e98cae4919 Move filters package to the API.
These filters are only use to interchange data between clients and daemons.
They don't belong to the parsers package.

434d2e8745 Add PubSub topics.
A TopicFunc is an interface to let the pubisher decide whether it needs
to send a message to a subscriber or not. It returns true if the
publisher must send the message and false otherwise.

Users of the pubsub package can create a subscriber with a topic
function by calling `pubsub.SubscribeTopic`.

Message delivery has also been modified to use concurrent channels per
subscriber. That way, topic verification and message delivery is not
o(N+M) anymore, based on the number of subscribers and topic verification
complexity.

Using pubsub topics, the API stops controlling the message delivery,
delegating that function to a topic generated with the filtering
provided by the user. The publisher sends every message to the
subscriber if there is no filter, but the api doesn't have to select
messages to return anymore.

93d1dd8036 Make filtering a linear operation.
Improves the current filtering implementation complixity.
Currently, the best case is O(N) and worst case O(N^2) for key-value filtering.
In the new implementation, the best case is O(1) and worst case O(N), again for key-value filtering.

4352da7803 Update daemon and docker core to use new content addressable storage
Add distribution package for managing pulls and pushes. This is based on
the old code in the graph package, with major changes to work with the
new image/layer model.

Add v1 migration code.

Update registry, api/*, and daemon packages to use the reference
package's types where applicable.

Update daemon package to use image/layer/tag stores instead of the graph
package

b08f071e18 Revert "Merge pull request #16228 from duglin/ContextualizeEvents"
Although having a request ID available throughout the codebase is very
valuable, the impact of requiring a Context as an argument to every
function in the codepath of an API request, is too significant and was
not properly understood at the time of the review.

Furthermore, mixing API-layer code with non-API-layer code makes the
latter usable only by API-layer code (one that has a notion of Context).

This reverts commit de41640435, reversing
changes made to 7daeecd42d.

26b1064967 Add context.RequestID to event stream
This PR adds a "request ID" to each event generated, the 'docker events'
stream now looks like this:

```
2015-09-10T15:02:50.000000000-07:00 [reqid: c01e3534ddca] de7c5d4ca927253cf4e978ee9c4545161e406e9b5a14617efb52c658b249174a: (from ubuntu) create
```
Note the `[reqID: c01e3534ddca]` part, that's new.

Each HTTP request will generate its own unique ID. So, if you do a
`docker build` you'll see a series of events all with the same reqID.
This allow for log processing tools to determine which events are all related
to the same http request.

I didn't propigate the context to all possible funcs in the daemon,
I decided to just do the ones that needed it in order to get the reqID
into the events. I'd like to have people review this direction first, and
if we're ok with it then I'll make sure we're consistent about when
we pass around the context - IOW, make sure that all funcs at the same level
have a context passed in even if they don't call the log funcs - this will
ensure we're consistent w/o passing it around for all calls unnecessarily.

4026512a2c events/jsonmessage: add and prefer TimeNano for events
This way provide both Time and TimeNano in the event. For the display of
the JSONMessage, use either, but prefer TimeNano Proving only TimeNano
would break Subscribers that are using the `Time` field, so both are set
for backwards compatibility.

The events logging uses nano formatting, but only provides a Unix()
time, therefor ordering may get lost in the output. Example:
```
2015-09-15T14:18:51.000000000-04:00 ee46febd64ac629f7de9cd8bf58582e6f263d97ff46896adc5b508db804682da: (from busybox) resize
2015-09-15T14:18:51.000000000-04:00 a78c9149b1c0474502a117efaa814541926c2ae6ec3c76607e1c931b84c3a44b: (from busybox) resize
```

By having a field just for Nano time, when set, the marshalling back to
`time.Unix(sec int64, nsec int64)` has zeros exactly where it needs to.
This does not break any existing use of jsonmessage.JSONMessage, but now
allows for use of `UnixNano()` and get event formatting that has
distinguishable order. Example:
```
2015-09-15T15:37:23.810295632-04:00 6adcf8ed9f5f5ec059a915466cd1cde86a18b4a085fc3af405e9cc9fecbbbbaf: (from busybox) resize

```

09e7dd03f8 daemon/events: let Log be [slightly] blocking
With go1.5's concurrency, the use of a goroutine in Log'ing events was
causing the resulting events to not be in order.

386aefb9fc Make events test more deterministic in go1.5
Now scheduler makes order of events pretty random, so I added little
sleeps to make order intact. Also I renamed to test so name better
describes its nature.
