Fix container register failed during daemon start and then start the container
Upstream-commit: db2ac8655d046b97b33636077faa420a700d8bfc

Volumes are accounted when a container is created.
If the creation fails we should remove the reference from the counter.
Do not log ErrVolumeInUse as an error, having other volume references is
not an error.

This is the first step in converting out static strings into well-defined
error types. This shows just a few examples of it to get a feel for how things
will look. Once we agree on the basic outline we can then work on converting
the rest of the code over.

@noxiouz points out that we don't need to check for a nil result from
C.CString(), since an out-of-memory condition causes a runtime panic
instead.

This is not a public interface and users are trying to use it.
We only use it to be able to generate the rpc protocol to talk with a plugin.

If a logdriver doesn't register a callback function to validate log
options, it won't be usable. Fix the journald driver by adding a dummy
validator.
Teach the client and the daemon's "logs" logic that the server can also
supply "logs" data via the "journald" driver. Update documentation and
tests that depend on error messages.
Add support for reading log data from the systemd journal to the
journald log driver. The internal logic uses a goroutine to scan the
journal for matching entries after any specified cutoff time, formats
the messages from those entries as JSONLog messages, and stuffs the
results down a pipe whose reading end we hand back to the caller.
If we are missing any of the 'linux', 'cgo', or 'journald' build tags,
however, we don't implement a reader, so the 'logs' endpoint will still
return an error.
Make the necessary changes to the build setup to ensure that support for
reading container logs from the systemd journal is built.
Rename the Jmap member of the journald logdriver's struct to "vars" to
make it non-public, and to make it easier to tell that it's just there
to hold additional variable values that we want journald to record along
with log data that we're sending to it.
In the client, don't assume that we know which logdrivers the server
implements, and remove the check that looks at the server. It's
redundant because the server already knows, and the check also makes
using older clients with newer servers (which may have new logdrivers in
them) unnecessarily hard.
When we try to "logs" and have to report that the container's logdriver
doesn't support reading, send the error message through the
might-be-a-multiplexer so that clients which are expecting multiplexed
data will be able to properly display the error, instead of tripping
over the data and printing a less helpful "Unrecognized input header"
error.

This PR makes a user visible behavior change with userland
proxy disabled by default and rely on hairpin NAT to be enabled
by default. This may not work in older (unsupported) kernels
where the user will be forced to enable userlandproxy if needed.
- Updated the Docs
- Changed the integration-cli to start with userlandproxy
desiabled by default.

The original purpose of this was to cancel downloads if pullV2Tag
returns an error, preventing an associated crash (see #15353). The
broadcaster now accomplishes the same thing that the pipe does, making
the pipe redundant. When pullV2Tag returns, all broadcasters are closed,
which means all further writes to those broadcasters will return errors.

Before, this only waited for the download to complete. There was no
guarantee that the layer had been registered in the graph and was ready
use. This is especially problematic with v2 pulls, which wait for all
downloads before extracting layers.
Change Broadcaster to allow an error value to be propagated from Close
to the waiters.
Make the wait stop when the extraction is finished, rather than just the
download.
This also fixes v2 layer downloads to prefix the pool key with "layer:"
instead of "img:". "img:" is the wrong prefix, because this is what v1
uses for entire images. A v1 pull waiting for one of these operations to
finish would only wait for that particular layer, not all its
dependencies.
