[PATCH v5 19/36] qemu_monitor: Make monitor callbacks optional

[Chris Venteicher <cventeic@xxxxxxxxxx>]

Qemu process code for capababilities doesn't use monitor callbacks and
defines empty callback functions.

Allow NULL to be passed to qemuMonitorOpen for callbacks and remove the
empty functions from the QMP process code.
