Tweak the in-kernel API for sending signals to threads:

- Rename tdsignal() to tdsendsignal() and make it private to kern_sig.c.
- Add tdsignal() and tdksignal() routines that mirror psignal() and
  pksignal() except that they accept a thread as an argument instead of
  a process.  They send a signal to a specific thread rather than to an
  individual process.
