Increments the external-modification statistics recording a task_for_pid on the target task: bumps the caller's task_for_pid_caller_count, the target's task_for_pid_count, and the host-wide count. Does nothing when the caller is the kernel task, when target is TASK_NULL, or when a task acts on itself. These counters (task_extmod_info, host statistics) help triage crashes caused by one userspace task modifying another.

Increments the external-modification statistics recording a thread_set_state on a thread of another task: bumps the caller's thread_set_state_caller_count, the target task's thread_set_state_count, and the host-wide count. Does nothing when the caller is the kernel task, target is THREAD_NULL, or the thread belongs to the calling task.

Increments the external-modification statistics recording creation of a thread in another task: bumps the caller's thread_creation_caller_count, the target's thread_creation_count and the host-wide count, and logs the event to the BSD message tracer. Does nothing when the caller is the kernel task, target is TASK_NULL, or a task creates a thread in itself.
