Misc tweaks to node device impl
* src/libvirt.c: Log registration of new node device driver impls
* src/node_device_conf.h, src/node_device.c: Merge block capability
into storage. Print vendor/product IDs in hex
* src/node_device_devkit.c: Change block to storage
* src/node_device_hal.c: Merge block cap into storage. Skip
devices without any capabilities listed
* src/virsh.c: Sort device list alphabetically
