![Ethan Buchman](/avatar/91dd51f38be716f8c29da7f4f656bc16) p2p: introduce peerConn to simplify peer creation (#1226)
* 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/pex/pex_reactor_test.go:288:88: cannot use seed.NodeInfo().NetAddress() (type *p2p.NetAddress) as type string in array or slice literal
```
* 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
```

- Configuration
- =============
-
- Tendermint Core can be configured via a TOML file in
- ``$TMHOME/config/config.toml``. Some of these parameters can be overridden by
- command-line flags. For most users, the options in the ``##### main
- base configuration options #####`` are intended to be modified while
- config options further below are intended for advance power users.
-
- Config options
- ~~~~~~~~~~~~~~
-
- The default configuration file create by ``tendermint init`` has all
- the parameters set with their default values. It will look something
- like the file below, however, double check by inspecting the
- ``config.toml`` created with your version of ``tendermint`` installed:
-
- ::
-
- # This is a TOML config file.
- # For more information, see https://github.com/toml-lang/toml
-
