src/conf/node_device_conf.h:
* New macro VIR_CONNECT_LIST_NODE_DEVICES_FILTERS_CAP
* Declare virNodeDeviceList
src/conf/node_device_conf.c:
* New helpers virNodeDeviceCapMatch, virNodeDeviceMatch.
virNodeDeviceCapMatch looks up the list of all the caps the device
support, to see if the device support the cap type.
* Implement virNodeDeviceList
src/libvirt_private.syms:
* Export virNodeDeviceList
* Export virNodeDevCapTypeFromString
