[PATCH] Fix =thread-created not showing up when detaching

[Simon Marchi <simon dot marchi at ericsson dot com>]

Hi,

This patch refers to this bug, reported a few days ago:

http://sourceware.org/bugzilla/show_bug.cgi?id=15564

Since the behavior was different between native and remote debugging, I 
wasn't sure which was right. After 2-3 seconds of reflexion, I believe 
that the =thread-exited event is relevant in this case. IIUC, we must 
think of thread-created as "GDB learns about a thread", whether is has 
really just been created or not (in case of attach), and thread-exited 
as "GDB forgets about a thread", whether it has really exited or not (in 
case of detach).

With this patch, =thread-exited now appears when detaching. I didn't see 
any side effects (but your more trained eye might). There is no change 
in existing tests results. I would be happy to add a test for this, but 
I am unsure where it belongs, any suggestions are appreciated!

Thanks,

Simon
