There is some issue on binding raw ICMPv6 socket immediately after assigning address on 3.14 (and probably later) kernel.
This causes ipv6_nd to fail to start.
This patch makes ipv6_nd to try to bind later if bind fails.

* fixed various bugs
* introduced accel-cmd program
* ippool: impelented persistance
* radius: implemented default-realm option

* shaper: implemented mtu option
* net-snmp: fixed run out of FD_SETSIZE

Use unshare(CLONE_FILES) to create a local file descriptors namespace
for the SNMP thread. This is similar to what was done in bf5340
'net-snmp: run snmp in "special" thread', but without calling clone()
directly. So the net-snmp plugin keeps running in a regular pthread.

snmp_thread() needs to be run as regular thread to allow Valgrind
analysis. Using a different namespace for file desciptors will be
done later on using unshare().

NET-SNMP is built on top of stale file descriptor multiplexing mechanism (select)
which prevents to use descriptors with number >= 1024.
Due to accel-ppp uses a lots of descriptors NET-SNMP easy overflows this limit and fails
and even may crash whole accel-ppp process.
This patch runs snmp in special thread which does not share file descritor table
with main process, so it can use less descriptors and live in __FD_SETSIZE limit.

triton: do not call context close if it is marked as need free (f.e. context already called triton_context_unregister)

The triton_terminate() function works by setting the need_close flag
of each triton context, then queues this context for execution by a
triton thread if not already running. But if the context is already
being run by a triton thread, it may not notice that its need_close
flag has been updated (this flag is only checked at the beginning
of ctx_thread()). So if no other event wakes up that context (i.e.
if ctx_thread() isn't run again), it will never terminate.

This patch moves the need_close flag check at the end of ctx_thread()
so that a triton context can take the need_close flag into account
event if it's updated while running.

The context spinlock is also used to protect the need_close flag as
it is concurrently updated by triton_terminate().

The 'hw' parameter of cl_key_from_mac() is actually a pointer, so
'key.hw' must be used instead to compute the size of the MAC address.
