[libvirt] [PATCH 0/9] Vol Zeroing API

This patch set contains a new API for zeroing out volumes. I called it zero out rather than overwrite because it doesn't overwrite anything in the case of sparse files. It does guarantee that any subsequent reads from the volume will return zeroes. The ESX driver change is part of the patch. Without it, the struct is missing its initializer and fails to build. I'm not sure what our position on the style of struct initializers is; there are both forms in the code. If this style is heresy, we should add a statement to that effect in HACKING.
