This endpoint was deprecated in API v1.20 (Docker Engine v1.8.0) in
commit db9cc91a9e, in favor of the
`PUT /containers/{id}/archive` and `HEAD /containers/{id}/archive`
endpoints, and disabled in API v1.24 (Docker Engine v1.12.0) through
commit 428328908d.
This patch removes the endpoint, and the associated `daemon.ContainerCopy`
method in the backend.

Define consts for the Actions we use for events, instead of "ad-hoc" strings.
Having these consts makes it easier to find where specific events are triggered,
makes the events less error-prone, and allows documenting each Action (if needed).

Mounting a container's volumes under its rootfs directory inside the
host mount namespace causes problems with cross-namespace mount
propagation when /var/lib/docker is bind-mounted into the container as a
volume. The mount event propagates into the container's mount namespace,
overmounting the volume, but the propagated unmount events do not fully
reverse the effect. Each archive operation causes the mount table in the
container's mount namespace to grow larger and larger, until the kernel
limiton the number of mounts in a namespace is hit. The only solution to
this issue which is not subject to race conditions or other blocker
caveats is to avoid mounting volumes into the container's rootfs
directory in the host mount namespace in the first place.
Mount the container volumes inside an unshared mount namespace to
prevent any mount events from propagating into any other mount
namespace. Greatly simplify the archiving implementations by also
chrooting into the container rootfs to sidestep the need to resolve
paths in the host.

It is only applicable to Windows so it does not need to be called from
platform-generic code. Fix locking in the Windows implementation.

The Linux implementation needs to diverge significantly from the Windows
one in order to fix platform-specific bugs. Cut the generic
implementation out of daemon/archive.go and paste identical, verbatim
copies of that implementation into daemon/archive_{windows,linux}.go to
make it easier to compare the progression of changes to the respective
implementations through Git history.

It was only used in a single location, and the ErrVolumeReadonly was not checked
for, or used as a sentinel error.
This error was introduced in c32dde5baa. It was
never used as a sentinel error, but from that commit, it looks like it was added
as a package variable to mirror already existing errors defined at the package
level.
This patch removes the exported variable, and replaces the error with an
errdefs.InvalidParameter(), so that the API also returns the correct (400)
status code.

This changes mounts.NewParser() to create a parser for the current operatingsystem,
instead of one specific to a (possibly non-matching, in case of LCOW) OS.
With the OS-specific handling being removed, the "OS" parameter is also removed
from `daemon.verifyContainerSettings()`, and various other container-related
functions.

This moves the platform specific stuff in a separate package and keeps
the `volume` package and the defined interfaces light to import.

Currently, daemonbuilder package (part of daemon) implemented the
builder backend. However, it was a very thin wrapper around daemon
methods and caused an implementation dependency for api/server build
endpoint. api/server buildrouter should only know about the backend
implementing the /build API endpoint.
Removing daemonbuilder involved moving build specific methods to
respective files in the daemon, where they fit naturally.

So other packages don't need to import the daemon package when they
want to use this struct.
