 *
 * Macro which should be defined as one of:

 * - TRACE_STORE_MODE_STOP_WHEN_FULL
 * Default is TRACE_STORE_MODE_RING_BUFFER.
 *
 * With TRACE_RECORDER_STORE_MODE set to TRACE_STORE_MODE_RING_BUFFER, the events are
 * stored in a ring buffer, i.e., where the oldest events are overwritten when
 * the buffer becomes full. This allows you to get the last events leading up
 * to an interesting state, e.g., an error, without having a large trace buffer
 * for string the whole run since startup. In this mode, the recorder can run
 * "forever" as the buffer never gets full, i.e., in the sense that it always
 * has room for more events.
 *
 * To fetch the trace in mode TRACE_STORE_MODE_RING_BUFFER, you need to first halt the
 * system using your debugger and then do a RAM dump, or to explicitly stop the
 * recorder using vTraceStop() and then store/upload the trace data using a
 * task that you need to provide yourself. The trace data is found in the struct
 * RecorderData, initialized in trcBase.c.
 *
 * Note that, if you upload the trace using a RAM dump, i.e., when the system is
 * halted on a breakpoint or by a debugger command, there is no need to stop the
 * recorder first.
 *
 * When TRACE_RECORDER_STORE_MODE is TRACE_STORE_MODE_STOP_WHEN_FULL, the recording is
 * stopped when the buffer becomes full. When the recorder stops itself this way
 * vTracePortEnd() is called which allows for custom actions, such as triggering
 * a task that stores the trace buffer, i.e., in case taking a RAM dump
 * using an on-chip debugger is not possible. In the Windows port, vTracePortEnd
 * saves the trace to file directly, but this is not recommended in a real-time
 * system since the scheduler is blocked during the processing of vTracePortEnd.

 *
 * ### Instance Finish Events (IFE) ###
 *
 * For tasks with "infinite" main loops (non-terminating tasks), the concept
 * of a task instance has no clear definition, it is an application-specific
 * thing. Tracealyzer allows you to define Instance Finish Events (IFEs),
 * which marks the point in a cyclic task when the "task instance" ends.
 * The IFE is a blocking kernel call, typically in the main loop of a task
 * which typically reads a message queue, waits for a semaphore or performs
 * an explicit delay.
 *
 * If USE_IMPLICIT_IFE_RULES is one (1), the kernel macros (trcKernelPort.h)
 * will define what kernel calls are considered by default to be IFEs.
 *
 * However, Implicit IFEs only applies to blocking kernel calls. If a
 * service reads a message without blocking, it does not create a new
 * instance since no blocking occurred.
 *
 * Moreover, the actual IFE might sometimes be another blocking call. We
 * therefore allow for user-defined Explicit IFEs by calling
 *
 *     vTraceTaskInstanceIsFinished()
 *
 * right before the kernel call considered as IFE. This does not create an
 * additional event but instead stores the service code and object handle
 * of the IFE call as properties of the task.
 *
 * If using Explicit IFEs and the task also calls an Implicit IFE, this may
 * result in additional incorrect task instances.
 * This is solved by disabling the Implicit IFEs for the task, by adding
 * a call to
 *
 *     vTraceTaskSkipDefaultInstanceFinishedEvents()
 *
 * in the very beginning of that task. This allows you to combine Explicit IFEs
 * for some tasks with Implicit IFEs for the rest of the tasks, if
 * USE_IMPLICIT_IFE_RULES is 1.
 *
 * By setting USE_IMPLICIT_IFE_RULES to zero (0), the implicit IFEs are disabled
 * for all tasks. Tasks will then be considered to have a single instance only,
 * covering all execution fragments, unless you define an explicit IFE in each
 * task by calling vTraceTaskInstanceIsFinished before the blocking call.
