The [gelf payload specification](http://docs.graylog.org/en/2.4/pages/gelf.html#gelf-payload-specification)
demands that the field `short_message` *MUST* be set by the client library.
Since docker logging via the gelf driver sends messages line by line, it can happen that messages with an empty
`short_message` are passed on. This causes strict downstream processors (like graylog) to raise an exception.
The logger now skips messages with an empty line.

Now that we do check if overlay is working by performing an actual
overlayfs mount, there's no need in extra checks for the kernel version
or the filesystem type. Actual mount check is sufficient.

Before this commit, overlay check was performed by looking for
`overlay` in /proc/filesystem. This obviously might not work
for rootless Docker (fs is there, but one can't use it as non-root).
This commit changes the check to perform the actual mount, by reusing
the code previously written to check for multiple lower dirs support.
The old check is removed from both drivers, as well as the additional
check for the multiple lower dirs support in overlay2 since it's now
a part of the main check.

This moves supportsMultipleLowerDir() to overlayutils
so it can be used from both overlay and overlay2.
The only changes made were:
* replace logger with logrus
* don't use workDirName mergedDirName constants
* add mnt var to improve readability a bit
This is a preparation for the next commit.

This fix tries to address the issue raised in 39353 where
docker crash when creating namespaces with UID in /etc/subuid and /etc/subgid.
The issue was that, mapping to `/etc/sub[u,g]id` in docker does not
allow numeric ID.
This fix fixes the issue by probing other combinations (uid:groupname, username:gid, uid:gid)
when normal username:groupname fails.
This fix fixes 39353.

As described in https://golang.org/s/generatedcode, Go has
a formalized format that should be used to indicate that a
file is generated.
Matching that format helps linters to skip generated files;
From https://golang.org/s/generatedcode (https://github.com/golang/go/issues/13560#issuecomment-288457920);
> Generated files are marked by a line of text that matches the regular expression, in Go syntax:
>
> ^// Code generated .* DO NOT EDIT\.$
>
> The `.*` means the tool can put whatever folderol it wants in there, but the comment
> must be a single line and must start with `Code generated` and end with `DO NOT EDIT.`,
> with a period.
>
> The text may appear anywhere in the file.
This patch updates the autogenerated code to match that format.

This patch updates the template used for our generated types
to match that format.
