l2tp: Full hidden AVPs support
Add option "hide-avps" in the "l2tp" section for hiding attributes
sent to peer. This same option is also made available on accel-ppp's
command line interface:
accel-ppp# tunnel create tunnel peer-addr 192.0.2.1 hide-avps 1
Attribute hiding is performed upon attribute creation (in the
l2tp_packet_add_*() functions family) rather than upon packet sending.
This avoid running the cipher for every retransmission; the counterpart
is that l2tp_packet_print() can't dump original attributes of hidden
AVPs.
Currently, only one random vector is used for all hidden AVPs in a
packet. This is easily extensible though, as the 'last_RV' field in
struct l2tp_packet_t may be overridden to use new vectors for next
AVPs.
