From: Li Liu <john.li...@huawei.com> qtest_log_fp should be inited before qemu_chr_add_handlers. If not the log dumped from callback functions may be lost.
easy to reproduce it by command: "QTEST_LOG=1 QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 gtester -k --verbose -m=quick tests/qdev-monitor-test" The log "[I xxxxxx] OPENED" should be printed out by qtest_event, but does not.
