monitor: separate QMP parser and dispatcher
Originally QMP goes through these steps:
JSON Parser --> QMP Dispatcher --> Respond
/|\ (2) (3) |
(1) | \|/ (4)
+--------- main thread --------+
This patch does this:
JSON Parser QMP Dispatcher --> Respond
/|\ | /|\ (4) |
| | (2) | (3) | (5)
(1) | +-----> | \|/
+--------- main thread <-------+
So the parsing job and the dispatching job is isolated now. It gives us
a chance in follow up patches to totally move the parser outside.
The isolation is done using one QEMUBH. Only one dispatcher QEMUBH is
used for all the monitors.
