* @brief [LEVEL: beta] the two macros
* @ref DIAGNOSTICS_LOGGING_FACILITY_LOCK_GUARD
* @ref DIAGNOSTICS_LOGGING_FACILITY_LOCK_IS_NESTED
*
* These two macros come in four flavors:
*
* @arg DIAGNOSTICS_INTERNAL_SWITCH_MUTEX == 0 : Null-calls
*
* @arg DIAGNOSTICS_INTERNAL_SWITCH_MUTEX == 3 : Nesting is
* dectectable, but not mutexing happens.
*
* @arg DIAGNOSTICS_INTERNAL_SWITCH_MUTEX == 1 : Nesting is not
* detected, but the calls are mutexed. In particular, nested calls
* will result in a deadlock.
*
* @arg DIAGNOSTICS_INTERNAL_SWITCH_MUTEX == 2 : Nesting is
* dectectable and the calls are mutexed.
*
* @test none
