Hi all,
Could you review this fix that moves the cleanup of dead entries in the 
protection domain table from the VMThread to the ServiceThread.
The goal is the same as JDK-8206423. The task of cleaning up dead 
entries in the protection domain table was moved to the ServiceThread.
The fix was tested with Mach5 on tiers 1, 2, 3 on all platforms. A new 
test (test/hotspot/jtreg/runtime/appcds/CleanProtectionDomain.java) was 
added to test the creation and removal of entries in the Protection 
Domain table.
