Make the code slightly more idiomatic; remove some "var" declarations,
remove some intermediate variables and redundant error-checks, and remove
the filePerm const.

This boolean was not used anywhere, so we can remove it. Also cleaning up
the implementation a bit.

The WriteOptions struct was only used to set the "IsDir" option. This option
was added in d635a8e32b
and was only supported by the etcd libkv store.
The BoltDB store does not support this option, making the WriteOptions
struct fully redundant.

The only remaining kvstore is BoltDB, which doesn't use TLS connections
or authentication, so we can remove these options.

Allow SetMatrix to be used as a value type with a ready-to-use zero
value. SetMatrix values are already non-copyable by virtue of having a
mutex field so there is no harm in allowing non-pointer values to be
used as local variables or struct fields. Any attempts to pass around
by-value copies, e.g. as function arguments, will be flagged by go vet.

Perhaps the testutils package in the past had an `init()` function to set up
specific things, but it no longer has. so these imports were doing nothing.

After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

While doing a boltdb operation and if the bucket is not found
we should not return a boltdb specific bucket not found error
because this causes leaky abstraction where in the user of libkv
needs to know about boltdb and import boltdb dependencies
neither of which is desirable. Replaced all the bucket not found
errors with the more generic `store.ErrKeyNotFound` error which
is more appropriate.

When using AtomicPut with 'previous' set at nil, it interprets
that the Key should be created with the AtomicPut. Instead of
returning a generic error, we return store.ErrKeyExists if the
key exists in the store during the operation.

Currently boltdb uses a handle which can be accessed
concurrently from multiple go routines and all of them
trying to open and close the boldb db handle which can
cause havoc. Use a mutex to serialize db access and
handle access.

This commit migrates the old 'go-etcd' client, which is deprecated
to the new 'coreos/etcd/client'.
One notable change is the ability to specify an 'IsDir' parameter
to the 'Put' call. This allows to circumvent the limitations of etcd
regarding the key/directory distinction while setting up Watches on
a directory. A conservative measure to set up a watch that should be
used the same way for etcd/consul/zookeeper is to enforce the 'IsDir'
parameter with 'WriteOptions' on 'Put' to avoid the 'NotANode' error
thrown by etcd on Watch call. Consul and zookeeper are not using the
'IsDir' parameter.
