This function is called whenever the initialization function
of a real object is called.
</p><p>
When the real object is already tracked by debugobjects it is
checked, whether the object can be initialized. Initializing
is not allowed for active and destroyed objects. When
debugobjects detects an error, then it calls the fixup_init
function of the object type description structure if provided
by the caller. The fixup function can correct the problem
before the real initialization of the object happens. E.g. it
can deactivate an active object in order to prevent damage to
the subsystem.
</p><p>
When the real object is not yet tracked by debugobjects,
debugobjects allocates a tracker object for the real object
and sets the tracker object state to ODEBUG_STATE_INIT. It
verifies that the object is not on the callers stack. If it is
on the callers stack then a limited number of warnings
including a full stack trace is printk'ed. The calling code
must use debug_object_init_on_stack() and remove the object
before leaving the function which allocated it. See next
section.
