Support Reporting Running State and Alive Notifications for applications written in C

[NicolasFussberger]

Previously, we removed the C-prototypes as they were not necessary for C++/rust interaction (rust code has their own function prototypes).

However, this also removed the support for applications written in C, which we otherwise get for free.

This PR adds back the function prototypes and adds an example application written in C that invokes the functions for reporting Running state and Alive Notifications.
