Swarm POC3 - happy solstice

The current trie memory database/cache that we do pruning on stores
trie nodes as binary rlp encoded blobs, and also stores the node
relationships/references for GC purposes. However, most of the trie
nodes (everything apart from a value node) is in essence just a
collection of references.

This PR switches out the RLP encoded trie blobs with the
collapsed-but-not-serialized trie nodes. This permits most of the
references to be recovered from within the node data structure,
avoiding the need to track them a second time (expensive memory wise).

remove the tail "," from genesis config,  which will cause genesis config parse error .

This package was meant to hold an improved 256 bit integer library, but
the effort was abandoned in 2015. AFAIK nothing ever used this package.
Time to say goodbye.
