--help and help are successful commands so output should not go to error.
QE teams have requested this change, also users doing docker help | less
or docker run --help | less would expect this to work.
Usage statement should only be printed when the user asks for it.
Errors should print error message and then suggest the docker COMMAND --help
command to see usage information.
The current behaviour causes the user to have to search for the error message
and sometimes scrolls right off the screen. For example a error on a
"docker run" command is very difficult to diagnose.
Finally erros should always exit with a non 0 exit code, if the user
makes a CLI error.

This way, we can embed the link/description lines directly in the array itself, conflicts between PRs to this section are minimized, new PRs are easier to review, and it's a lot easier to notice when people are missing a link/description (like the few that currently are).

To avoid an expensive call to archive.ChangesDirs() which walks two directory
trees and compares every entry, archive.ApplyLayer() has been extended to
also return the size of the layer changes.

When the user is not using the full has to retrieve a container it's
possible that we find conflicts with the ids of other containers.
At the moment it's just failing saying that it can not find a container,
but it doesn't say why. Adding a small log saying that duplicates where
found is going to help the user.

This makes sure that we don't buffer in memory and that we also flush

Another update to TarSum tests, this patch fixes an issue where
the benchmarks were generating archives incorrectly by not closing
the tarWriter.

With 32ba6ab from #9261, TempArchive now closes the underlying file and
cleans it up as soon as the file's contents have been read. When pushing
an image, PushImageLayerRegistry attempts to call Close() on the layer,
which is a TempArchive that has already been closed. In this situation,
Close() returns an "invalid argument" error.
Add a Close method to TempArchive that does a no-op if the underlying
file has already been closed.

These two cases did not actually read the same content with each iteration
of the benchmark. After the first read, the buffer was consumed. This patch
corrects this by using a bytes.Reader and seeking to the beginning of the
buffer at the beginning of each iteration.
Unfortunately, this benchmark was not actually as fast as we believed. But
the new results do bring its results closer to those of the other benchmarks.

Currently devicemapper CreateDevice and CreateSnapDevice keep on retrying
device creation till a suitable device id is found.
With new transaction mechanism we need to store device id in transaction
before it has been created.
So change the logic in such a way that caller decides the devices Id to
use. If that device Id is not available, caller bumps up the device Id
and retries.
That way caller can update transaciton too when it tries a new Id. Transaction
related patches will come later in the series.
