Summary

Add three simple hooks to the debugger allowing for a loaded MAC policy
to intervene if desired:

  1. Before invoking the kdb backend
  2. Before ddb command registration
  3. Before ddb command execution

We extend struct db_command with a private pointer and two flag bits
reserved for policy use.

mac_kdb.c might be a better name for this file. "debugger" sounds too generic to me.
