It may happen that host system settings are changed while the daemon is running.
This will cause errors at libcontainer level when starting a container with a
particular hostConfig (e.g. hostConfig with memory swappiness but the memory
cgroup was umounted).
This patch adds an hostConfig check on container start to prevent the daemon
from even calling libcontainer with the wrong configuration as we're already
doing on container's creation).

sysinfo struct was initialized at daemon startup to make sure
kernel configs such as device cgroup are present and error out if not.
The struct was embedded in daemon struct making impossible to detect
if some system config is changed at daemon runtime (i.e. someone
umount the memory cgroup). This leads to container's starts failure if
some config is changed at daemon runtime.
This patch moves sysinfo out of daemon and initilize and check it when
needed (daemon startup, containers creation, contaienrs startup for
now).

This patch splits LookupEndpoints into LookupPullEndpoints and
LookupPushEndpoints so that mirrors added with --registry-mirror are
skipped in the list returned by LookupPushEndpoints.

I just tried the installation but docker didn't start automatically. So I had to execute the newly added command in order to get the hello-world verification running.

The docker script in contrib/init/sysvinit-redhat will fail silently on
a start if Docker is not installed in the default /usr/bin/ location.
While a non-zero exit code is returned the user will receive no visible
indication (i.e. error message) as to why Docker was not started.
This commit changes the logic so that in the case that the docker
executable is not found in the expected location or the user does not
have execute permissions on the executable appropriate error messages
are now shown to the user as well as exiting with a non-zero exit code

Component: engine
The process of pulling an image spawns a new goroutine for each layer in the
image manifest. If any of these downloads fail we would stop everything and
return the error, even though other goroutines would still be running and
writing output through a progress reader which is attached to an http response
writer. Since the request handler had already returned from the first error,
the http server panics when one of these download goroutines makes a write to
the response writer buffer.
This patch prevents this crash in the daemon http server by waiting for all of
the download goroutines to complete, even if one of them fails. Only then does
it return, terminating the request handler.
