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
```

5994c9efbf skip_leave_on_int's default changes based on agent mode 
`skip_leave_on_int`'s behavior now changes based on whether or not the agent is acting as a client or server.

9fb64ab114 Allow adjusting the number of DNS records in a response... 
Based on work done by @fusiondog in #1583, extend the concept to use an integer instead of a boolean.

7af6a94edb Factor out duplicate functions into a lib package 
Consolidate code duplication and tests into a single lib package.  Most of these functions were from various **/util.go functions that couldn't be imported due to cyclic imports.  The consul/lib package is intended to be a terminal node in an import DAG and a place to stash various consul-only helper functions.  Pulled in hashicorp/go-uuid instead of consolidating UUID access.

267e0caf81 Implement advertise_addrs for SerfLan, SerfWan and RPC. 
Fixes #550.
This will make it possible to configure the advertised adresses for
SerfLan, SerfWan and RPC. It will enable multiple consul clients on a
single host which is very useful in a container environment.

This option might override advertise_addr and advertise_addr_wan
depending on the configuration.

It will be configureable with advertise_addrs. Example:

{
  "advertise_addrs": {
    "serf_lan": "10.0.120.91:4424",
    "serf_wan": "201.20.10.61:4423",
    "rpc": "10.20.10.61:4424"
  }
}

cb764c35e5 add ability to specify response headers on the HTTP API 
Add an config object that allows adding HTTP header response fields to every
HTTP API response.

Each specified header is added to every response from all HTTP API endpoints.
Each individual endpoint may overwrite the specified header, which makes sure
that Consul headers such as 'X-Consul-Index' is enforced by the API.
