      feat: move internals to an internal package · bbf65296

      This makes reading the docs much easier as it's clear what's "private" and
what's not.

      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

      fix: limit use of custom context type · 799bfb3e
      Steven Allen authored 
      Goprocess returns a _custom_ context type. Unfortunately, golang has a bunch of
magic type assertions to efficiently handle built-in context types but launches
a new goroutine when deriving a new context from a custom context type.
Otherwise, it has no way to wait on the custom context's channel.

This fix just ensures we only ever have one of goroutines per provide worker by
deriving a (normal) cancelable context up-front and then using that.

      bitswap: Bitswap now sends multiple blocks per message · eb0d1ffc
      taylor authored 
      Updated PeerRequestTask to hold multiple wantlist.Entry(s). This allows Bitswap to send multiple blocks in bulk per a Peer's request. Also, added a metric for how many blocks to put in a given message. Currently: 512 * 1024 bytes.

      bug fix: `BytesSent` in peers' ledgers now updates · bc9342bf
      dgrisham authored 
      When sending data to another user, the number of bytes sent to that user (saved
by the corresponding Bitswap ledger) was not updated (it was always 0). This
also meant that the debt ratio was also always 0.

The function that updates the `BytesSent` value in the ledger, `MessageSent()`,
was already implemented, however it was not called when the peer was sent data.
To fix this, a call to `MessageSent()` was made in the `taskWorker()` function,
which is where both the message in question and the Bitswap engine were
available to make the call. `MessageSent()` requires the peer's ID and
`BitSwapMessage` as its arguments, the latter of which had to be created by
making a new `BitSwapMessage`, then the block being sent was added to the new
message.

Note that, similar to the analagous call to `MessageReceived()`, records *all*
of the bytes sent to a particular user. At some point, both of these should be
updated to only record the numbers of *useful* bytes sent and received between
peers.
