[libvirt] [PATCH 1/3]: Cleanup the virStorageDriver structs

This patch just cleans up the virStorageDriver structs so that they use the .functionPointer = functionname syntax of gcc. This makes it much easier to grep in the code later. This patch also re-arranges the order of the function pointers in remote_internal so that it matches the definition of virStorageDriver in src/driver.h. While not strictly necessary, it does make it a little more sane when looking at it in the future. Signed-off-by: Chris Lalancette <clalance(a)redhat.com&gt;
