[PATCH 0/4] monitor/hmp: cleanup monitor_event() and suspend_cnt

[Paolo Bonzini]

monitor_event() is not using monitor_suspend() and monitor_resume()
even though that is the desired outcome of moving out of and back into
the monitor with Ctrl-a c.

While cleaning this up, make the locking of several fields in struct
Monitor less esoteric, i.e. protect them just with mon_lock.  This gets
rid of one of the last two cases where qatomic_mb_read()/qatomic_mb_set()
pair is used to achieve a semblance of sequential consistency.

Paolo Bonzini (4):
  monitor: use QEMU_LOCK_GUARD a bit more
  monitor: allow calling monitor_resume under mon_lock
  monitor: add more *_locked() functions
  monitor: do not use mb_read/mb_set for suspend_cnt
