  /** Determines the validity of a certificate chain, outside the context
   * of a TLS session.
   * 
   *  @a chain is a chain of TlsCertificate objects each pointing to the next
   * certificate in the chain by its TlsCertificate::property_issuer() property.
   * 
   *  @a purpose describes the purpose (or usage) for which the certificate
   * is being used. Typically @a purpose will be set to G_TLS_DATABASE_PURPOSE_AUTHENTICATE_SERVER
   * which means that the certificate is being used to authenticate a server
   * (and we are acting as the client).
   * 
   * The @a identity is used to ensure the server certificate is valid for
   * the expected peer identity. If the identity does not match the
   * certificate, Gio::TlsCertificateFlags::BAD_IDENTITY will be set in the
   * return value. If @a identity is <tt>nullptr</tt>, that bit will never be set in
   * the return value. The peer identity may also be used to check for
   * pinned certificates (trust exceptions) in the database. These may
   * override the normal verification process on a host-by-host basis.
   * 
   * Currently there are no @a flags, and Gio::TlsDatabaseVerifyFlags::NONE should be
   * used.
   * 
   * If @a chain is found to be valid, then the return value will be 0. If
   *  @a chain is found to be invalid, then the return value will indicate at
   * least one problem found. If the function is unable to determine
   * whether @a chain is valid (for example, because @a cancellable is
   * triggered before it completes) then the return value will be
   * Gio::TlsCertificateFlags::GENERIC_ERROR and @a error will be set accordingly.
   *  @a error is not set when @a chain is successfully analyzed but found to
   * be invalid.
   * 
   * GLib guarantees that if certificate verification fails, at least one
   * error will be set in the return value, but it does not guarantee
   * that all possible errors will be set. Accordingly, you may not safely
   * decide to ignore any particular type of error. For example, it would
   * be incorrect to mask Gio::TlsCertificateFlags::EXPIRED if you want to allow
   * expired certificates, because this could potentially be the only
   * error flag set even if other problems exist with the certificate.
   * 
   * Prior to GLib 2.48, GLib's default TLS backend modified @a chain to
   * represent the certification path built by TlsDatabase during
   * certificate verification by adjusting the TlsCertificate::property_issuer()
   * property of each certificate in @a chain. Since GLib 2.48, this no
   * longer occurs, so you cannot rely on TlsCertificate::property_issuer() to
   * represent the actual certification path used during certificate
   * verification.
   * 
   * Because TLS session context is not used, TlsDatabase may not
   * perform as many checks on the certificates as TlsConnection would.
   * For example, certificate constraints may not be honored, and
   * revocation checks may not be performed. The best way to verify TLS
   * certificates used by a TLS connection is to let TlsConnection
   * handle the verification.
   * 
   * The TLS backend may attempt to look up and add missing certificates
   * to the chain. This may involve HTTP requests to download missing
   * certificates.
   * 
   * This function can block. Use g_tls_database_verify_chain_async() to
   * perform the verification operation asynchronously.
