xpp.r5512:

* Build:
  - Zaptel >= 1.4.9 is migrating to storing kernel stuff in zaptel/kernel/*
  -  We conditionally use old/new directory scheme:
     In xpp/Kbuild and xpp/utils/Makefile use ZAP_KERNEL variable, so it's
     not confused with ZAPTEL_DIR (which appears in zaptel/Makefile as well).
  - Fix compile warnings on 64 bit systems.
  - Compile fixes for kernel-2.6.24
* UDEV:
  - /etc/udev/rules.d/xpp.rules now uses XPP_INIT_DIR to find astribank_hook.
  - astribank_hook: Modify to do nothing. Add some documentation.
* Autoconfiguration -- zapconf:
  - Don't fail zapconf et.al. if no config file was found.
  - Skip the 'IRQ Missing:' line in /proc/zaptel/nnn for wcte1xp(?).
  - Add some newer Digium cards to our hardware inventory.
  - Partially handle cases where the /proc/zaptel strings does not contain
    info about E1/T1/J1 or NT/TE.
* Better SYNC:
  - Finer tuning of PLL (New firmware).
  - Change calculation algorithm of sync offset. It now copes better
    with the variance in USB frame reception timing.
  - Statistics:
    . The view of results was moved from /proc/xpp/XBUS-*/summary to
      a new /sys/bus/astribanks/devices/xbus-*/timing and enhanced.
    . A new xpp_timing script shows all astribanks.
    . A new write only /sys/bus/astribanks/devices/xbus-*/cls is
      used to clear statistics. Eventually, clearing of XBUS related
      statistics should be done here. One that was migrated is the
      clearing of 'PCM [TR]X:' numbers currently appearing in
      /proc/xpp/XBUS-*/summary (they should be moved too later).
  - Shorten the strings representation sync_mode ("SYNC_MODE_AB" -> "AB")
    adapted their use in printk and /proc so the text is clear.
  - Added a command line parameter xpp.disable_pll_sync to stop all
    adjustments command to AB (calculations still continue as usual).
* PRI:
  - 4 port support
  - set clocking master span via ztcfg, like other zaptel devices.
* FXO:
  - Fix false hangups in some countries (voltage fluctuations).
  - Some countries send caller-id before first ring.
    Added code to handle caller-id PCM pass through according to
    a new command line parameter (xpd_fxo.caller_id_style).
  - No longer sends an event on zt_open. See #12160 .
* Misc:
  - Adapt to zaptel-1.4.8 and above ztscan: added fields returend by
    new ZT_SPANSTAT_V2 ioctl()
  - Document sysfs and waitfor_xpds.
  - Miscelaneous optimizations and bugfixes.
  - Remove deprecated pcm_tasklet parameter. The rx_tasklet parameter has
    replaced it a long time ago.
  - Add RX_CMD counter to /proc/xpp/XBUS-*/summary
  - Unclutter some of the usb disconnect messages.
  - xpp_usb: minor preformance improvements in receive.
    Expose the number of pending receive URB's in /proc/xpp/XBUS-*/xpp_usb
