go-peerstream transports: muxado

[jbenet]

This PR updates go-peerstream to the new abstracted
transport version. It also changes the default transport
to http://github.com/inconshreveable/muxado

@whyrusleeping: try out this branch with provider fixes
and see if it gets rid of the hang you were experiencing.
If not, the problem's on our side.

@whyrusleeping you might also want to try 6ad158d directly, as a change to peerstream may have fixed things too, but it's a very low probability. (too bad i cant repro the problem or i'd try :( )

Hm. this may not actually work. i rebased provides-rewrite on this (locally) and running dhtHell to get things like this:

07:28:58.221 ERROR    bitswap: Bitswap ReceiveError: unexpected EOF bitswap.go:331
07:28:58.233 ERROR        dht: closestPeers query run error: routing: not found routing.go:199
07:28:58.244 ERROR    bitswap: Bitswap ReceiveError: proto: can't skip unknown wire type 6 for bitswap_message_pb.Message bitswap.go:331

Seems like the streams are getting a bit mixed up or something... the protobufs aren't decoding properly.

Though... it still manages to succeed:

Read File Succeeded: 932193.312047 bytes per second

[whyrusleeping]

If you see it succeed then the file definitely somehow managed to make it over correctly... Thats strange.

[whyrusleeping]

I almost suspect that the unexpected EOF could be the result of a context cancelling and closing a connection mid-write.

this was reverted, in favor of #484
