Make cached executor service use linked blocking queue

Browse source 
Since e6045c6593 the cached executor
services maximum pool size is limited to concurrencyLevel (was
previously Integer.MAX_VALUE). In order to prevent
RejectExecutionException we need to use an queue which max size is
greater than 1 (i.e. nont an SynchronousQueue).

Connection closed with error java.util.concurrent.RejectedExecutionException: Task org.jivesoftware.smack.tcp.XMPPTCPConnection$2@41dce200 rejected from java.util.concurrent.ThreadPoolExecutor@41d59150[Running, pool size = 3, active threads = 3, queued tasks = 0, completed tasks = 4]
