Log Message

monitor: Replace monitor_init() with monitor_init_{hmp, qmp}()

Most callers know which monitor type they want to have. Instead of
calling monitor_init() with flags that can describe both types of
monitors, make monitor_init_{hmp,qmp}() public interfaces that take
specific bools instead of flags and call these functions directly.
