The existing Wireshark Cops PCMM dissector does not support the new I04 fields
fof PCMM. I've added the new fields which are relevant to the policy server to
the dissector. To maintain backwards copmpatiblity with I03, I check the length
of the Gate's envelope and if it doesn't match the new I04 lengths, the old
code is used.

The following ECNs for PCMM I04 are supported in this patch:
MM-N-07.0420-2
MM-N-07.0421-2
MM-N-07.0422-4
MM-N-07-0429-2
MM-N-07.0432-3

The patch has passed fuzz testing.
