If a domain has no videoram (say, dom0), then treat the size as 0 and
continue, rather than just failing.

The info subcommand was missing from the xl tool. Use the new libxl
wrapper functions to create a clone of "xm info". The splitting into
several smaller functions is enspired by the implementation in
XendNode.py.

Xen provides a xen_version hypercall to query the values of several
interesting things (like hypervisor version, commandline used, actual
changeset, etc.). Create a user-friendly and efficient wrapper around
the libxc function to provide values for xl info output.
Since the information is static during the whole runtime, we store
it within the libxl_ctx structure and just deliver the pointer on
subsequent calls.

Implement "xl migrate".
ssh is used as the transport by default, although this can be
overridden by specifying a different sshcommand. This is a very
standard approach nowadays and avoids the need for daemons at the
target host in the default configuration, while providing flexibility
to admins. (In the future it might be nice to support plain
unencrypted migration over TCP, which we do not rule out now, although
it is not currently implemented.)
Properties of the migration protocol:
* The domain on the target machine is named "<domname>--incoming"
while it is being transferred.
* The domain on the source machine is renamed
"<domain>--migratedaway"
before we give the target permission to rename and unpause.
* The locking in libxl_domain_rename ensures that of two
simultaneous migration attempts no more than one will succeed.
* We go to some considerable effort to avoid leaving the domain in
a bad state if something goes wrong with one of the ends or the
network, although there is still (inevitably) a possibility of a
unresolvable state (in case of very badly timed network failure)
which is probably best resolved by destroying the domain at both
ends.
Incidental changes:
create_domain now returns a libxl error code rather than exiting on
error.
New ERROR_BADFAIL error code for reporting unpleasant failures.

* Make create_domain always return to caller
* Have create_domain set its log callback sooner
* Actually write things to logfile, and some error checking
With some combinations of options, create_domain would never return to
the caller, since it would have called daemon and will later exit. So
we fork an additional time, so that we can call daemon in the child
and also return to the caller in the parent. It's a shame that
there's no version of daemon(3) that allows us to do this without the
extra code and pointless extra fork.
daemon(0,0) closes all the fds. So we need to call daemon(0,1) and
organise detaching our stdin/out/err ourselves. Doing this makes
messages actually appear in the xl logfile in /var/log/xen.
Finally, make create_domain call libxl_ctx_set_log sooner. This makes
some lost messages appear.
