This allows using `Engine.Register` and `Engine.RegisterCatchall` on the
same engine without the catchall hiding all other handlers.

Installer is a standard interface for objects which can "install"
themselves an engine by registering handlers.
This can be used as an entrypoint for external plugins etc.

Without creating a root there is no way for the engine to return an
error from the new function.

This makes the engine more general purpose so that we can
use it and the job routing functionality for reexec'ing our binary

Conflicts:
integration/runtime_test.go
* The default behavior is preserved
* This disables the use of the `TEST` environment variable in engine.

This removes the incomplete symlink handling from engine.go and it adds
it one place in docker.go.
It also enables handling symlinks for TMPDIR.

Since commit c91c365, when starting the docker daemon without an
existing /var/lib/docker directory, it fails with:
2013/12/18 23:39:36 Unable to canonicalize root (%!s(*string=0xc210077c80)): lstat /var/lib/docker: no such file or directory
Move the symlink checking code to engine.New after the root dir has been
created.
Allow the user to set DOCKER_NOWARN_KERNEL_VERSION=1 to disable the
warning for RHEL 6.5 and other distributions that don't exhibit the
panics described in https://github.com/dotcloud/docker/issues/407.
* Jobs return an integer status instead of a string
* Status convention mimics unix process execution: 0=success, 1=generic error, 127="no such command"
* Stdout and Stderr support multiple thread-safe data receivers and ring buffer filtering
* Implement a new package: engine. It exposes a useful but minimalist job API.
* Refactor main() to instanciate an Engine instead of a Server directly.
* Refactor server.go to register an engine job.
This is the smallest possible refactor which can include the new Engine design
into master. More gradual refactoring will follow.
