570006f3a2 Half of the commit for 0.9.8 as the bitmap handling has changed.
(Firstly... ommitted)

Secondly, it wasn't even _dropping_ the offending packets, in the
non-blocking case. It was just returning garbage instead.

d527834a1d Basic idea behind explicit IV is to make it unpredictable for attacker.
Until now it was xor between CBC residue and 1st block from last datagram,
or in other words still predictable.

d1acb9b44f Further change pq_compat.h to generate the flag macros PQ_64BIT_IS_INTEGER
and PQ_64BIT_IS_BIGNUM with the values 0 (for false) and 1 (for true),
depending on which is true.  Use those flags everywhere else to provide
the correct implementation for handling certain operations in q PQ_64BIT.
