## Description
This PR removes simple prefix from all types in the crypto/merkle directory.
The two proto types `Proof` & `ProofOp` have been moved to the `proto/crypto/merkle` directory.
proto messge `Proof` was renamed to `ProofOps` and `SimpleProof` message to `Proof`.
Closes: #2755
Creates Amnesia Evidence which is formed from Potential Amnesia Evidence with either a matching proof or after a period of time denoted as the Amnesia Trial Period. This also adds the code necessary so that Amnesia Evidence can be validated and committed on a block
Migrates the p2p connections to Protobuf. Supersedes #4800.
gogoproto's `NewDelimitedReader()` uses an internal buffer, which makes it unsuitable for reading individual messages from a shared reader (since any remaining data in the buffer will be discarded). We therefore add a new `protoio` package with an unbuffered `NewDelimitedReader()`. Additionally, the `NewDelimitedWriter()` returns the number of bytes written, and we've added `MarshalDelimited()` and `UnmarshalDelimited()`, to ease migration of existing code.
## Description
regenerate proto stubs
I do find max_num to be vague. possibly renaming to max_entries or max_evidence_entries may be more descriptive?
Closes: #XXX
- regenerate proto using docker image
- on proto breakage a different compiler is used to generate some more helper functions, on master the same one os not used, reverting back to the one used on master to undo further confusion till proto-breakage is merged

Fixes https://github.com/tendermint/tendermint/issues/1162
Databases as a service!
Can now access Databases as a remote service
via gRPC for performance and easy deployment.
The caveat is that each service is stateful in regards to
the DB i.e. each unique service uses only one unique DB
but nonetheless multiple clients can access it.
A full standalone example
```go
package main
import (
"bytes"
"context"
"log"
grpcdb "github.com/tendermint/tmlibs/grpcdb"
protodb "github.com/tendermint/tmlibs/proto"
)
func main() {
addr := ":8998"
go func() {
if err := grpcdb.BindRemoteDBServer(addr); err != nil {
log.Fatalf("BindRemoteDBServer: %v", err)
}
}()
client, err := grpcdb.NewClient(addr, false)
if err != nil {
log.Fatalf("Failed to create grpcDB client: %v", err)
}
ctx := context.Background()
// 1. Initialize the DB
in := &protodb.Init{
Type: "leveldb",
Name: "grpc-uno-test",
Dir: ".",
}
if _, err := client.Init(ctx, in); err != nil {
log.Fatalf("Init error: %v", err)
}
// 2. Now it can be used!
query1 := &protodb.Entity{Key: []byte("Project"), Value:
[]byte("Tmlibs-on-gRPC")}
if _, err := client.SetSync(ctx, query1); err != nil {
log.Fatalf("SetSync err: %v", err)
}
query2 := &protodb.Entity{Key: []byte("Project")}
read, err := client.Get(ctx, query2)
if err != nil {
log.Fatalf("Get err: %v", err)
}
if g, w := read.Value, []byte("Tmlibs-on-gRPC"); !bytes.Equal(g, w) {
log.Fatalf("got= (%q ==> % X)\nwant=(%q ==> % X)", g, g, w, w)
}
}
