xpp.r5254:

* Improved polarity reversal hangups in FXO (r5194).
  Fixed false detection of polarity reversals.
* Optimize xframe allocation, by not zeroing the whole
  memory (in get_xframe()).
* Fixed erronous error message that appeared sometimes
  from fpga_load during USB renumeration.
* Zaptel::Chans now provides battery() reporting for some FXO
  channels (Astribank FXO and wcfxo).
