* Fixed accepting integer IDs in requests for Tendermint RPC server (#2366)

* added a wrapper interface `jsonrpcid` that represents both string and int IDs in JSON-RPC requests/responses + custom JSON unmarshallers

* changed client-side code in RPC that uses it

* added extra tests for integer IDs

* updated CHANGELOG_PENDING, as suggested by PR instructions

* addressed PR comments

* added table driven tests for request type marshalling/unmarshalling
* expanded handler test to check IDs
* changed pending changelog note

* changed json rpc request/response unmarshalling to use empty interfaces and type switches on ID

* some cleanup

* Replaces our current http servers where connections stay open forever with ones with timeouts to prevent file descriptor exhaustion

* Use the correct handler

* Put in go routines

* fix err

* changelog

* rpc: export Read/WriteTimeout

The `broadcast_tx_commit` endpoint has it's own timeout.
If this is longer than the http server's WriteTimeout, the
user will receive an error. Here, we export the WriteTimeout
and set the broadcast_tx_commit timeout to be less than it.

In the future, we should use a config struct for the timeouts
to avoid the need to export. The broadcast_tx_commit timeout
may also become configurable, but we must check that it's less
than the server's WriteTimeout.

* Vagrantfile: install dev_tools

Follow-up on https://github.com/tendermint/tendermint/pull/2824

* update consensus params spec

* fix test name

* rpc_test: panic if failed to start listener

also
- remove http_server#MustListen
- align StartHTTPServer and StartHTTPAndTLSServer functions

* dep: allow minor releases for grpc

* Decouple StartHTTP{,AndTLS}Server from Listen()

This should help solve cosmos/cosmos-sdk#2715

* fix tm-monitor. more comments

* p2p: add protocol Version to NodeInfo

* update node pkg. remove extraneous version files

* update changelog and docs

* fix test

* p2p: Version -> ProtocolVersion; more ValidateBasic and tests

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.

also, return ErrNotStarted when trying to stop a not-running service

* libs: Remove usage of custom Fmt, in favor of fmt.Sprintf

Closes #2193

* Fix bug that was masked by custom Fmt!

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/1966

Closes #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

fixes for tools repo merge (#1943)

Jae: I don't know a good way to catch these errors in general, but
forcing pubsub's internal channel to have a capacity of 0 will reveal
bugs sooner, if the subscriber also has a 0 or small capacity ch to pull
from.
