This fix tries to address the issue raised in #22420. When
`--tmpfs` is specified with `/tmp`, the default value is
`rw,nosuid,nodev,noexec,relatime,size=65536k`. When `--tmpfs`
is specified with `/tmp:rw`, then the value changed to
`rw,nosuid,nodev,noexec,relatime`.
The reason for such an inconsistency is because docker tries
to add `size=65536k` option only when user provides no option.
This fix tries to address this issue by always pre-progating
`size=65536k` along with `rw,nosuid,nodev,noexec,relatime`.
If user provides a different value (e.g., `size=8192k`), it
will override the `size=65536k` anyway since the combined
options will be parsed and merged to remove any duplicates.
Additional test cases have been added to cover the changes
in this fix.
This fix fixes#22420.

For me when I run the test I see:
```
Downloading from http://nourl/bad
Importing 283 B
Untar re-exec error: exit status 1: output: unexpected EOF
```
and nothing about "dial tcp" so it appears that the output is
system dependent and therefore we can't really check it. I think
checking for non-zero exit code is sufficient so I'm removing this
string check.

Using golang 1.6, is it now possible to ignore SIGPIPE events on
stdout/stderr. Previous versions of the golang library cached 10
events and then killed the process receiving the events.
systemd-journald sends SIGPIPE events when jounald is restarted and
the target of the unit file writes to stdout/stderr. Docker logs to stdout/stderr.
This patch silently ignores all SIGPIPE events.

The path we're trying to remove doesn't exist after a successful
chroot+chdir because a / is only appended after pivot_root is
successful and so we can't cleanup anymore with the old path.
Also fix leaking .pivot_root dirs under /var/lib/docker/tmp/docker-builder*
on error.

The jsonlog logger currently allows specifying envs and labels that
should be propagated to the log message, however there has been no way
to read that back.
This adds a new API option to enable inserting these attrs back to the
log reader.
With timestamps, this looks like so:
```
92016-04-08T15:28:09.835913720Z foo=bar,hello=world hello
```
The extra attrs are comma separated before the log message but after
timestamps.
Without timestaps it looks like so:
```
foo=bar,hello=world hello
```

This fixes one issue with Docker running under a grsec kernel, which
denies chmod and mknod under chroot.
Note, if pivot_root fails it will still fallback to chroot.

pidfile.New() was opening a file in /proc to determine if the owning
process still exists. Use syscall.OpenProcess() on Windows instead.
Other OSes may also need to be updated here.
