handling.
When a link has a relatively high throughput, the 32-bit packet and byte counters could overflow multiple times between accounting runs.
To accommodate this limitation, directly use 64-bit interface statistics.
This also gets rid of the internal giga-word counters.

We need to include "ap_session.h" to define 'struct ap_session'.

Several modules assume that if ses->ipv6 is set, then
ses->ipv6->addr_list contains at least one element. But this is not
true if ipv6 was allocated by the pseudo ipdb backend of ipv6cp
(ipv6cp_opt_intfid.c). That is, if the PPP session only has an
automatic link-local address.
This leads modules like pppd-compat and dhcpv6 to access invalid memory
when trying to retrieve the IPv6 address of a PPP session.

to lua scripts
session object consists of following functions:
ifname() - interface name
ifindex() - interface ifindex
sid() - Acct-Session-ID
uptime() - session uptime in seconds
username()
ctrl_type() - type of session (pppt/pppoe/l2tp/ipoe)
calling_sid() - Calling-Station-ID
called_sid() - Called-Station-ID
ipv4() - retuns pair (peer address, local address)
ipv6() - ipv6 address or nil

Implemented support for lua 5.2/5.3.
To build accel-ppp with exact lua version pass it in -DLUA=x.y, for example -DLUA=5.2 (cmake 3.0 is required for this).
Old style -DLUA=TRUE supports only 5.1 and does not require cmake 3.0.
Also extra lua modules (lua_lpack, lua_bit) took out into separated library luasupp.
