if there is no cookie set in dm task, or flag DM_UDEV_DISABLE_LIBRARY_FALLBACK
is cleared for a DM_DEV_REMOVE task, libdevmapper will fallback to clean up the
symlink under /dev/mapper by itself, no matter the device removal is executed
immediately or deferred by the kernel.In some cases, the removal is deferred by the
kernel, while the symlink is deleted directly by libdevmapper, when docker tries to
activate the device again, the deferred removal will be canceld, but the symlink will
not show up again, so docker's attempt to mount the device by the symlink will fail,
and it will eventually leads to a `docker start/diff` error.

This fix tries to address the issue raised in 25927 where
the HTTP headers have been chaged when AUthZ plugin is in
place.
This issue is that in `FlushAll` (`pkg/authorization/response.go`),
the headers have been written (with `WriteHeader`) before all the
headers have bee copied.
This fix fixes the issue by placing `WriteHeader` after.
A test has been added to cover the changes.`

SetConsoleMode() on input handles appears to remember invalid bits that
were set, causing problems for other programs (such as xcopy.exe) trying
to set the console mode after docker.exe has exited. Always restore
the input console mode on set failure.

Legacy plugin model maintained a map of plugins. This is
not used by the new model. Using this map in the new model
causes incorrect lookup of plugins. This change uses adds

Always enable VT output emulation when starting the process so that

Also remove the version block for using the native console and just rely

This reduces memory usage with a lot of docker proxy processes.
On Docker for Mac we are currently carrying a patch to replace
the binary as we modify it to forward ports to the Mac rather
than the Linux VM, this allows us to simply replace this binary
in our packaging with one that has a compatible interface. This
patch does not provide an easy way to substitute a binary as
the interface is complex and there are few use cases, but where
needed this can be done.

Currently when overlay creates a whiteout file then the overlay2 layer is archived,
the correct tar header will be created for the whiteout file, but the tar logic will then attempt to open the file causing a failure.
When tar encounters such failures the file is skipped and excluded for the archive, causing the whiteout to be ignored.
By skipping the copy of empty files, no open attempt will be made on whiteout files.

This patch introduces a new experimental engine-level plugin management
with a new API and command line. Plugins can be distributed via a Docker
registry, and their lifecycle is managed by the engine.
This makes plugins a first-class construct.
For more background, have a look at issue #20363.
Documentation is in a separate commit. If you want to understand how the
new plugin system works, you can start by reading the documentation.
Note: backwards compatibility with existing plugins is maintained,
albeit they won't benefit from the advantages of the new system.

This is similar to network scopes where a volume can either be `local`
or `global`. A `global` volume is one that exists across the entire
cluster where as a `local` volume exists on a single engine.
