udp: Make the SNMP code asynchronous
...
Do not block the application when doing a SNMP request. Work
with the results coming back from the callback. Right now a
link can only be taken down and up.

This is the easiest way to integrate net-snmp with the event loop,
every 100ms we are going to check for timeouts or incoming messages

snmp session will be also shared between multiple links on
the same hardware.

msc: Fix crash due pong timeout started from a msc reset
...
This is fixing a crash that is caused by the MTP link going
down/up and the main routines asking to send a reset to the
MSC. The sending of a reset is triggering the ping/pong
timeouts. In case there is no MSC connection we could crash.
