[PATCH phosphor-event] Event Logs to survive a reboot

[OpenBMC Patches]

The event service stores the events from the host.  Before this commit all the code was in memory.  That meant once a reboot occured you lost the logs.  With this commit I am storing all logs to the file system.  This refactoring also enables a test suite.  The suite can be invoked by 'make test; ./test'.

1) /var/sys/obmc/events/x
2) logs are stored in binary and saved
3) Each log now has a timestamp of when the log reached the service
4) I added a caching mechanism to reduce the io traffic if the the method is simply being called to capture the next parameter
5) You will notice a mixture of c/c++.  This is because I want the test infrastructure to take advantage of c++ features
