* \brief Requests execution of provided function in the specified thread.
*
* Main use case for this function is to request execution of signals delivery function. In such case it is called when
* an unblocked signal, which is not ignored, is generated or queued for specified thread.
*
* It must arrange for given function to be executed in specified thread as soon as possible. This generally requires
* dealing with following scenarios:
* - current thread is sending the request to itself - in that case just execute function right away;
* - current thread is sending the request to non-current thread;
* - interrupt is sending the request to current thread;
* - interrupt is sending the request to non-current thread;
*
* \param [in] threadControlBlock is a reference to internal::ThreadControlBlock of thread in which \a function should
* be executed
* \param [in] function is a reference to function that should be executed in thread associated with
* \a threadControlBlock
