## Issue

Implement a new subcommand: tendermint debug. This subcommand itself has two subcommands:

    $ tendermint debug kill <pid> </path/to/out.zip> --home=</path/to/app.d>

Writes debug info into a compressed archive. The archive will contain the following:

├── config.toml
├── consensus_state.json
├── net_info.json
├── stacktrace.out
├── status.json
└── wal

The Tendermint process will be killed.

    $ tendermint debug dump </path/to/out> --home=</path/to/app.d>

This command will perform similar to kill except it only polls the node and dumps debugging data every frequency seconds to a compressed archive under a given destination directory. Each archive will contain:

├── consensus_state.json
├── goroutine.out
├── heap.out
├── net_info.json
├── status.json
└── wal

Note:

    goroutine.out and heap.out will only be written if a profile address is provided and is operational.
    This command is blocking and will log any error.

closes: #3249

Commits:

in general moved everything required for making block requests smarter in the poolRoutine

added a simple map of heights to keep track of what will need to be requested next

added a few more tests

send errors (RemovePeer) from switch on a different channel than the
one receiving blocks
renamed channels

* Added timeout on next block needed to advance

* updating docs and cleanup

* fix issue in test from previous cleanup

* cleanup

* Added termination scenarios, tests and more cleanup

* small fixes to adr, comments and cleanup

* Fix bug in sendRequest()

If we tried to send a request to a peer not present in the switch, a
missing continue statement caused the request to be blackholed in a peer
that was removed and never retried.

While this bug was manifesting, the reactor kept asking for other
blocks that would be stored and never consumed. Added the number of
unconsumed blocks in the math for requesting blocks ahead of current
processing height so eventually there will be no more blocks requested
until the already received ones are consumed.

* remove bpPeer's didTimeout field

* Use distinct err codes for peer timeout and FSM timeouts

lite client works (tested manually)

godoc comments

httpclient: do not close the out channel

use TimeoutBroadcastTxCommit

no timeout for unsubscribe

but 1s Local (5s HTTP) timeout for resubscribe

format code

change Subscribe#out cap to 1

and replace config vars with RPCConfig

TimeoutBroadcastTxCommit can't be greater than rpcserver.WriteTimeout

rpc: Context as first parameter to all functions

reformat code

fixes after my own review
