Also requires some tests to be updated which relied on behavior
of a busybox image that wasn't actually "busybox:latest"; meaning these
tests were unable to be verified/run against a real busybox:latest image
on a daemon.

Adds support for the daemon to handle user namespace maps as a
per-daemon setting.
Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

It prevents occupying of those resources (ports, unix-sockets) by
containers.
Also fixed false-positive test for that case.

- Print the mount table as in /proc/self/mountinfo
- Do not exit prematurely when one of the ipc mounts doesn't exist.
- Do not exit prematurely when one of the ipc mounts cannot be unmounted.
- Add a unit test to see if the cleanup really works.
- Use syscall.MNT_DETACH to cleanup mounts after a crash.
- Unmount IPC mounts when the daemon unregisters an old running container.

If an invalid logger address is provided on daemon start it will
silently fail. As syslog driver is doing, this check should be done on
daemon start and prevent it from starting even in other drivers.
This patch also adds integration tests for this behavior.

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.

libnetwork host, none and bridge driver initialization is incorrectly
disabled if the daemon flag --bridge=none. The expected behavior of
setting --bridge as none is to disable the bridge driver alone and let
all other modes to be operational.

DOCEKR_TLS_VERIFY was being ignored because we were just checking if the
`-tlsverify` flag was set, not the actual value, which is defaulted to
the value of `os.Getenv("DOCKER_TLS_VERIFY") != ""`
The problem that this specifically fixes is where the client has set the
`DOCKER_TLS_VERIFY` env var but is connecting to a daemon that is not
verifed.
