* Fixed tests

* fixed rpc helper tests

* fixed rpc_tests

* fixed mock/status_test

* fixed typo

* fix dot imports.

Reasons:
1) all deps we're using should be passing tests (including external)
2) deps can require complicated setup for testing
3) the person responsible for releasing Tendermint should be cautious
when updating a dep

* de-mystify tests & run them in parallel (#1031)

* test optimization for jenkins (#1093)

* makefile cleanup

* tests: split fast and slow go tests, closes #1055

* pr comments

* restore circle conditions

* fix need_abci

* ...

* docker run: no :Z for circle?

* Remove cmd breaking comment

To achieve faster feedback cycles for our feature PRs this change
reduces the average buildtime from 35 to ~6min by utilising their new
2.0 offering based on docker and nomad. We make use of parallel build
steps wherever possible so that the duration is determined by the
slowest test suite (p2p).

This is an intermediate step until we move our CI/CD completely
on-premise for more control and added security.

Refs #1249

* remove accidental binary

* docs: s/Dummy&dummy/KVStore&kvstore/g

* glide update to abci

* update abci import paths

* dummy begone, hello kvstore

* RequestInitChain needs genesisBytes

* glide update

* Switch to dep from glide for dependency management

* Update CI dockerfile to use dep instead of glide

* Wrong file extension

* Run 'dep ensure' after copying code

* Install glide to handle abci dependencies in testing

* Use `dep ensure -vendor-only` to setup vendor directory before installing source code on ci

* 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
