[PATCH v4 1/4] target/arm: Restrict 'qapi-commands-machine.h' to system emulation

[Philippe Mathieu-Daudé]

Since commit a0e61807a3 ("qapi: Remove QMP events and commands from
user-mode builds") we don't generate the "qapi-commands-machine.h"
header in a user-emulation-only build.

Move the QMP functions from helper.c (which is always compiled)
to monitor.c (which is only compiled when system-emulation
is selected).  Rename monitor.c to arm-qmp-cmds.c.
