- iptables pkg functions are coded to discard
the xtables_lock error message about acquiring
the lock, because all the calls are done with
the wait logic. But the error message has
slightly changed between iptables 1.4.x and 1.6.
This lead to false positives causing docker
network create to fil in presence of concurrent calls.
- Fixed message mark to be common among the two main versions.

- Fix npe in sbJoin error path
- Fail again endpoint Join in case of failure
in programming the external connectivity
- In bridge, look for parent and child container configs
in the generic data
- iptables.Exists() might be called before any other call to
iptables.raw(). We need to call checkInit() then.

The `iptables.Exists` function is wrong in two ways:
1. The iptables -C call doesn't add `-j DOCKER` and fails to match
2. The long path takes ordering into account in comparison and fails to match
This patch fixes issue 1 by including `-j DOCKER` in the check.
