When virt-clone is used without autoclone or destination file, libvirt
errors with message "ERROR missing source information for device vda".
This doesn't convey what is missing. This patch will indicate which
options to use.

introduce btrfsCloneFile() for COW copy.
This patch add support for --reflink option for virt-clone.
When specified --reflink, if src and dst images all on a btrfs
fs, we could take advantage of COW copy.
If not, error out.

since we work with python2 only, mentioning it in all shebangs make
the commands from git work even when python3 is set as default.
This also fixes one test where command being ran is 'virt-xml' through
subprocess.Popen().
While at that, add '-tt' where possible in order to make everyone use
same indentation characters.

This means if we are passed an unmanaged path, we try to create a
storage pool for the parent directory.
We skip directories like /dev where doing this might be problematic.
This makes things much friendlier to use for remote connections, and
means we can always rely on having libvirt's storage APIs to use
for format probing.
This stuff is not very helpful and a pain to maintain. Let's drop it once
and for all. We still accept the CLI options and log a warning so people
hopefully take the hint.
I'm sure the solaris support is totally broken, so just drop this
overcomplicated abstraction.
Also fix a bug where we were using usermode networking in a bunch of
places where it isn't supported.
