Merge xpp rev. 3495:

------------------------------------------------------------------------
r2243 | tzafrir | 2007-02-28 02:05:59 +0200 (Wed, 28 Feb 2007) | 4 lines

* xpp rev. 3495: fix a race in the FXO driver of recent weeks.
* Add the Astribank BRI driver (though still needs bristuffed zaptel
  to build and thus will not build by default)

------------------------------------------------------------------------

Xorcom rev. 3491:
 * Version of xpp modules is set from xpp/.version, rather than "unknown".
 * Astribank devices are now initialized in parallel: faster startup
   when there are multiple Astribanks.
 * Re-added support for the old format of /proc/xpp/sync write:
   (echo N 0 > /proc/xpp/sync ) . The new format (SYNC=NN) is preffered.
 * Firmware update to fix a PCM issue.
 * Fixed a build issue with kernel 2.6.8 .
 * Fixed missing initialization in Zaptel::Xpp::Xbus .
 * genzaptelconf will now set FXS ports as LS by default. To set them as 
   KS, use fxs_default_start=ks in /etc/default/zaptel / /etc/sysconfig/zaptel
   (Also a workaround for #7755 ).
 * Groundwork for sync from zaptel master span: if zaptel is built with
   ZAPTEL_SYNC_TIC (see zaptel/team/tzafrir/sync ), xpp will report its 
   drift from the zaptel sync master.
 * USB firmware update: had bad lines checksums (and fxload did not report).
 * fpga_load can now better report bad hex file checksum ;-) .

Add the Zaptel and Zaptel::Xpp perl modules, and some simple 
utilities that use them. disabled by default for now.
