[libvirt] [PATCH v2 0/2] Need to perform address checks for ccw/s390

Assumptions were made that if someone provided an address type ccw or s390 that it would occur only if using an enabled emulator. Turns out that premise isn't necessarily true and it leads to libvirtd crashing for hotplugs and qemu start errors for config paths. These patches will make the checks prior to crashes or qemu process starts in order to avoid the situation. v1: http://www.redhat.com/archives/libvir-list/2015-August/msg01043.html Changes since v1... ... Implement a function to handle the s390-ccw check using STRPREFIX instead of a mix of STRPREFIX and STREQLEN ... Create qemuCheckCCWS390AddressSupport to handle checking address type if defined on entry to disk, controller, and rng device additions whether through hotplug or config options. NB: It doesn't seem network devices are afflicted, although perhaps I read the code wrong. It seems for a network device there is/was none of the set the default address if undefined code added.
