6a140ec by Guy Harris (guy@xxxxxxxxxxxx):
Fix packet length handling.
Treat the packet length as unsigned - it shouldn't be negative in the
file. If it is, that'll probably cause the sscanf to fail, so we'll
report the file as bad.
Check it against WTAP_MAX_PACKET_SIZE to make sure we don't try to
allocate a huge amount of memory, just as we do in other file readers.
Use the now-validated packet size as the length in
ws_buffer_assure_space(), so we are certain to have enough space, and
don't allocate too much space.
Merge the header and packet data parsing routines while we're at it.
