* update btcd fork for v0.1.1

* changelog

* crypto: revert to mainline Go crypto lib

We used to use a fork for a modified bcrypt so we could pass our own
randomness but this was largely unecessary, unused, and a burden.
So now we just use the mainline Go crypto lib.

* changelog

* fix tests

* version and changelog

* 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

because
- they are locked in .lock file already
- individual dependencies can be updated with `dep ensure -update XXX`
- review process (and ^^^) should help us prevent accidental updates

Closes #2798

* WIP: update to amino 0.14.0

* update Changelog

* Update to latest amino version (v0.14.0)

* catch up with amino changes in
https://github.com/tendermint/go-amino/pull/222

* WIP: update to amino v0.13.0

* update to fixed amino release

* types: test tm2pm on fully populated header

* upgrade for amino v0.13.0-rc0

* fix lint

* comment out final test

* ed25519: use golang/x/crypto fork

* changelog

* gix GenerateFromPassword

* fixes from review

Why:
original fork is abandoned and not supported anymore.

Changes:
- LevelDB 1.19 (LevelDB and Snappy are both compiled and linked statically, so while you will not need them installed on your target machine, you should have a roughly compatible version of libstdc++.)
- snappy and lz4 libs included by default

* crypto/secp256k1: Fix signature malleability, adopt more efficient encoding

This removes signature malleability per ADR 14, and makes secp match
the encoding in ADR 15.

* (squash this) add lock

Closes #1944

This adds a new makefile command, which is used in CI linting, `make check_dep`.
This ensures the toml is in sync with the lock, and that were not pinning to a
branch in any repository.

This also adapts `make get_vendor_deps` to check the lock, in addition to
populating the vendor directory. This removes the need for `make ensure_deps`.

This makes `make get_vendor_deps` consistent between tendermint and the sdk.

- leave protobuf on 1.1.1 for grpc import fixes
- amino v0.11 breaks tendermint - revert to v0.10.1

Refs #1883

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

- also reformat code and order imports

gogoproto.nullable compatible with GRPC downstream of ABCI and libs
protbuf types

This reverts commit d02c5d1e30.

* limit the number of requests in flights for Prometheus server

Closes #1804

Default to 1 because usually there's just one collector.

* config: Up default for prom connections

This reverts commit 2902ab1a14.

Also, fix consensus liveness issue.

Should be paired with https://github.com/tendermint/iavl/pull/65.

Refs #1740

also, expose limit option for number concurrent streams for gRPC
(unlimited by default)

This reverts commit 96a3502

- also delete ledger code and deps (thx cwgoes)

Signed-off-by: Liamsi <Liamsi@users.noreply.github.com>

- fundraiser compatibility for HD keys (BIP 39 & BIP 32 / BIP 44)

* Switch ports 466xx to be 266xx
This is done so the default ports aren't in the linux kernel's default ephemeral port range.

* Update ABCI import

* Bump cache on circleci

* Get more verbose output for debugging

* Bump abci dependency

* Fix accidental change of a block header's hash

* pin abci release

* Return errors on priv.Sign(), priv.PubKey()

* Add CreateLedger, CreateOffline

* Add switch on .Sign() for Ledger wallets

* Add offline signing switch on .Sign()

* Use MustUnmarshalBinaryBare()

* Add confirmation to delete offline/Ledger keys

* Lowercase error message

* Add human-readable .GetType() function to Info interface

* Rename CryptoAlgo => SignAlgo

* assert.Nil(t, err) => assert.NoError(t, err)
