feature: pppd gigaword support & rp-pppoe Intermediate agent

[Sash]

Gigaword accounting: Stock pppd will wrap it's accounting counters around at the 4G barrier (32 bit limitation), making it unsutiable for long running sessions and where the accuracy of the accounting information is actually important. This patch gives you a 64bit counter to work with instead, eliminating this problem.

PPPoE Intermediate agent support: ADSL forum TR-101 defines an intermediate agent that inserts additional PPPoE tags into PADI/PADR frames sent from clients. These tags contain additional information such as circuit id and other information which can be used to implement credential-less logins and give you more effective control over your user sessions.
