Closes: #2460

* Pass http.ServeTLS() errors back to the caller
* Update CHANGELOG
* Amend StartHTTPServer() too for consistency's sake
* Revert "Amend StartHTTPServer() too for consistency's sake"
This reverts commit 23bfb4c2e9.

* Add /consensus_params endpoint
* Incorporated change https://github.com/tendermint/tendermint/pull/2415#discussion_r219078049
* Fixed an error in pervious commit

We are swapping the exisiting listener implementation with the newly
introduced Transport and its default implementation MultiplexTransport,
removing a large chunk of old connection setup and handling scattered
over the Peer and Switch code. The Switch requires a Transport now and
handles externally passed Peer filters.

* [rpc] transform /status result.node_info.other into map
* amino does not support maps, duh

Reasons:
- this was a bad patch for something not well understood

Lessons learned:
- nobody should be modifying code without understanding the problem
first. it will only result in more technical debt and code rot.
- we never hide information when we suspect a bug or we'not sure what's
going on.

This PR changes ABCI time format from int64 (Unix seconds) to WKT (WellKnownType) google.protobuf.Timestamp.

Refs #1857

Reasons:

better precision
standard DT for proto

* update Gopkg.lock
* [makefile] remove extra grep
    - go list excludes vendor by default now
* proto3 timestamp
* [docs/abci-spec] note about serialisation format
* make time non-nullable

also, make running Prometheus server optional.

Closes #2019

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.

Closes #1932 (#1986)

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.

fixes for tools repo merge (#1943)

This reverts commit d02c5d1e30.

except now we calculate the max size using the maxPacketMsgSize()
function, which frees developers from having to know amino encoding
details.

plus, 10 additional bytes are added to leave the room for amino upgrades
(both making it more efficient / less efficient)
