Move UserLookup functionality into a separate pkg/user submodule that implements proper parsing of /etc/passwd and /etc/group, and use that to add support for "docker run -u user:group" and for getting supplementary groups (if ":group" is not specified)

Update lxc_template.go

If networking is disabled, but then pipework is used later to add nics, the network still doesn't function. Using flags=up for empty networking fixes this.

devmapper: Rename DeviceSet.RemoveDevice to DeleteDevice

"Remove" is a bit overloaded, as it is also what deactivating a
device mapper device is called. Using "delete" is more clear here.

devmapper: add and use removeDeviceAndWait helper

This adds a function that calls the lowlevel removeDevice
and then waits for it to finish.

devmapper: Move refcounting to DeviceSet

We already have some kind of refcounting in DeviceSet, this fleshes
it out to allow it to completely subsume the refcounting in
devmapper.Driver.

This allows us to drop the double refcounting, and the locking inside
devmapper.Driver. This, in particular the locking simplification will
make it easier in the future to parallelize the device mapper.

devmapper: Use removeDeviceAndWait in DeviceSet.removeDevice()

This makes sure the device is removed just like in deactivateDevice.

devmapper: Handle EBUSY while removing

For some reason we seem to get transient EBUSY when removing
thinp devices, which prohibit removing containers. When
this happens we retry a few times which seems to fix the
issue for me.

pkg: systemd: add initial MAINTAINERS

I volunteered for pkg/systemd MAINTAINER and there were no objections
during the #docker-dev meeting. For context I wrote most of the stuff in
here and wrote the dependent calls in api.go. Plus, I actively test the
code via CoreOS.
