/**
* @brief Generic interface for semaphores, which can be used to achieve

* used for both binary semaphores and counting semaphores.
* @details
* A semaphore is a synchronization primitive.
* See: https://en.wikipedia.org/wiki/Semaphore_(programming)
* A semaphore can be used to achieve task synchonization and track the
* availability of resources by using either the binary or the counting
* semaphore types.
*
* If mutual exlcusion of a resource is desired, a mutex should be used,
* which is a special form of a semaphore and has an own interface.
