ECLServerHandler.java:
Many small changes to improve the readability of this code:
Renamed getOldestChangeFromDomainCtxts() to findOldestChangeFromDomainCtxts() and return the actual DomainContext object instead of its index.
Extracted methods initializeChangelogSearch() and hasCookieBeenTrimmedFromDB().
Renamed initializeCLDomCtxts() to initializeChangelogDomainCtxts().
Reduced variable scopes.
