The agent configuration for the consul server is a partial configuration
which needs to be cloned to avoid data races.
This is a stop-gap measure before moving the configuration into
a separate package.
The tests that use the localState of the agent access the internal
variables and call methods which are not guarded by locks creating
data races in tests. While the use of internal variables is somewhat
easy to spot the fact that not all methods are thread-safe is a
surprise.
A proper fix requires the localState struct to be moved into its own
package so that tests in the agent can only access the external
interface.
However, the localState is currently dependent on the agent.Config
which would create a circular dependency. Therefore, the Config
struct needs to be moved first for this to happen.
This patch literally monkey patches the use of the lock around the
cases which have data races and marks them with a
// todo(fs): data race comment.
The sessionTimers map was secured by a lock which wasn't used
properly in the tests. This lead to data races and failing tests
when accessing the length or the members of the map.
This patch adds a separate SessionTimers struct which is safe
for concurrent use and which ecapsulates the behavior of the
sessionTimers map.
When using dynamic ports for the serf clusters then
the actual bind port of the serf WAN cluster needs to
be discovered before the serf LAN cluster is started
since the serf LAN cluster announces the port of the WAN
cluster.

This picks up the fix for https://github.com/hashicorp/raft/issues/212,
which can cause out-of-date followers to get stuck in a loop trying to
sync because they don't discard old snapshot data.
There's some incidental reordering of the vendor.json since the last
update to that file was merged by hand.
