233: code review changes to lifecycle event adapter

- this file's contents were not yet be used anywhere. As such, I feel that it will need more extensive review once it is actually put into play. It this file was not included in the build (Makefile) so I added it in order to locate and fix any warnings. I also did do extensive preliminary review of the code.
- renamed the eventadapter file to match the class it defines. In most cases we don't want to be defining multiple classes in a single file.
