By default list of IP address is serial at startup.
This option shuffles initial IP list so it becomes more random.

This new option will control how to represent Called-Station-ID.
Its value maybe ifname,mac or ifname:mac.
By default mac is used to keep compatibility with old versions.
Also old option ifname-in-sid is removed from documentation, but is still supported for compatibility.

  * Set default retransmission timeout to 1 second. Since we now have
    exponential backoff, we can afford a smaller value.

  * Add the rtimeout-cap option to set the maximum value the
    retransmission timer has to respect during exponential backoff.

  * Store the maximun number of retransmissions in tunnel's structure
    (like other retransmission parameters).

  * Describe all these changes in man page and reset them to their
    default values if they're removed from configuration file before a
    reload.

This new option is pattern for naming newly created vlans.
Pattern may contain following macros:
%I - name of parent interface
%N - number of vlan
By default vlan-name=%I.%N

shaper: implemented 'rate-multiplier' option to bring values to kilobits if radius sends in different basis

radius: implemented sending Account-Request with Acct-Status-Type=Accounting-On on startup and Acct-Status-Type=Accounting-Off on shutdown

As the maximum acceptable MTU for an L2TP link may vary depending on
IP and L2TP packet headers options, it is better to make it
configurable so that an administrator can adapt it to its network
constraints.
Use the original value (1420) as default.

Disable use of ephemeral ports by default since it poses problems with
NAT and wasn't used in earlier versions of accel-ppp.

ipoe: introduced 'gw-ip-address=x.x.x.x/mask' option to use it as server address and mask if radius can assign only client address

Fix indentation of sections 'log' and 'ip-pool'.
Remove space before comma in section 'chap-secret/username-hash'.

Define option 'use-ephemeral-ports' for accel-ppp.conf. When set
to 0, this option deactivates the use of ephemeral ports. That is,
accel-ppp won't choose an arbitrary source port when replying to a
tunnel establishment request, but will use the SCCRQ's destination
port instead.

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.

* cli, tcp: Fix non-NULL terminated string reception
* Fix va_end() missing calls

* auth_pap: make messages like other auth modules
* cli: check xmit_buf is not null at enter to write function
* pppoe: implemented regular expression support
* chap-secrets: implemented encryption
* ippool: fixed initialization order
* optional shaper compiling
* ppp: dns/wins code cleanup

     If enabled accel-pppd will not destroy interface immediately after corresponding session is terminated, instead interface will be brought down  and placed to cache for later use for new sessions.
     It should reduce kernel interface creation/deletion rate lack and increase responsibility of daemon
