JDK-8285240: HTTPS Channel Binding support for Java GSS/Kerberos

Support has been added for TLS channel binding tokens for Negotiate/Kerberos authentication over HTTPS through javax.net.HttpsURLConnection.

Channel binding tokens are increasingly required as an enhanced form of security which can mitigate certain kinds of socially engineered, man in the middle (MITM) attacks. They work by communicating from a client to a server the client's understanding of the binding between connection security (as represented by a TLS server cert) and higher level authentication credentials (such as a username and password). The server can then detect if the client has been fooled by a MITM and shutdown the session/connection.

The feature is controlled through a new system property jdk.https.negotiate.cbt which is described fully at the following page: https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/net/doc-files/net-properties.html#jdk.https.negotiate.cbt

JDK-8278386: Default JDK compressor will be closed when IOException is encountered

DeflaterOutputStream.close() and GZIPOutputStream.finish() methods have been modified to close out the associated default JDK compressor before propagating a Throwable up the stack. ZIPOutputStream.closeEntry() method has been modified to close out the associated default JDK compressor before propagating an IOException, not of type ZipException, up the stack.
