* ipoe: assign point-to-point addresses to non-shared physical interface (prevents route cleaning by interface renaming)
* ipoe: lua: add "vlan" field to session object
* ipoe: fixed prefix calculation from ipaddr
* ipoe: implemented ability to change ipset by CoA
* ipoe: included lua bitop library
* ipoe: implemented support for vendor specific attrbiutes
* ipoe: add client ip as route when nat=1
* shaper: fixed conditions to install limiter (may install only up or only down limiter)
* shaper: fixed bug in class id allocation procedure
* cmake: check for pcre and openssl headers are present
* implemented session count limiting
* support for openssl-1.1
* fixed connection problem with clients having nomru option

Fixed problem while connecting with clients in which mru not
negotiating lcp option is set

introduced new config option:
[ipoe]
vendor=Name

this affects to all attributes specified in attr-xxx options

new config option:
[common]
max-sessions=N

If set then accel-pppd stops reply to new connection requests if total number of sessions (active and starting) is reached specified limit.

This reverts commit e3fc927e.

this is related only for htb

new config option:
[common]
max-sessions=N

If set then accel-pppd stops reply to new connection requests if total number of sessions (active and starting) is reached specified limit.

Included bitop library http://bitop.luajit.org/index.html
It may be used to extract vlan components in username function:
function username(ses)
  vid=ses:vlan()
  svid=bit.rshift(vid,16)
  cvid=bit.band(vid,0xffff)
  ...
end

For this need to send 2 attributes: L4-Redirect=1,L4-Redirect-Ipset=new-set

This reverts commit 51592769.

resulting value is vlan | (parent_vlan << 16)

radius: introduced radius_plugin_t:send_accounting_update function (called each time when accounting interim update is about to send)

ipoe: assign point-to-point addresses to non-shared physical interface (prevents route cleaning by interface renaming)

* general rewrite and improve ipoe/vlan_mon drivers
* ipoe: generate EUI-64 interface identifier for ipv6 addresses
* ipoe: log warning if interface was not started by vlan_mon notification
* ipoe: introduced option "start=auto"
* ipoe: translate UP session to dhcp session when dhcp request received (for shared=0 interfaces)
* ipoe: implemented starting UP session by arp request
* ipoe: log interface renaming
* pppoe: add interface name to log messages
* pppoe: implemented vlan_mon support
* pppd_compat: change mode of radattr files to 0644
* pppd_compat: check for script existance before fork
* radius: implemented handling of Framed-Route attribute
* radius: do not send NAS-Port and NAS-Port-Id if they are undefined
* radius: add Delegated-IPv6-Prefix to accounting packets
* radius: update Session-Timeout by CoA
* shaper: implemented internal class id map
* ppp: introduced unit-preallocate option
* ipv6: remove ipv6 address and routes on session termination
* vlan_mon: introduced autoclean module parameter
* iprange: implement config reload
* make termination caused by SIGTERM soft
* remove pid file on exit
* for single-session=deny make early check for duplicate username (before calling radius)
* fixed broken "noauth" mode

accel-dp will be continued in separated branch

Bacause interface may not still exists in authentication phase

If set to 1 then allocate unit (interface) before authorization, so Nas-Port and Nas-Port-Id would be defined in Access-Request phase

The 'installed' bit of the allocated ipv6db_addr_t structure needs to
be initialised. This is because ap_session_ifdown() reads this bit to
know if the address or route needs to be removed from the kernel.
The 'installed' bit is set by ap_session_accounting_started() and the
ND and DHCPV6 protocol handlers, but disconnection could happen before
these steps.
