Sean Chittenden 45bd128f12 Rely exclusively on error to signal failure 
Pointed out by: slackpad
 2016-04-01 10:34:45 -07:00
Sean Chittenden 7a814fce63 Print a helpful message re: duplicate addresses 
IP sockets provide nice endpoints where the kernel will fail to bind and will error out saying socket already in use.  UNIX sockets, however, don't enjoy this nice property when cleaning up stale sockets on listen.  Given the number of addresses in Consul, provide operators with a helpful message that indicates the source of the reused address.

Before this fix, it was possible for the HTTP socket to unlink the RPC socket, leading to confusing blocked behavior when running commands like `consul info`.

```
% cat tmp.config.json
{
    "addresses": {
	"http": "unix:///tmp/.consul.sock",
	"rpc": "unix:///tmp/.consul.sock"
    },
    "unix_sockets": {
	"mode": "0700"
    }
}
% consul agent -config-file tmp.config.json -advertise=127.0.0.1 -data-dir=/tmp/
==> All listening endpoints must be unique: HTTP address already configured for RPC
Exit 1
```

Sean Chittenden 5ba7e74bb8 Use table-driven test for response limits 
Much more exhaustive testing and shows where the limits are of the 512B limitation (quering by ID is less space efficient than querying by just a prepared query or service).
