Log message:
Move the functionality of psignal() to a new function ptsignal()
that takes an additional argument "type" that indicates whether the
signal is for the process, just a particular thread, or propagated
to a thread because it's not caught or blocked.  psignal() becomes
a wrapper that does the first of those.

So that sys_kill() can tell apart signals for the process and signals
for the process's original thread, the tid of the original thread
is defined as its pid + THREAD_PID_OFFSET.
