[Qemu-devel] [PATCH] qemu-error: remove dependency of stubs on monitor

[Paolo Bonzini <pbonzini@redhat.com>]

Leave the implementation of error_printf, error_printf_unless_qmp
and error_vprintf to libqemustub.a and monitor.c, so that we can
remove the monitor_printf and monitor_vprintf stubs.

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

        This should help shutting up the vmstate unit tests.
