Add comments telling people not to gratuitously change the capture file

format (file header or per-packet header format, or interpretation of
any of the fields in those headers) without getting a new magic number
from "tcpdump-workers@tcpdump.org", and to make sure that libpcap can
still read files with the existing magic numbers, not just files with
the new magic number and record formats.

(There have been at least three libpcap changes I know of that have
changed the header formats, or the interpretation of fields in those
headers, without changing the magic number.  I would like not to ever
have any other such changes happen ever again.)
