order to make system diagnostics, tracing and debugging more user
friendly.

Add _TICKET_LOCK_INITIALIZER to statically initialize a
_Ticket_lock_Control structure. This makes it possible to embed a
ticket lock in other structures outside of <sys/lock.h>.

Add _Thread_queue_Queue::_owner which will be used for the upcomming

protocol (OMIP) implementation.

Move _Thread_queue_Queue::_Lock to begin of the structure. On RTEMS,
the presence of a lock component in the thread queue structures actually
depends on the build-time RTEMS_SMP configuration option. A move of
this part to the begin of the structure allows an implementation re-use
for the other parts.

Sorry, there was a typo in <sys/lock.h> which leads to memory corruption
since not enough space is reserved for the lock object.
