      * fix: minimize time holding wantlist lock

Instead of holding the lock the entire time we prepare a message, hold the lock
while we retrieve the wantlist entries, process the entries without the lock,
retake the lock, then mark entries as sent.

This means:

1. We never sort entries while holding the lock.
2. We allocate exactly three times while holding the lock (once per entry list).

* fix: address code review

      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

      use CIDs directly as map keys · 77ea854e
      Steven Allen authored 
      1. Use a `taskEntryKey` *type* instead of a string (now that both peer IDs and
CIDs are hashable).
2. Get rid of all uses of `cid.KeyString` (mostly just for type safety). This
also means we don't need to parse the CID and allocate to convert it *back* from
a string.

      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.

      bitswap: protocol extension to handle cids · 591491b1
      Jeromy authored 
      This change adds the /ipfs/bitswap/1.1.0 protocol. The new protocol
adds a 'payload' field to the protobuf message and deprecates the
existing 'blocks' field. The 'payload' field is an array of pairs of cid
prefixes and block data. The cid prefixes are used to ensure the correct
codecs and hash functions are used to handle the block on the receiving
end.
