5e289f9eb6 Mostly mechanical rework of libalias: 
Makes it possible to have multiple packet aliasing instances in a
single process by moving all static and global variables into an
instance structure called "struct libalias".

Redefine a new API based on s/PacketAlias/LibAlias/g

Add new "instance" argument to all functions in the new API.

Implement old API in terms of the new API.

b07fbc17e9 Add Cisco Skinny Station protocol support to libalias, natd, and ppp. 
Skinny is the protocol used by Cisco IP phones to talk to Cisco Call
Managers.  With this code, one can use a Cisco IP phone behind a FreeBSD
NAT gateway.

Currently, having the Call Manager behind the NAT gateway is not supported.
More information on enabling Skinny support in libalias, natd, and ppp
can be found in those applications' manpages.

234dfc904a A new API function PacketAliasRedirectDynamic() can be used 
to mark a fully specified static link as dynamic; i.e. make
it a one-time link.

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.

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.
