* OriginalAddr -> SocketAddr
OriginalAddr records the originally dialed address for outbound peers,
rather than the peer's self reported address. For inbound peers, it was
nil. Here, we rename it to SocketAddr and for inbound peers, set it to
the RemoteAddr of the connection.
* use SocketAddr
Numerous places in the code call peer.NodeInfo().NetAddress().
However, this call to NetAddress() may perform a DNS lookup if the
reported NodeInfo.ListenAddr includes a name. Failure of this lookup
returns a nil address, which can lead to panics in the code.
Instead, call peer.SocketAddr() to return the static address of the
connection.
* remove nodeInfo.NetAddress()
Expose `transport.NetAddress()`, a static result determined
when the transport is created. Removing NetAddress() from the nodeInfo
prevents accidental DNS lookups.

* p2p/conn: FlushStop. Use in pex. Closes#2092
In seed mode, we call StopPeer immediately after Send.
Since flushing msgs to the peer happens in the background,
the peer connection is often closed before the messages are
actually sent out. The new FlushStop method allows all msgs
to first be written and flushed out on the conn before it is closed.
* fix dummy peer
* typo
* fixes from review
* more comments
* ensure pex doesn't call FlushStop more than once
FlushStop is not safe to call more than once,
but we call it from Receive in a go-routine so Receive
doesn't block.
To ensure we only call it once, we use the lastReceivedRequests
map - if an entry already exists, then FlushStop should already have
been called and we can return.

Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.
Ref discussion: https://github.com/tendermint/tendermint/pull/1966Closes#1956
This commit switches all usage of math/rand to cmn's rand. The only
exceptions are within the random file itself, the tools package, and the
crypto package. In tools you don't want it to lock between the go-routines.
The crypto package doesn't use it so the crypto package have no other
dependencies within tendermint/tendermint for easier portability.
Crypto/rand usage is unadjusted.
Closes#1343
* Switch ports 466xx to be 266xx
This is done so the default ports aren't in the linux kernel's default ephemeral port range.
* Update ABCI import
* Bump cache on circleci
* Get more verbose output for debugging
* Bump abci dependency
* Fix accidental change of a block header's hash
* pin abci release
* use increment and decrement operators.
* remove unnecessary else branches.
* fix package comment with leading space.
* fix receiver names.
* fix error strings.
* remove omittable code.
* remove redundant return statement.
* Revert changes (code is generated.)
* use cfg as receiver name for all config-related types.
* use lsi as the receiver name for the LastSignedInfo type.
* expose AuthEnc in the P2P config
if AuthEnc is true, dialed peers must have a node ID in the address and
it must match the persistent pubkey from the secret handshake.
Refs #1157
* fixes after my own review
* fix docs
* fix build failure

```
* p2p: introduce peerConn to simplify peer creation
* Introduce `peerConn` containing the known fields of `peer`
* `peer` only created in `sw.addPeer` once handshake is complete and NodeInfo is checked
* Eliminates some mutable variables and makes the code flow better
* Simplifies the `newXxxPeer` funcs
* Use ID instead of PubKey where possible.
* SetPubKeyFilter -> SetIDFilter
* nodeInfo.Validate takes ID
* remove peer.PubKey()
* persistent node ids
* fixes from review
* test: use ip_plus_id.sh more
* fix invalid memory panic during fast_sync test
