lib: Replace shim IPCPs with points of attachment
Removes the UDP and Ethernet shim IPCPs. The unicast and broadcast
IPCPs can now directly attach to a "legacy" socket. We adopt Saltzer's
Point-of-Attachment terminology, also advocated in Day's "Patterns in
Network Architecture". The "poa" component manages these
PoA's with one management thread, one link monitoring thread and one
thread per attached point.
For Ethernet PoA's the irm connect and enroll can resolve the
destination IPCP or Layer name with a broadcast name query over the
attached PoAs (first reply wins). UDP PoA's require a destination IP
address or FQDN.
attach to a local endpoint (required both server and client side):
irm ipcp poa attach name a udp 10.0.0.1
irm ipcp poa attach name a udp 10.0.0.1:3435
irm ipcp poa attach name a udp [::1]:3435
irm ipcp poa attach name a eth dev eth0
irm ipcp poa attach name a eth dev eth0 ethertype 0xA000
release a PoA (refused while it carries a flow):
irm ipcp poa detach name a udp 10.0.0.1:3435
irm ipcp poa detach name a eth eth0
list an IPCP's PoAs:
irm ipcp poa list name a
connect to a peer, by name or at an address:
irm ipcp connect name b dst a
irm ipcp connect name b dst a eth
irm ipcp connect name b dst a eth dev eth0
irm ipcp connect name b dst a udp 10.0.0.1:3435
irm ipcp connect name b dst a udp peer.example.com:3435
disconnect by peer name, no address:
irm ipcp disconnect name b dst a
irm ipcp disconnect name b dst a component mgmt
enroll has the same shape as connect:
irm ipcp enroll name b layer lr autobind
irm ipcp enroll name b layer lr autobind eth dev eth0
irm ipcp enroll name b layer lr autobind udp 10.0.0.1:3435
the IRMd config file attaches PoAs and names peers the same way:
udp = [ "10.0.0.1", "10.0.0.1:3436" ]
eth = [ "eth0", {dev="eth1", ethertype=0xA007} ]
enrol={dst="LAN", eth={dev="eth0"}}
conn=[{dst="lan3", eth={}}, {dst="lan4", udp="10.0.0.1:3435"}]
