Merged r1593877 from tomcat/trunk:
- ThreadLocalLeakPreventionListener: Trigger thread renewals for StandardContext only. (Do not trigger them for FailedContext and similar).
- StandardThreadExecutor: Pass 'threadRenewalDelay' to the thread pool executor. Otherwise this setting configured at initialization time is effectively ignored.
- Improve documentation.
