Allow parallel 32- and 64-bit Xen installations. Move xc_save, xc_restore,

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.
