[MI non-stop 02/11] Add 'stopped-threads' field to the *stopped output.

[Vladimir Prus <vladimir@codesourcery.com>]

By Pawel' suggestion, the MI non-stop spec say *stopped should explicitly say
which threads are stopped -- so that frontend need not check for 'non-stop'
flag to decide if all threads are stopped or not. It's actually simple to do,
so here's a patch. The infrun.c change affects MI only, so presumably I may
commit it without seeking approval?

- Volodya

	[gdb]
	* infrun.c (normal_stop): For MI, report which threads
	were stopped.

	[gdb/testsuite]
	* lib/mi-support.exp (mi_expect_stop): Adjust for the new field.
