= 7

Result:

It's now possible to use X509ExtendedTrustManager with OpenSslEngine
