6485e68beb Use ethereum's secp256k1 lib (#3234)
* switch from fork (tendermint/btcd) to orig package (btcsuite/btcd); also

 - remove obsolete check in test `size != -1` is always true
 - WIP as the serialization still needs to be wrapped

* WIP: wrap signature & privkey, pubkey needs to be wrapped as well

* wrap pubkey too

* use "github.com/ethereum/go-ethereum/crypto/secp256k1" if cgo is
available, else use "github.com/btcsuite/btcd/btcec" and take care of
lower-S when verifying

Annoyingly, had to disable pruning when importing
github.com/ethereum/go-ethereum/ :-/

* update comment

* update comment

* emulate signature_nocgo.go for additional benchmarks:
592bf6a59c/crypto/signature_nocgo.go (L60-L76)

* use our format (r || s) in lower-s form when in the non-cgo case

* remove comment about using the C library directly

* vendor github.com/btcsuite/btcd too

* Add test for the !cgo case

* update changelog pending

124d0db1e0 Make txs and evidencelist use merkle.SimpleHashFromBytes to create hash (#2635)
This is a performance regression, but will also spare the types directory
from knowing about RFC 6962, which is a more correct abstraction. For txs
this performance hit will be fixed soon with #2603. For evidence, the
performance impact is negligible due to it being capped at a small number.

cases we have. (Symmetrically encrypting the keys in the sdk keys package)

0bd4fb96f0 crypto: Add benchmarking code for signature schemes (#2061)
* crypto: Add benchmarking code for signature schemes

This does a slight refactor for the key generation code. It now calls a
seperate unexported method to allow generation from a reader. I think this
will actually reduce time in generation, due to no longer initializing an
extra slice. This was needed in order to enable benchmarking.

This uses an internal package for the benchmarking code, so that this can
be standardized without being exported in the public API. The benchmarking
code is derived from agl/ed25519's benchmarking code, and has copied the
license over.
