The thread driver for P8 and P9 maintains the current state of
hardware thread.  This is used to make decisions on whether you can
stop/start/reset a thread or execute instructions on a thread.

The sbefifo thread driver did not implement thread status.  These patches add
state() hardware procedure to thread to correctly implement obtaining the
thread status of hardware thread.  Currently only P9 threads are supported
with sbefifo thread driver, so p9_thread_state() is used to calculate the
thread state in sbefifo thread implementation.

Amitay Isaacs (8):
  libpdbg: Rename get_thread_status to p8_thread_state
  libpdbg: Rename p9_get_thread_status to p9_thread_state
  libpdbg: Add state() method to thread
  libpdbg: Use thread method to get state
  libpdbg: Expose p9_thread_state method
  libpdbg: Implement state method for sbefifo thread
  libpdbg: Update thread status when starting/stopping a thread
  libpdbg: Update thread state when starting/stopping all threads
