MINOR: threads: add a "stuck" flag to the thread_info struct

This flag is constantly cleared by the scheduler and will be set by the
watchdog timer to detect stuck threads. It is also set by the "show
threads" command so that it is easy to spot if the situation has evolved
between two subsequent calls : if the first "show threads" shows no stuck
thread and the second one shows such a stuck thread, it indicates that
this thread didn't manage to make any forward progress since the previous
call, which is extremely suspicious.
