e04c319d21 Added new default certificate callbacks with extended information. 
The extended information provided by VerifyCertificateEx and
VerifyChangedCertificateEx is now exploited by the new functions
client_cli_verify_certificate_ex and client_cli_verify_changed_certificate_ex.

The old callbacks now print out deprecation warnings to inform the
user and developer about this deprecation.
