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.

This vendors in new spec/runc that supports
setting readonly and masked paths in the
configuration. Using this allows us to make an
exception for `—-privileged`.

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.

Also modify an integration test that hardcoded the error string so it
uses the exported error variable from libcontainer/user.

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.

Fix unmount issues in the daemon crash and restart lifecycle, w.r.t
graph drivers. This change sets a live container RWLayer's activity
count to 1, so that the RWLayer is aware of the mount. Note that
containerd has experimental support for restore live containers.
Added/updated corresponding tests.

The current error message is "Error: image [name] not found". This makes
sense from the perspective of the v1 pull, since we found the repository
doesn't exist over the v1 protocol. However, in the vast majority of
cases, this error will be produced by fallback situations, where we
first try to pull the tag with the v2 protocol, and then fall back the
v1 protocol, which probably isn't even supported by the server.
Including the tag in the error message makes a lot more sense since the
actual repository may exist on v2, but not the tag.
