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.

Using @mavenugo's patch for enabling the libcontainer pre-start hook to
be used for network namespace initialization (correcting the conflict
with user namespaces); updated the boolean check to the more generic
SupportsHooks() name, and fixed the hook state function signature.

- some method names were changed to have a 'Locking' suffix, as the
downcased versions already existed, and the existing functions simply
had locks around the already downcased version.
- deleting unused functions
- package comment
- magic numbers replaced by golang constants
- comments all over

Since the failure count of container will increase by 1 every time it
exits successfully, the compare in function shouldRestart() will stop
container to restart by the last time.

Function shouldRestart() checks the restart policy and records the
debug info and there should be two arguments in the log.Debugf().
Prior to the this patch, the logs were something like this:
- client: $ docker run --restart=on-failure:3 ubuntu /bin/sh -c 'exit 1'
- daemon: INFO[0168] ...
DEBU[0168] stopping restart of container %!s(int=3) because maximum
failure could of %!d(MISSING) has been reached
INFO[0086] ...
Btw, fix a spelling error in the same file:
- cotnainer -> container

Since the containers can handle the out of memory kernel kills gracefully, docker
will only provide out of memory information as an additional metadata as part of
container status.

Reset the time increment if the container's execution time is greater
than 10s or else as a container runs and is restarted the time will grow
overtime.

We need to do this so that when a user asks docker to stop the container
and it is currently in the restart loop we don't want to have to wait
for the duration of the restart time increment before ack. the stop.
