79ec1c507a Add an integer field to keep protocol-specific flags with links.
For FTP control connection, keep the CRLF end-of-line termination
status in there.

Fixed the bug when the first FTP command in a session was ignored.

03453c5e87 A significant rewrite of PPTP aliasing code.
PPTP links are no longer dropped by simple (and inappropriate in this
case) "inactivity timeout" procedure, only when requested through the
control connection.

It is now possible to have multiple PPTP servers running behind NAT.
Just redirect the incoming TCP traffic to port 1723, everything else
is done transparently.

Problems were reported and the fix was tested by:
		Michael Adler <Michael.Adler@compaq.com>,
		David Andersen <dga@lcs.mit.edu>

55a39fc5a2 Added true support for PPTP aliasing. Some nice features include:
- Multiple PPTP clients behind NAT to the same or different servers.

- Single PPTP server behind NAT -- you just need to redirect TCP
  port 1723 to a local machine.  Multiple servers behind NAT is
  possible but would require a simple API change.

- No API changes!

For more information on how this works see comments at the start of
the alias_pptp.c.

PacketAliasPptp() is no longer necessary and will be removed soon.

7652512976 - Added support for passive mode FTP by aliasing 227 replies.
It does mean that it is now possible to run passive-mode FTP
  server behind NAT.

- SECURITY: FTP aliasing engine now ensures that:
  o the segment preceding a PORT/227 segment terminates with a \r\n;
  o the IP address in the PORT/227 matches the source IP address of
    the packet;
  o the port number in the PORT command or 277 reply is greater than
    or equal to 1024.

8060760500 Replace PacketAliasRedirectPptp() (which had nothing specific
to PPTP) with more generic PacketAliasRedirectProto().

Major number is not bumped because it is believed that noone
has started using PacketAliasRedirectPptp() yet.

Add bounds checking to netbios NS packet resolving code.  This should
    prevent natd from crashing on badly formed netbios packets (as might be
    heard when the machine is sitting on a cable modem or certain DSL
    networks), and also closes potential security holes that might have
    exploited the lack of bounds checking in the previous version of the
    code.

3b160b8b6e Create the alias library. This is currently only used by
ppp (or will be shortly).  Natd can now be updated to use
this library rather than carrying its own version of the code.
