Konstantin Belousov b631c36f0d Record part of the owner struct thread pointer into busy_lock. ... Record as much bits from curthread into busy_lock as fits. Low bits for struct thread * representation are zero due to struct and zone alignment, and they leave space for busy flags (perhaps except statically allocated thread0). Upper bits are not very interesting for assert, and in most practical situations recorded value should allow to manually identify the owner with certainity. Assert that unbusy is performed by the owner, except few places where unbusy is done in io completion handler. For this case, add _unchecked variants of asserts and unbusy primitives.
