      feat: bitswap protocol extensions · b3a47bcf
      dirkmc authored 
      This commit extends the bitswap protocol with two additional wantlist properties:

* WANT_HAVE/HAVE: Instead of asking for a block, a node can specify that they
  want to know if any peers "have" the block.
* WANT_HAVE_NOT/HAVE_NOT: Instead of waiting for a timeout, a node can explicitly
  request to be told immediately if their peers don't currently have the given
  block.

Additionally, nodes now tell their peers how much data they have queued to send
them when sending messages. This allows peers to better distribute requests,
keeping all peers busy but not overloaded.

Changes in this PR are described in: https://github.com/ipfs/go-bitswap/issues/186

      engine: tag peers based on usefulness · 9d580a65
      Steven Allen authored 
      This patch tracks two usefulness metrics: short-term usefulness and long-term
usefulness. Short-term usefulness is sampled frequently and highly weights new
observations. Long-term usefulness is sampled less frequently and highly weights
on long-term trends.

In practice, we do this by keeping two EWMAs. If we see an interaction within
the sampling period, we record the score, otherwise, we record a 0. The
short-term one has a high alpha and is sampled every shortTerm period. The
long-term one has a low alpha and is sampled every longTermRatio*shortTerm
period.

To calculate the final score, we sum the short-term and long-term scores then
adjust it ±25% based on our debt ratio. Peers that have historically been more
useful to us than we are to them get the highest score.
