[PATCH] Print thread name in thread apply headers

[PATCH] Print thread name in thread apply headers

[Dr. David Alan Gilbert]

The thread name is currently shown in 'info thread' but not in
thread apply.  Adding it to thread apply makes it easier to figure out
what's happening in backtraces of multithreaded programs gathered with
a  'thread apply all bt full'.

gdb/ChangeLog:

	* thread.c: Add thread name to thread apply headers.
