[ocaml-platform] Pcap-related packages in OPAM

[David Scott]

Hi,

OK, I think the convention that a library which understands the format
"foo" is called "foo-format" is fine. Thanks for the reminder about the
ocamlfind package name too. I've updated two packages (and ocamlfind names):

  pcap-format
  vhd-format

(Note there still may be a clash between the module names defined in these
ocamlfind packages and other similar ones making it hard to compile them
into the same program -- I guess namespaces will help with this eventually)

The pcap-format package update pull request is pending review[1] while the
vhd-format package has already been merged into OCamlPro/opam-repository on
github.

Cheers,
Dave
