This is a monster checkin that really should have been done a lot before,
...
but many of the changes are dependent on each other. This checkin is an
intermediate version that is not complete and may not even compile, but I
don't dare sit on the changes any longer.
One of the major changes is the API for the state machine system which
has been changed a lot to facilitate some new features. The most obvious
result of this is that some of the code in G3/fsm.c now needs to be
modified. I hope this is a good change, although the syntax is
doubious as it makes heavy use of the C preprocessor and the state
machine functions really don't look like C functions any more.
Another important change is the HAL, which should make it easier to
make this code work on non-ISDN hardware.
Take care; much work remains.
