The remote API allows full privilege escalation and is equivalent to
having root access on the host. Because of this, the API should never
be accessible through an insecure connection (TCP without TLS, or TCP
without TLS verification).
Although a warning is already logged on startup if the daemon uses an
insecure configuration, this warning is not very visible (unless someone
decides to read the logs).
This patch attempts to make insecure configuration more visible by sending
back warnings through the API (which will be printed when using `docker info`).

When requesting information about the daemon's configuration through the `/info`
endpoint, missing features (or non-recommended settings) may have to be presented
to the user.
Detecting these situations, and printing warnings currently is handled by the
cli, which results in some complications:
- duplicated effort: each client has to re-implement detection and warnings.
- it's not possible to generate warnings for reasons outside of the information
returned in the `/info` response.
- cli-side detection has to be updated for new conditions. This means that an
older cli connecting to a new daemon may not print all warnings (due to
it not detecting the new conditions)
- some warnings (in particular, warnings about storage-drivers) depend on
driver-status (`DriverStatus`) information. The format of the information
returned in this field is not part of the API specification and can change
over time, resulting in cli-side detection no longer being functional.
This patch adds a new `Warnings` field to the `/info` response. This field is
to return warnings to be presented by the user.
Existing warnings that are currently handled by the CLI are copied to the daemon
as part of this patch; This change is backward-compatible with existing
clients; old client can continue to use the client-side warnings, whereas new
clients can skip client-side detection, and print warnings that are returned by
the daemon.
Example response with this patch applied;
```bash
curl --unix-socket /var/run/docker.sock http://localhost/info | jq .Warnings
```
```json
[
"WARNING: bridge-nf-call-iptables is disabled",
"WARNING: bridge-nf-call-ip6tables is disabled"
]

* Expose license status in Info
This wires up a new field in the Info payload that exposes the license.
For moby this is hardcoded to always report a community edition.
Downstream enterprise dockerd will have additional licensing logic wired
into this function to report details about the current license status.

This implements chown support on Windows. Built-in accounts as well
as accounts included in the SAM database of the container are supported.
NOTE: IDPair is now named Identity and IDMappings is now named
IdentityMapping.
The following are valid examples:
ADD --chown=Guest . <some directory>
COPY --chown=Administrator . <some directory>
COPY --chown=Guests . <some directory>
COPY --chown=ContainerUser . <some directory>
On Windows an owner is only granted the permission to read the security
descriptor and read/write the discretionary access control list. This
fix also grants read/write and execute permissions to the owner.

This change adds a Platform struct with a Name field and a general
Components field to the Version API type. This will allow API
consumers to show version information for the whole platform and
it will allow API providers to set the versions for the various
components of the platform.
All changes here are backwards compatible.

plugins exist in a chain that composes potentially mutating requests and
responses. This simply reverts the sorting of AuthZ plugins so that the
/info API endpoint returns the internal ordering used for AuthZ composition.
Volume driver plugins are not affected because they are just a set.

Container state counts are used for reporting in the `/info` endpoint.
Currently when `/info` is called, each container is iterated over and
the containers 'StateString()' is called. This is not very efficient
with lots of containers, and is also racey since `StateString()` is not
using a mutex and the mutex is not otherwise locked.
We could just lock the container mutex, but this is proven to be
problematic since there are frequent deadlock scenarios and we should
always have the `/info` endpoint available since this endpoint is used
to get general information about the docker host.
Really, these metrics on `/info` should be deprecated. But until then,
we can just keep a running tally in memory for each of the reported
states.

This fix tries to address the issue raised in #24374 where
`docker info` outputs seccomp support in Ubuntu 14.04 but
the seccomp wass not actually supported.
The issue is that in the current docker implementation, seccomp
support is only checked against the kernel by inspect CONFIG_SECCOMP
and CONFIG_SECCOMP_FILTER. However, seccomp might not be enabled
when building docker (through golang build flag).
This fix adds a supportSeccomp boolean variable. The supportSeccomp
is only set to true when seccomp is enabled when building docker.
This fix fixes#24374.

This fix follows the suggestion from #23768 and replace go's `runtime.NumCPU()`
with `sysconf(_SC_NPROCESSORS_ONLN)` so that correct CPU count could
be obtained even after CPU hot-plugging.
This fix is tested manually, as is suggested in #23768.
