bmt is a new package that provides hashers for binary merkle tree hashes on
size-limited chunks. the main motivation is that using BMT hash as the chunk
hash of the swarm hash offers logsize inclusion proofs for arbitrary files on a
32-byte resolution completely viable to use in challenges on the blockchain.

Using a Timer over Ticker seems to be a lot better, though I cannot fully
account for why that it behaves so (since Ticker should be more bursty, but not
necessarily more active over time, but that may depend on how long window it
uses to decide on when to tick next)

core/vm: more benchmarks

core/types: encode receipt status in PostState field

This fixes a regression where the new Failed field in ReceiptForStorage
rejected previously stored receipts. Fix it by removing the new field
and store status in the PostState field. This also removes massive RLP
hackery around the status field.
