723d837d05 Snapshot format changes (#2234)
Closes #2213
Omit transaction and receipt roots from abridged block.
No longer use RLP compression.

Make ordered_trie_root generic over an iterator to save an allocation.

Breaks snapshot format backwards compatibility (with other 1.4 snapshots -- it's already been broken with 1.3).

Documentation will need updating
