[Xen patchbot -3.0-testing <patchbot-3.0-testing@xxxxxxxxxxxxxxxxxxx>]

# HG changeset patch
# User emellor@xxxxxxxxxxxxxxxxxxxxxx
# Node ID 578a7cd07970be6836fcc8d58b503469e5abf0de
# Parent  1be3cb670cf22b55b7bb49f7c8aec3e16fa6e28f
Allow callers to XendClient.xend_list_domains to specify the detail flag, and
turn detail off when doing vcpu-list.  This avoids calls to xenstore just to
get the list of domains for the vcpu-list call, significantly increasing
performance of that command on loaded systems.

Closes bug #545.
