Autonomous generators must be genuinely autonomous (having their own

starting the retry timer immediately.

Add reference-counting to processes.

Add timer_running() test.

Achieved via Perl using:

perl -pi -e 's/pk_buff/io_buffer/g; s/Packet buffer/I\/O buffer/ig; ' \

connections might break things. Only-sending applications like syslog()
do not need a newdata() handler, so added a check if that handler exists.

ISA 3c509 is currently non-functional, although the EISA (3c509-eisa) and
MCA (3c529) variants should build OK.

None of this code is yet tested.
