machine: query mem-merge machine property
Running
qemu-bin ... -machine pc,mem-merge=on
leads to crash:
x86_64-softmmu/qemu-system-x86_64 -machine pc,dump-guest-core=on
qemu-system-x86_64: qemu/util/qemu-option.c:387: qemu_opt_get_bool_helper:
Assertion `opt->desc && opt->desc->type == QEMU_OPT_BOOL' failed. Aborted
(core dumped)
This happens because the commit e79d5a6 ("machine: remove qemu_machine_opts
global list") removed the global option descriptions and moved them to
MachineState's QOM properties.
Fix this by querying machine properties through designated wrappers.
