10:26 a.m.
This patch removes the defaultDiskDriverName from the virCaps
structure. This particular default value is used only in the qemu driver
so this patch uses the recently added callback to fill the driver name
if it's needed instead of propagating it through virCaps.

Notes:
Version 4:
- tweaked naming to comply
- v3 was already ACKed
Version 3:
- new in series
