Previously xs_fd would be left open, which is CID 1055993 (previously
partially fixed by 3bca826aae).
Instead arrange for both success and error cases to cleanup everything
on a single exit path instead of doing partial cleanup on the success
path a few operations higher up.

After starting the xenstore domain write the basic data (domid, name
and memory values) to the xenstore. This makes the domain appear
correctly in xl list. Create a stub json object in order to make e.g.
xl list -l happy.
Add a new option to init-xenstore-domain to be able to specify the
domain's name.

Create the xenstore domain with the xenstore flag specified. This
enables us to test whether such a domain is already running before
we create it. As there ought to be only one xenstore in the system
we don't need to start another one.

init-xenstore-domain takes only positional parameters today. Change
this to a more flexible parameter syntax allowing to specify additional
options or to omit some.
Today the supported usage is:
init-xenstore-domain <xenstore-kernel> <memory_mb> <flask-label>
[<ramdisk-file>]
Modify this to:
init-xenstore-domain --kernel <xenstore-kernel>
--memory <memory_mb>
[--flask <flask-label>]
[--ramdisk <ramdisk-file>]
The flask label is made optional in order to support xenstore domains
without the need of a flask enabled hypervisor.

Move xen-init-dom0 from tools/libxl to tools/helpers, as it is just a

The program init-xenstore-domain to start a xenstore domain instead
of the xenstored daemon is built, but not installed. Change that.
Move the program to a new tools subdirectory "helpers" to be able to
use libxl in a later patch. Otherwise a dependency loop will be
created.
