and xenconsole out of /usr/libexec/xen and into one of /usr/lib/xen/bin or /usr/lib64/xen/bin. Remove all the PATH hacking inside Xend, and rely upon the PATH being set correctly from outside. Added an auxbin module for handling the hacky stuff. Replace the few /usr/bin/python bang paths with /usr/bin/env python. Signed-off-by: Ewan Mellor <ewan@xensource.com>
