Move certificate verification off the IO thread.

Move the MapNetErrorToCertStatus and MapCertStatusToNetError
functions to cert_status_flags.h so they can be shared with
Mac and Linux code.

Move the certificate verification function to the
X509Certificate class.  Right now X509Certificate::Verify is
only implemented on Windows.
