Subject: dahdi-perl fixes, mostly xpp-specific.

* Fix pattern for PCI BRI cards
* Fix recognizing xpp devices by @connector in xpp_order
* Print more helpful comments in xpp_order
* Remove most (if not all) need of /proc/bus/usb
* Handle other similar "is_twinstar" errors.

  dahdi_genconf: xpp_order generator: Extra '#' after connector comment

  Add an extra '#' right after the connector string to make it simpler
  to use the connector string from the generated xpp_order.

  xpp: make /proc/bus/usb/devices optional

  Get the information we read from /proc/bus/usb/devices from
  /sys/bus/usb/devices . Tested on my Debian Unstable with 2.6.30 kernel.

  The default is still /proc/bus/usb and sysfs is only used if the procfs
  file is not found.

  Also fixes a case of using the sysfs attribute busnum, that does not
  exist in kernel 2.6.9 . Devise the bus number from the name of the node.

  dahdi-perl: Avoid '"is_twinstar" on unblessed reference'

  Dpn't panic if a device is not found in the list of hardware. This
  is not only indication of a bug, but can also happen if a device
  appeared after the script was started.
