ISDN Voice Box Answering Machine

This release has time-based configuration, better compatibility with Python 2.2, and many bugfixes.

Compatibility with gcc 2.95 and script argument parsing fixes.

This is a complete rewrite. A daemon architecture
is used instead of a getty architecture. Call
disptaching was made more flexible. Multiple
channels per daemon and multiple telephony
applications per daemon are now supported. The
default voice box application is now more
powerful.

This release has compilation fixes, and has been updated for libshbuf 0.0.3.

Better latency (thus reacts quicker on touchtone sequences), syslog support, passing the incoming telephone number to the processing script (and thus mailed to the user), better documentation, and assorted fixes.
