[PATCH v1 01/10] monitor: expose monitor_puts to rest of code

[Alex Bennée]

This helps us construct strings elsewhere before echoing to the
monitor. It avoids having to jump through hoops like:

  monitor_printf(mon, "%s", s->str);

It will be useful in following patches but for now convert all
existing plain "%s" printfs to use the _puts api.

 Also, you have to add the function's prototype to the hmp.h file.
