838d9af2c8 Properly handle the case when either the aliasing or source address of
the link are equal to the default aliasing address.  Do not zero them!

This will fix the problem with non-working links added with the source
and/or aliasing address equal to the default aliasing address, but the
default aliasing address is set later, after the link has been set up,
like both natd(8) and ppp(8) do (for objective reasons).

bd3ed4542d ReLink() partial links in FindLinkOut() in the same manner as we do it
in FindLinkIn().  This will make TcpMonitorIn()/TcpMonitorOut() happy.

f3baa77e5e Restore previous version of FindLinkIn().
Instead, natd(8) should be fixed to call PacketAliasSetAddress()
as part of initialization, as required by libalias(3).

02136bf8b0 - Make partially specified permanent links (without `dst_addr' and/or
`dst_port') work for outgoing packets.

- Make permanent links whose `alias_addr' matches the primary aliasing
  address `aliasAddress' work for incoming packets.

- Typo fixes.

29d958bb8a Handle TCP reset sequence properly.
In the words of originator:
:If an incoming connection is initiated through natd and deny_incoming is
:not set, then a new alias_link structure is created to handle the link.
:If there is nothing listening for the incoming connection, then the kernel
:responds with a RST for the connection. However, this is not processed
:correctly in libalias/alias.c:TcpMonitor{In,Out} and
:libalias/alias_db.c:SetState{In,Out} as it thinks a connection
:has been established and therefore applies a timeout of 86400 seconds
:to the link.
:
:If many of these half-connections are initiated (during, for example, a
:port scan of the host), then many thousands of unnecessary links are
:created and the resident size of natd balloons to 20MB or more.

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.

0ffaca1078 1) in CleanupAliasData, don't nullify entry in linkTableOut
since there might be permanent entries still left after
   calls to DeleteLink (it will be nullified by DeleteLink
   if all entries are deleted, won't it ?)

2) in PacketAliasSetAddress, set the aliasing address
   even when PKT_ALIAS_RESET_ON_ADDR_CHANGE is in effect.
   Just don't clean up links in this case.
