This changes add_to_pktbuf() to maintain a pointer to the last entry
in the list, avoiding a linear walk-through on each call.  Before this
change, add_to_pktbuf() could take a significant amount of time (10%
of total decoding time), even with input files of several minutes.
After the change, the time spent in this function is barely measurable
with oprofile.

have already been caught in the previous ifs. Also the
condition b == 0x1000 could never be true (it would
triggered the return).
