W/o this (and set to "1") we'll see something like this error
when running:
System error: write /cgroup/cpuset/docker/66689499bbd08cd8dccc9b7bfd1d6b34e85d73ce8c84d3c69b5e91944322da60/docker/79d7c548b58c85c4cfad6cd01eb7c3b30db254d1014c496137edd93ddc528a6f/cpuset.cpus: invalid argument"

The validation script from #10681 is too pedantic, and does not handle
well situations like:
```
cat <<EOF # or <<-EOF
Whether the leading whitespace is stripped out or not by bash
it should still be considered as valid.
EOF
```

Add the capability to cancel the build by disconnecting the client.
This adds a `cancelled` channel which is used to signal that a build
should halt. The build is halted by sending a Kill signal and noticing
that the cancellation channel is closed.
This first pass implementation does not allow cancellation during a
pull, but that will come in a subsequent PR.
* Add documentation of cancellation to cli and API
* Protect job cancellation with sync.Once
* Add TestBuildCancelationKillsSleep
* Add test case for build cancellation of RUN statements.

`TestBuildSpaces` is used to do string manipulation to redact timestamps
from compared cmd output. However it was assuming there is going to be
only one `time=".."` in the output --not the case on windows. Therefore
I wrote a regexp to redact all log timestamps.
Also the test used to have a copy/paste bug (see err1/err2). This fixes
that, too.

With this Dockerfile
```
FROM ubuntu
ENV ABC=""
VOLUME $ABC
```
It builds ok but then at run time I get this error:
FATA[0002] Error response from daemon: Cannot start container 8902b4a7aaf5c4e4b11a38070d392db465fa97ad88c91c8b38dda5ab8149ccac: [8] System error: no such file or directory
Because the Volume config shows "" as the path. This PR checks for "" as
the path and stops it at build time.

When the deamon starts up with log level set to INFO it will show something
like this:
```
INFO[0000] Loading containers: start.
................................................................
INFO[0000] Loading containers: done.
```
where the dots represent containers in the system.
When you run with log level set to "error" it will still show the dots
w/o the "Loading..." lines before and after which looks really odd.
This PR will fix it so that the dots are only shown IFF the "Loading..."
lines are also shown

Currently the daemon will not stop on error because the serve API job is
blocking the channel wait for daemon init. A better way is to run the
blocking serve API job as a goroutine and make sure that error
notification gets back to the main daemon thread (using the already
existing channel) so that clean shutdown can occur on error.

This modifies iptables.Exists so that it must be called with an explicit
table and chain. This allows us (a) to generate an appropriate command
line for "iptables -C", which was not previously possible, and (b) it
allows us to limit our strings.Contains() search to just the table and
chain in question, preventing erroneous matches against unrelated rules.

Save "LABEL" field in Dockerfile into image content.
This will allow a user to save user data into an image, which
can later be retrieved using:
docker inspect IMAGEID
I have copied this from the "Comment" handling in docker images.
We want to be able to add Name/Value data to an image to describe the image,
and then be able to use other tools to look at this data, to be able to do
security checks based on this data.
We are thinking about adding version names,
Perhaps listing the content of the dockerfile.
Descriptions of where the code came from etc.
This LABEL field should also be allowed to be specified in the
docker import --change LABEL:Name=Value
docker commit --change LABEL:Name=Value
