As before: why using a signed integer?

As before: I use integer because another timer ( e.g. next_flush_time_ ) use integer, too.

This patch is for the performance issue : #753.
Originally, "LogCleaner" scanned all the log directories every time we flush. In the common case, we flush every 30 seconds and then called "LogCleaner::Run". But if we flush every time we do "LogFileObject::Write" like the test code from @kimi20071025, we'll call "LogCleaner::Run" so many times.
In this patch, I maintain an additional timer
next_cleanup_time_( thank @aesophor for the advice ), and avoid scanning the logs too frequently.
