* chore: skeleton files for any renderer
* feat: first cut at Any renderer and tests
* test: Any fields, more tests, rename lookup by field
* docs: make Any example match the stated spec, and the implementation.
* refactor: use protojson for better test case legibility
* test: use protocmp for proto equality
See https://developers.google.com/protocol-buffers/docs/reference/go/faq#deepequal
* refactor: use json.RawMessage instead of remarshalling
* refactor: consistent pointer receiver for Textual
## Description
TLDR; check for `s.IsOverHalfOrder()` with less steps
Before this PR:
```go
// parse the signature:
signature := signatureFromBytes(sigStr)
// Reject malleable signatures. libsecp256k1 does this check but btcec doesn't.
// see: https://github.com/ethereum/go-ethereum/blob/f9401ae011ddf7f8d2d95020b7446c17f8d98dc1/crypto/signature_nocgo.go#L90-L93
// Serialize() would negate S value if it is over half order.
// Hence, if the signature is different after Serialize() if should be rejected.
modifiedSignature, parseErr := ecdsa.ParseDERSignature(signature.Serialize())
if parseErr != nil {
return false
}
if !signature.IsEqual(modifiedSignature) {
return false
}
```
It's serializing the signature into a new variable and then comparing if both are equal. Inside `Serialize()` we have:
https://github.com/decred/dcrd/blob/5d537320a0fe2357daf444cc12c62680579689da/dcrec/secp256k1/ecdsa/signature.go#L88-L95
```go
// Ensure the S component of the signature is less than or equal to the half
// order of the group because both S and its negation are valid signatures
// modulo the order, so this forces a consistent choice to reduce signature
// malleability.
sigS := new(secp256k1.ModNScalar).Set(&sig.s)
if sigS.IsOverHalfOrder() {
sigS.Negate()
}
```
Before btcec update to v2:
Until btcec update this was simpler because S was exported in the signature: https://github.com/cosmos/cosmos-sdk/commit/ed9cd41396815bd236770f73bb30e083e63e8b64#diff-30a6b594e157a12a28bf8a26f65ab4de1dc3c65c8419e5756f0b9c25d9ce1a93L46
```go
if signature.S.Cmp(secp256k1halfN) > 0 {
return false
}
```
Closes: #XXXX

Simplifies and makes clearer the code in removeZeroCoins by
removing unnecessary checks that boiled down to still running
in the same final for loop.
Fixes#13958
## Description
Closes:
#13830#13827
- Rosetta `/network/status` response:
* populates `oldest_block_identifier` with `EarliestBlockHeight` from rpc syncInfo
* tries to populate `genesis_block_identifier` with block of height 1
* if block is not queryable, sets value of `InitialHeight` from genesis doc
* if not queryable sets same value as `oldest_block_identifier`
- Wrap `github.com/tendermint/tendermint/rpc/jsonrpc/types` errors to rosetta errors
- Split services into its own go files (account, block, mempool, network)
