Use base constructors for unpackers.
Remove trailing whitespace.
Don't store collections in the unpackers.
Move to a central management of unpackers.

Unpackers are created via a central management module in terms of (FED ID,
AMC ID, block ID, FW ID).  This module now also registers the products with
the EDM framework and creates collection objects.
Get unpackers for a set of FED, AMC, FW ids.

These free ids fix a set of block ↔ unpacker associations, which are needed
for every AMC block.
