Add unit test for virt._gen_vol_xml()
Whitespace.
Refactor virt._gen_vol_xml() to use jinja templating
Use assertEqual, less to type
assertEqual gives relevant information on fail
Remove redundant code block

The same code block is present a few lines above. Merge slip?
Make unit tests verify the disk entries in virt._gen_xml()
Refactor _gen_xml(), passes unit tests
Refactor interface (nic) part of _gen_xml()

Integrate the interfaces sections of the XML (from interface.jinja) into
the single libvirt domain XML (libvirt_domain.jinja) to provide a full
view without placeholders containing XML.
Add unit test for tcp/telnet console
Refactor serial/console part of _gen_xml()

Integrate the serial and console sections of the XML (from
serial_port_*.jinja) into the single libvirt domain
XML (libvirt_domain.jinja) to provide a full view without placeholders
containing XML.
Fix logic regarding telnet console and port

Provide a (temporary) default. Previously it was possible to skip
specifying telnet_port and it would result in a incomplete XML.
Add unit test for boot device
Refactor boot device part of _gen_xml()

The implementation that this commit replaces was carried over from my
first WIP implementation and did not fully work.

If I understand the original code correctly there was a bug in
supporting multiple boot devices because of a missing str.split().
Add unit test for disk controller
Refactor disk controller part of _gen_xml()
Add another unit test for disk controller
Use same unit as input
Skip sls refs that have already been loaded while evaluating the

Move dict repacking function to salt.utils

This allows the same repacking that is used in package management to be
used for lists of key/value pairs passed to ports.installed states.
