Add radiusd_ipcp(8). A module which provides IP configuration through RADIUS Access-Accept messages and manages IP address pool through RADIUS accounting messages.
Sync EVP_MD_CTX to heap switch from npppd.
Add radiusd(8) and radiusctl(8). They are WIP. radiusd(8) is a RADIUS server and radiusctl(8) is to control the server. radiusd(8) currently supports bsdauth and radius (upstream radius servers) as authentication backends.
Add "delete" command to "radiusctl ipcp". Also, send "stop" that was missing when disconnecting all when acct-{on,off} received.
Handle radiusd and npppd, they are different but nothing stands out.
