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.

This removes `bash` dependency from save/load integration tests.
It used to call `/bin/bash -c 'c:\...\docker.exe'` which is not valid.
Also removed usage of tempdirs and temp files for saving/loading
repos. All are now done using in-memory pipes and buffers.
Created `runCommandPipelineWithOutput` helper to replace the
`/bin/bash -c 'a | b | c'` using pipes and returning output from
last command in the pipeline. This makes the code even shorter
and readable.

Some tests in `docker_api_containers_test.go` assume the
docker daemon is running at the same machine as the cli
and uses `ioutil.TempDir` to create temp dirs and use them
in the test.
On windows ioutil.TempDir and os.TempDir would create win-style
paths and pass them to daemon. Instead, I hardcoded `/tmp/` and
generate some random path manually and allow daemon to create
the directory.
Fixes tests:
- TestContainerApiStartVolumeBinds
- TestContainerApiStartDupVolumeBinds
- TestVolumesFromHasPriority
Downside:
- Does not clean the temp dirs generated on the remote daemon
machine unless delete container deletes them.

TestEventsUntag requires a `timeout` command which does not
exist on OS X or Windows (in fact, windows has a totally different
timeout program and this test was accidentally using it).
- Created runCommandWithOutputForDuration.
This entirely replaces runDockerCommandWithTimeout and
removes dependency to `timeout` command.
- Made runDockerCommandWithTimeout reuse runDockerCommandForDuration.
TestEventsUntag works now on Windows.

Current uses of `makeRandomString` is to create really
long strings. In #10794, I used them to create nearly-unique
unix paths for the daemon. Although collions are harmless and
don't fail the tests, this prevents the same strings from being
created consistently in every run by seeding rand.Random.
