SafeFire Links 1.3 alpha

This is unrestricted free alpha based on the latest LGS code.
It is completely free. There is no plans for now to make commercial
release.

Support and futher development is going to be done in my spare time so there is
no guarantee for something. Nevertheless I'll attempt to make at least bugfixes
for reported problems. If you need some feature in which I'm not interested then
you have two options:
- sponsor it;
- write it yourself. In this case I'll provide all necessary info and sources.

It is worth to note that it is impossible for me to make a complete regression
testing so if something from old features is broken in the current drop please
don't hesitate to mail a bugreport. I'll try to fix this ASAP.

====== Known problems and limitations =======
- MAC protocol doesn't allow arbitrary logical numbers. It have to have zero
  number and can't be bound to several MAC adapters
- No special DHCP support for LAN firewall usage. SFLinks have to be restarted
  manually to take new interface address
- NETBEUI traps with sfmac. The reason is unknown
- no posibility in filter to disable/enable IP subprotocol by number
- NAT portmap doesn't allow routing of complete IP subprotocol (actual for
  PPtP and IPSec) to some host
- no way to bind REMOTE_PIPE plugin because it is not part of working plugins
  chain. A "services" slot support should be added
- some options are not documented for pl_alias
- sfcon hangs PM. Can somebody rewrite OS/2 VIO subsystem?
