CHANGES: libsnmp: Increase the maximum SNMPv3 session receive size fr…

…om 1472 to 2**31-1 bytes

For the UDP transport this patch increases the maximum message size from 1472
to about 64 KB.

This patch adjusts a limit that was introduced by commit 6e83b3c
("respect msgMaxSize in received v3 PDUs (in the weak sense that if the
serialized response PDU is more than it, we don't send it)") # v5.7.
