f0d456dd13 Protocol improvements
- add a client generated command ID for tracing commands and responses
- define protocol delimiter in protocol.CobsDelimiter
- apply code simplifications suggested by golangci-lint
- add Makefile
- add compile time build information for signer binary
- make sure that dependencies for msgpackgen survive go mod tidy
- extract MsgPackHandler into its own file
- add CRL number to fetch CRL response
- remove port.Flush() to avoid removing written data before it reaches the
  client

8e443bd8b4 Implement protocol improvements
This commit implements a client and server side state machine
for the serial protocol.

2de592d30c Implement command type handling
This commit changes the wire protocol to split between command
announcement and command payload to allow proper typing of sent and
received msgpack messages.

CRL fetching has been implemented as second command after the existing
health check command.

response data to the messages returned by the health command.

3107ad8abb Implement serial link and protocol handling infrastructure
This commit adds basic serial link and protocol support. None of the commands
from the docs/design.md document is implemented yet.

The following new packages have been added:

- seriallink containing the serial link handler including COBS decoding and
  encoding
- protocol containing the protocol handler including msgpack unmarshalling
  and marshaling
- health containing a rudimentary health check implementation
- messages containing command and response types and generated msgpack
  marshaling code

A client simulation command has been added in cmd/clientsim.

README.md got instructions how to run the client simulator. The
docs/config.sample.yaml contains a new section for the serial connection
parameters.
