Currently if you restart docker daemon, all the containers with restart
policy `on-failure` regardless of its `RestartCount` will be started,
this will make daemon cost more extra time for restart.
This commit will stop these containers to do unnecessary start on
daemon's restart.

This fix tries to fix the issue in #21848 where `docker stats` will not correctly
display the container stats in case the container reuse another container's
network stack.
The issue is that when `stats` is performed, the daemon will check for container
network setting's `SandboxID`. Unfortunately, for containers that reuse another
container's network stack (`NetworkMode.IsConnected()`), SandboxID is not assigned.
Therefore, the daemon thinks the id is invalid and remote API will never return.
This fix tries to resolve the SandboxID by iterating through connected containers
and identify the appropriate SandboxID.
A test case for `stats` remote API has been added to check if `stats` will return
within the timeout.
This fix fixes#21848.

When user try to restart a restarting container, docker client report
error: "container is already active", and container will be stopped
instead be restarted which is seriously wrong.
What's more critical is that when user try to start this container
again, it will always fail.
This error can also be reproduced with a `docker stop`+`docker start`.
And this commit will fix the bug.

This fix tries to fix the discrepancy between API and CLI on hostname
validation. Previously, the hostname validation was handled at the
CLI interface in runconfig/opts/parse.go and return an error if the
hostname is invalid. However, if an end user use the remote API to
pass the hostname, the error will not be returned immediately.
Instead the error will only be thrown out when the container creation
fails. This creates behavior discrepancy between API and CLI.
In this fix, the hostname validation was moved to
verifyContainerSettings so the behavior will be the same for API and
CLI.
After the change, since CLI does not handle the hostname validation
any more, the previous unit tests about hostname validation on CLI
in runconfig/opts/parse_test.go has to be updated as well because
there is no validation at this stage. All those unit tests are moved
to integration test TestRunTooLongHostname so that the hostname
validation is still properly covered as before.
Note: Since the hostname validation moved to API, the error message
changes from `invalid hostname format for --hostname:` to
`invalid hostname format:` as well because `--hostname` is passed
to CLI only.
This fix fixes#21595.

When container is automatically restarted based on restart policy,
docker events can't get "start" event but only get "die" event, this is
not consistent with previous behavior. This commit will add "start"
event back.

For test that should be exclusively run only in regular daemon builds
and not in the experimental version, add a requirement.
Verified using TestCleanupMountsAfterDaemonKill.
- On regular daemon, the test ran.
- On experimental daemon, the test skipped.

Since the layer store was introduced, the level above the graphdriver
now differentiates between read/write and read-only layers. This
distinction is useful for graphdrivers that need to take special steps
when creating a layer based on whether it is read-only or not.
Adding this parameter allows the graphdrivers to differentiate, which
in the case of the Windows graphdriver, removes our dependence on parsing
the id of the parent for "-init" in order to infer this information.
This will also set the stage for unblocking some of the layer store
unit tests in the next preview build of Windows.

Kernel has no limit for memory reservation, but in different
kernel versions, the default behavior is different.
On kernel 3.13,
docker run --rm --memory-reservation 1k busybox cat /sys/fs/cgroup/memory/memory.soft_limit_in_bytes
the output would be 4096, but on kernel 4.1, the output is 0.
Since we have minimum limit for memory and kernel memory, we
can have this limit for memory reservation as well, to make
the behavior consistent.

The prior error message caused confusion. If a user attempts to push an
image up to a registry, but they misspelled (or forgot to properly tag
their image) they would see the message 'Repository does not exist', which
is not very clear and causes some to think that there might be a problem
with the registry or connectivity to it, when the problem was simply just
that an image with that tag specified does not exist locally.

Existing tests assume that the entrypoint in a docker run command will be
split into multiple arguments, which is inconsistent with Linux. Fix the
tests depending on this behavior.
