Use vnode interlock to protect the knote fields. The locking assumes that shared vnode lock is held, thus we get exclusive access to knote either by exclusive vnode lock protection, or by shared vnode lock + vnode interlock. Unlike the change in HEAD, this does not remove kl_locked() and replace it with kl_assert_locked() and kl_assert_unlocked(). Instead, the kl_locked can now be set to NULL in which case no assertion checks are performed on the lock. The vfs kqfilter code uses this mode to disable assertion checks. This preserves the existing ABI for knlist_init(). Add convenience function knlist_init_mtx to reduce number of arguments for typical knlist initialization.

Test this flag instead of td_ar when auditing syscall arguments or checking for an audit record to commit on syscall return. Under these circumstances, td_pflags is much more likely to be in the cache (especially if there is no auditing of the current system call), so this should help reduce cache misses in the system call return path.
