From 920824165c49bfbd1e0e9e07fd92e0bbbf32aea3 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 13 Jun 2019 17:34:03 +0200 Subject: monitor: Split Monitor.flags into separate bools Monitor.flags contains three different flags: One to distinguish HMP from QMP; one specific to HMP (MONITOR_USE_READLINE) that is ignored with QMP; and another one specific to QMP (MONITOR_USE_PRETTY) that is ignored with HMP. Split the flags field into three bools and move them to the right subclass. Flags are still in use for the monitor_init() interface.
