Treat return code -1 as error instead.
People from glibc say that errno is undefined in case of successful
sysconf call according to POSIX standard:
Glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=21536
More over in sysconf man it is wrongly said that "errno is not changed"
on success. So I've created a bug to man-pages:
https://bugzilla.kernel.org/show_bug.cgi?id=195955
Background: Glibc's sysconf(_SC_NPROCESSORS_ONLN) changes errno to
ENOENT, if there is no /sys/devices/system/cpu/online file, while
the call itself is successful. In Virtuozzo containers we prohibit
most of sysfs files for security reasons. So we have Run():daemon
/stats/collector.go infinitely loop never actualy collecting stats
from publisher pairs.

This fixes an issue where if a stop signal is set, and a user sends
SIGKILL, `container.ExitOnNext()` is not set, thus causing the container
to restart.

When closing the log-file, and the file is already
closed, there's no need to log an error.
This patch adds a `closed` boolean to check if the
file was closed, and if so, skip closing the file.
This prevents errors like this being logged:
level=error msg="Error closing logger: invalid argument"

OverlayFS is supported on top of btrfs as of Linux Kernel 4.7.
Skip the hard enforcement when on kernel 4.7 or newer and
respect the kernel check override flag on older kernels.

The commit adds capability to accept csv parameters
for network option in service create/update commands.The change
includes name,alias driver options specific to the network.
With this the following will be supported

docker service create --name web --network docknet nginx
docker service update web --network-add name=docknet,alias=web1,driver-opt=field1=value1

- They are configuration-only networks which
can be used to supply the configuration
when creating regular networks.
- They do not get allocated and do net get plumbed.
Drivers do not get to know about them.
- They can be removed, once no other network is
using them.
- When user creates a network specifying a
configuration network for the config, no
other network specific configuration field
is are accepted. User can only specify
network operator fields (attachable, internal,...)

This is necessary because normally `apparmor_parser -r` will try to
create a temporary directory on the host (which is not allowed if the
host has a rootfs). However, the -K option bypasses saving things to the
cache (which avoids this issue).
% apparmor_parser -r /tmp/docker-profile
mkstemp: Read-only file system
% apparmor_parser -Kr /tmp/docker-profile
%
In addition, add extra information to the ensureDefaultAppArmorProfile
errors so that problems like this are easier to debug.

This patch adds the untilRemoved option to the ContainerWait API which
allows the client to wait until the container is not only exited but
also removed.
This patch also adds some more CLI integration tests for waiting for a
created container and waiting with the new --until-removed flag.

Apply container wait changes to API 1.30
The set of changes to the containerWait API missed the cut for the
Docker 17.05 release (API version 1.29). This patch bumps the version
checks to use 1.30 instead.
This patch also makes a minor update to a testfile which was added to
the builder/dockerfile package.

Address more ContainerWait review comments
- Update ContainerWait backend interface to not return pointer values
for container.StateStatus type.
- Updated container state's Wait() method comments to clarify that a
context MUST be used for cancelling the request, setting timeouts,
and to avoid goroutine leaks.
- Removed unnecessary buffering when making channels in the client's
ContainerWait methods.
- Renamed result and error channels in client's ContainerWait methods
to clarify that only a single result or error value would be sent
on the channel.

This patch consolidates the two WaitStop and WaitWithContext methods
on the container.State type. Now there is a single method, Wait, which
takes a context and a bool specifying whether to wait for not just a
container exit but also removal.
The behavior has been changed slightly so that a wait call during a
Created state will not return immediately but instead wait for the
container to be started and then exited.
The interface has been changed to no longer block, but instead returns
a channel on which the caller can receive a *StateStatus value which
indicates the ExitCode or an error if there was one (like a context
timeout or state transition error).
These changes have been propagated through the rest of the deamon to
preserve all other existing behavior.

The --allow-nondistributable-artifacts daemon option specifies
registries to which foreign layers should be pushed. (By default,
foreign layers are not pushed to registries.)
Additionally, to make this option effective, foreign layers are now
pulled from the registry if possible, falling back to the URLs in the
image manifest otherwise.
This option is useful when pushing images containing foreign layers to a
registry on an air-gapped network so hosts on that network can pull the
images without connecting to another server.
