      introduce adaptive queue for DHT dials. · 5e74c4a6
      Raúl Kripalani authored 
      This patch introduces an adaptive dial queue that spawns a dynamically sized
set of goroutines to preemptively stage dials for later handoff to the DHT
protocol for RPC. It identifies backpressure on both ends (dial consumers and
dial producers), and takes compensating action by adjusting the worker pool.

We start with `DialQueueMinParallelism` number of workers (6), and scale up
and down based on demand and supply of dialled peers.

The following events trigger scaling:
- we scale up when we can't immediately return a successful dial to a new
  consumer.
- we scale down when we've been idle for a while waiting for new dial
  attempts.
- we scale down when we complete a dial and realise nobody was waiting for it.

Dialler throttling (e.g. FD limit exceeded) is a concern, as we can easily
spin up more workers to compensate, and end up adding fuel to the fire. Since
we have no deterministic way to detect this for now, we hard-limit concurrency
to `DialQueueMaxParallelism` (20).

      Remove outdated package documentation · 70d5802f
      Gustvo Chain authored 
      Both, dht.go and dht_bootstrap.go duplicate the package documentation.
The whole block had been moved to doc.go

Also query.go provides documentation for query package but now it
belongs to dht package, so it's been removed.

      fix a potential DHT query hang · eb3e7fe9
      Steven Allen authored 
      Without this, one of the workers may hang when trying to re-grab the rate-limit
after dialing. I believe this may be what's causing some of our DHT requests to
stall (evidence: massive goroutine buildup on the gateways).

      Fixes for dht findpeer queries · 00b46e0c
      Jeromy authored 
      First, we use Alpha instead of K as the number of peers we grab from the
routing table (as per the kademlia paper).

Second, we don't use a size limited set for the 'GetClosestPeers' query.
We're going to process more than K peers before we find the K closest
peers.

Third, Change GetClosestPeers to actually return the K Closest peers,
not a hodge podge of peers that it found on the way to finding the
closest peers.
