[libvirt] [libvirt PATCH v2] Introduce virDomainChrDefNew()

Make: passed Make check: passed Make syntax-check: passed Hi, this is the commit to introduce the function to create new character device definition for the domain as advised by Cole Robinson <crobinso(a)redhat.com&gt;. The function is used on the relevant places and also new tests has been added.
