62515: When a connector is configured (via setting bindOnInit to false) to bind/unbind the server socket during start/stop, close the socket earlier in the stop process so new connections do not sit in the TCP backlog during the shutdown process only to be dropped as stop completes.

60087: Refactor the web resources handling to use the Tomcat specific war:file:... URL protocol to refer to WAR files and their contents rather than the standard jar:file:... form since some components of the JRE, such as JAR verification, give unexpected results when the standard form is used.
