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.

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.

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.
