This PR has the API changes described in https://github.com/moby/moby/issues/34617.
Specifically, it adds an HTTP header "X-Requested-Platform" which is a JSON-encoded
OCI Image-spec `Platform` structure.
In addition, it renames (almost all) uses of a string variable platform (and associated)
methods/functions to os. This makes it much clearer to disambiguate with the swarm
"platform" which is really os/arch. This is a stepping stone to getting the daemon towards
fully multi-platform/arch-aware, and makes it clear when "operating system" is being
referred to rather than "platform" which is misleadingly used - sometimes in the swarm
meaning, but more often as just the operating system.
Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

Reuse existing structures and rely on json serialization to deep copy
Container objects.
Also consolidate all "save" operations on container.CheckpointTo, which
now both saves a serialized json to disk, and replicates state to the
ACID in-memory store.

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.

If a caller specifies an SELinux type or MCS Label and still wants to
share an IPC Namespace or the host namespace, we should allow them.
Currently we are ignoring the label specification if ipcmod=container
or pidmode=host.

This fix tries to address the issue raised in 29129 where
"--hostname" not working when running in "--net=host" for
`docker run`.
The fix fixes the issue by not resetting the `container.Config.Hostname`
if the `Hostname` has already been assigned through `--hostname`.
An integration test has been added to cover the changes.

init layer is read/write layer and not read only layer. Following commit
introduced new graph driver method CreateReadWrite.
ef5bfad Adding readOnly parameter to graphdriver Create method
So far only windows seem to be differentiating between above two methods.
Making this change to make sure -init layer calls right method so that
we don't have surprises in future.
Windows does not need init layer. This patch also gets rid of creation of
init layer on windows.

This PR adds support for running regular containers to be connected to
swarm mode multi-host network so that:
- containers connected to the same network across the cluster can
discover and connect to each other.
- Get access to services(and their associated loadbalancers)
connected to the same network

This fix tries to address the issue raised in comment:
https://github.com/docker/docker/pull/25943#discussion_r76843081
Previously, the validation for `ip6` is done by checking ParseIP().To16().
However, in case an IPv4 address or an IPv4-mapped Ipv6 address has been
provided, the validation will pass (should fail).
This fix first check if `--ip6` is passed with a valid IP address and returns
error for invalid IP addresses. It then check if an IPv4 or IPv4-mapped Ipv6
address is passed, and return error accordingly.
This fix adds two more cases in the tests. One for IPv4 address passed to `--ip6`
and another for Ipv4-mapped IPv6 address passed to `--ip6`. In both cases,
without this fix the validation will pass through.

This fix tries to fix the issue raised in 25863 where `--ip` value
is not validated for `docker create`. As a result, the IP address
passed by `--ip` is not used for `docker create` (ignored silently).
This fix adds validation in the daemon so that `--ip` and `--ip6`
are properly validated for `docker create`.
An integration test has been added to cover the changes.

fixes#25766
If a container's AutoRemove is enabled, client will wait until it's
removed after container exits, this is implemented based on "destroy"
event.
Currently an "AutoRemove" container will report "destroy" event to
notify a hanging client to exit before all volumes are removed, this is
wrong, we should wait container until everything is cleaned up.
