* Merge from Debian. Remaining changes: - debian/control: Depend on (dahdi-dkms | dahdi-source) and gawk * Dropped changes: - debian/dahdi.postinst: Upstream init script does not fail if no dahdi modules are present, so no use for the error handler in the postinst file. - debian/rules: For the same reason no need to set an error handler in the rules file.
