The statistics were stored as allocated object for each individual
statistic and linked together via list. Store them in vector instead
which allows us to avoid a lot of small allocations and free right
after using the statistic.
The same applies to the buffered packets, use vector instead of moving
around single allocated objects. This should reduce the fragmentation.
