Factor handle_bp_command into pieces:

Browse Source 
- Bug fix: return a syntax error if the wrong number of arguments are given.
- Add handle_bp_command_list() and handle_bp_command_set().
- Use temporary addr variable to eliminate redundant strtoul() calls.
- Place variable declarations at their point of first use.
