065bd3f0be *: introduce Genesis protocol configuration
This section contains genesis-related settings including genesis-related or natives-related
extensions. Currently it includes the set of node roles that may be designated
duing the native Designation contract initialisation.

Close #3156.

6b21ad9922 *: replace interface{} with any keyword
Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.

8746d9877e keys: move from btcd/btcec to decred/secp256k1 package
There is a security issue found in github.com/btcsuite/btcd that we don't care
about (we're only using 256k1 implementation), but GitHub complains about
it. We could update to github.com/btcsuite/btcd/btcec/v2, but it's now just a
thin wrapper over github.com/decred/dcrd/dcrec/secp256k1/v4, so we better use
it directly.

bf3415e2bc emit: introduce CheckSig function
Which allows to create verification scripts without keys.PublicKey which is
convenient in some cases where we already have serialized key and don't want
to waste time decompressing it.

cda1c75db3 core: drop GetStandBy* methods
They're misleading now that we have variable number of committee

4803cc15c7 keys: add (*PublicKey).DecodeBytes benchmark
Attempts to reuse elliptic.Unmarshal() and elliptic.UnmarshalCompressed() lead
to this:
name                 old time/op    new time/op    delta
PublicDecodeBytes-8    59.5µs ± 2%    61.8µs ± 1%  +3.78%  (p=0.000 n=10+9)

name                 old alloc/op   new alloc/op   delta
PublicDecodeBytes-8    3.99kB ± 0%    4.27kB ± 0%  +6.81%  (p=0.000 n=9+10)

name                 old allocs/op  new allocs/op  delta
PublicDecodeBytes-8       136 ± 0%       135 ± 0%  -0.74%  (p=0.000 n=10+10)

So it makes no sense. Refs. #1319.

217d7bdf44 keys: add equality benchmark
Go 1.15 provides native (*ecdsa.PublicKey).Equal method, but we can't drop our
own Equal because the types are different and there is still code using our
Equal (forcing it to convert types is counterproductive), while changing
(*PublicKey).Equal to use (*ecdsa.PublicKey).Equal internally with some kind of

  (*ecdsa.PublicKey)(p).Equal((*ecdsa.PublicKey)(key))

slows it down:

name           old time/op    new time/op    delta
PublicEqual-8    14.9ns ± 1%    18.4ns ± 2%  +23.55%  (p=0.000 n=9+10)

name           old alloc/op   new alloc/op   delta
PublicEqual-8     0.00B          0.00B          ~     (all equal)

name           old allocs/op  new allocs/op  delta
PublicEqual-8      0.00           0.00          ~     (all equal)

So leave it as is, but add this micro-bench. Refs. #1319.

f5f58a7e91 keys: add simple LRU key cache for 1024 elements
The cost of Y calculation from X is comparable with signature check, so it
reduces witness check overhead by ~30% for cached keys and gives ~5% overall
boost in TPS.
