xpp: a massive backport from DAHDI. From Xorcom branch-rel-6839-r6908 .

Sun Mar  1 2009 Oron Peled <oron@actcom.co.il> - xpp.r6795
  * Fix cases where the command_queue overflowed during initialization.
    - Also add a 'command_queue_length' parameter to xpp.ko
  * More migrations to sysfs:
    - Add a 'transport' attribute to our astribank devices which
      points to the usb device we use. E.g:
       /sys/bus/astribanks/devices/xbus-00/transport is symlinked to
       ../../../../../../devices/pci0000:00/0000:00:10.4/usb5/5-4
    - Move /proc/xpp/XBUS-??/XPD-??/span to
      /sys/bus/xpds/devices/??:?:?/span
    - Migrate from /proc/xpp/sync to:
      /sys/bus/astribanks/drivers/xppdrv/sync
    - New 'offhook' attribute in:
      /sys/bus/xpds/devices/??:?:?/offhook
  * PRI: change the "timing" priority to match the convention used by
         other PRI cards -- I.e: lower numbers (not 0) have higher
	 priority.
  * FXO: 
    - Power denial: create two module parameters instead of hard-coded
      constants (power_denial_safezone, power_denial_minlen).
      For sites that get non-standard power-denial signals from central
      office on offhook.
    - Don't hangup on power-denial, just notify Dahdi and wait for
    - Fix caller-id detection for the case central office sends it before
      first ring without any indication before.
      Asterisk's desicion.
Mon, Dec  8 2008 Oron Peled <oron@actcom.co.il> - xpp.r6430
  * PRI:
    - Match our span clocking priorities (in system.conf)
      to Digium -- this is a reversal of the previous state.
      Now lower numbers (greater than 0) are better.
    - Synchronization fixes for PRI ports other than 0.
    - Fix T1 CRC for some countries (e.g: China).
  * FXS: fix bug in VMWI detection if using old asterisk
    which does not provide ZT_VMWI ioctl().
  * FXO:
    - Improve caller_id_style module parameter. This provide a workaround
      for countries that send this information without any notification
      (reverse polarity, ring, etc.)
    - Don't force on-hook upon power-denial. So, loopstart devices
      would ignore these as expected.
  * Implement a flow-control to prevent user space (init_card_* scripts)
    from pressuring our command queue.
