description:
Kill SA thread states (TD_STATE_*) in pthread_dbg and add TD_STATE_DEAD

Scheduler Activation types were removed in NetBSD 5.0. Old type set is not
matching the new world POSIX threads library.

Only TD_STATE_RUNNING, TD_STATE_ZOMBIE are still applicable - keep it.

Keep TD_STATE_UNKNOWN as generic unrecognized type.

Add new TD_STATE_DEAD one. The TD_STATE_DEAD type is represented by number
6 in the POSIX threads library, but for the sake of compatibility with
older software using pthread_dbg - renumber it to 7, as six was reserved
for TD_STATE_SUSPENDED.

Old removed state types are marked as reserved and unused.
