Log:
xpp.r6616: More sysfs, FXO enhancements, BRI fixes

* Fix cases where the command_queue overflowed during initialization.
* 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
* 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.

From: trunk r5663 (mainly), r5688, r5708 (minor fixes)
