Tons of updates to the Astribank (xpp) driver:

* xpd_fxo.ko (FXO span) is now operational
* Remove obsolete .inc initialization files (we use user-space init)
* Added an install target to the utils dir.
* Updated README.Astribank accordingly.
* Using RBS signalling, as caller ID did not work well otherwise.
* Better handling of USB protocol errors.
* Fixed some procfs-related races.
* per-card-module ioctls.
* fxotune support.
* opermode support (set through /etc/default/zaptel for now)
* Userspace initialization script can also read registers.
* Power calibration works (and implemented in perl)
* some fine-tuning to the regster initialization parameters.
* Leds turn on before registration and turn off after it.
