Jan Dittberner 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.

Jan Dittberner 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.

Jan Dittberner 47d5b2afff Improve configuration, implement setup mode
- implement a dedicated setup mode for creating CA certificates that is
  triggered by the '-setup' command line flag
- switch to YAML configuration for comment support and more human
  readable syntax. Format documentation is in docs/config.sample.yaml
- move HSM related code to pkg/hsm
- improve consistency checks in pkg/config

Jan Dittberner de997913cf Implement configuration and CA hierarchy setup
This commit implements a mechanism to load CA configuration dynamically from
JSON files. Missing keys and certificates can be generated in a PKCS#11 HSM
or Smartcard. Certificates are stored as PEM encoded .crt files in the
filesystem.

The default PKCS#11 module (softhsm2) is now loaded from a platform specific
path using go:build comments.

- add test to use a private key from softhsm to create a root
  certificate
