This changes the way the exec drivers work by not specifing a -driver
flag on reexec. For each of the exec drivers they register their own
functions that will be matched aginst the argv 0 on exec and called if
they match.
This also allows any functionality to be added to docker so that the
binary can be reexec'd and any type of function can be called. I moved
the flag parsing on docker exec to the specific initializers so that the
implementations do not bleed into one another. This also allows for
more flexability within reexec initializers to specify their own flags
and options.

This removes a shim `daemon.Server` interface which was used to start
separating Daemon from Server *gradually*, without getting cyclic
dependency errors.
Now that the last Daemon->Server dependency has been removed, we can
finally remove the shim. Yay!

This disentangles the following functions, which were previously all mixed together:
* 1) Waiting for jobs to terminate when shutting down
* 2) Handling signals in the Docker daemon
* 3) Per-subsystem cleanup handlers
* 4) pidfile management
Responsibilities are dispatched as follows:
* Signal traps are set in `main`, and trigger `engine.Shutdown`
* `engine.Shutdown` coordinates cleanup by waiting for jobs to complete, and calling shutdown handlers
* To perform cleanup at shutdown, each subsystem registers handlers with `engine.OnShutdown`
* `daemon` is one subsystem, so it registers cleanup via `engine.OnShutdown`.
* `daemon` owns the pidfile, which is used to lock access to `/var/lib/docker`. Part of its cleanup is to remove the pidfile.

`rm -f` was originally deprecated in favor of `rm --stop/--kill` since `rm
-f` was sending SIGTERM and potentially very slow.
Instead this will bring back `rm -f` but use SIGKILL isntead

* Events subsystem merged from `server/events.go` and
`utils/jsonmessagepublisher.go` and moved to `events/events.go`
* Only public interface for this subsystem is engine jobs
* There is two new engine jobs - `log_event` and `subscribers_count`
* There is auxiliary function `container.LogEvent` for logging events for
containers

Note: this cannot yet be moved to graph/ because of a lingering

/tmp is often a tmpfs file system and large temporary files could cause
docker commands to fail. Also using /tmp potentially allows users on the
system to get access to content, or even attack the content. Moving the tmpdir to
/var/lib/container/tmp will protect the data.
