The libvirt backend currently doesn't support direct mode. We should
make that work in future. As a workaround, force the attach-method to
be 'appliance' in this case.

We set the error handler to NULL in order to mask "normal" error
messages that we expect to see because of the unusual way that
virt-rescue runs the appliance. However if the user selected -v /
enabled debugging, then it is reasonable to expect they want to see
every message, so do not mask anything.

The new API splits orderly close into a two-step process:
if (guestfs_shutdown (g) == -1) {
/* handle the error, eg. qemu error */
}
guestfs_close (g);
Note that the explicit shutdown step is only necessary in the case
where you have made changes to the disk image and want to handle write
errors. Read the documentation for further information.
This change also:
- deprecates guestfs_kill_subprocess
- turns guestfs_kill_subprocess into the same as guestfs_shutdown
- changes guestfish and other tools to call shutdown + close
where necessary (not for read-only tools)
- updates documentation
- updates examples

This lets you create temporary scratch disks.

Ensure that the drv structure is always zeroed on allocation.
Don't leak old drv->device when add_drives is called multiple times.

These calls allow you to change the number of virtual CPUs assigned to
the appliance.
This also adds a --smp option to virt-rescue.

errno is pretty much random on the error path back from guestfs_launch
so there is nothing useful to be gained by checking it.
We could do with a better way to detect if appliance launch failed.

We expect guestfs_launch to fail in this program.

This allows the default for --ro or --rw to be controlled for the
three tools guestfish, guestmount and virt-rescue.

Fix required by gcc 4.6.0.

The other programs have the variable, but the flag is not enabled
either because it doesn't make sense or because the implications are
not well understood.

(Revealed by compiling under Debian where this is a warning).
