gdb/testsuite/
	Fix ERROR: internal buffer is full.
	* gdb.base/info-os.exp (expect_multiline): New function.
	(get process list, get process groups, get threads)
	(get file descriptors, get internet-domain sockets)
	(get shared-memory regions, get semaphores, get message queues): Use
	it for these tests.
