Dropping monitor.h breaks the build with the following error:

"""
/home/lcapitulino/work/src/upstream/qmp-unstable/cpus.c: In function 
‘qmp_inject_nmi’:
/home/lcapitulino/work/src/upstream/qmp-unstable/cpus.c:1490:9: error: implicit 
declaration of function ‘monitor_get_cpu_index’

         if (cpu->env.cpu_num == monitor_get_cpu_index()) {

"""

I've added it back then.
