57c1b3eda6 system: handle invalid enablement in String method
Invalid enablement is only caused by bad API usage, however panicking on the spot leaves behind messy state that has to be manually cleaned up.

5401882ed0 init: post initial process death exit timeout
Wait for 5 seconds before printing a message and exiting after picking up the initial process's wait status. This also kills any lingering processes.This behaviour is helpful for applications launched without a terminal attached.

084cd84f36 app: port app to use the system package
This commit does away with almost all baggage left over from the Ego port. Error wrapping also got simplified. All API changes happens to be internal which means no changes to main except renaming of the BaseError type.
