[PATCH]: Update thread list

[Michael Snyder <msnyder at cygnus dot com>]

I can think of two times when it is both safe and useful 
for GDB to go query the target to find out if there are 
any new threads.
 1) "info threads" and
 2) "thread apply all xxx"

This change adds the second (the first is already in place).

        * thread.c (thread_apply_all_command): Update thread list first.
