emaste 37e2725e53 Update tcpdump to 4.9.2
It contains many fixes, including bounds checking, buffer overflows (in
SLIP and bittok2str_internal), buffer over-reads, and infinite loops.

One other notable change:
  Do not use getprotobynumber() for protocol name resolution.
  Do not do any protocol name resolution if -n is specified.
