Kevin Wolf 8e9119a807 hmp: Fail gracefully if chardev is already in use ... Trying to attach a HMP monitor to a chardev that is already in use results in a crash because monitor_init_hmp() passes &error_abort to qemu_chr_fe_init(): $ ./x86_64-softmmu/qemu-system-x86_64 --chardev stdio,id=foo --mon foo --mon foo QEMU 4.2.50 monitor - type 'help' for more information (qemu) Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:220: qemu-system-x86_64: --mon foo: Device 'foo' is in use Abgebrochen (Speicherabzug geschrieben) Fix this by allowing monitor_init_hmp() to return an error and passing any error in qemu_chr_fe_init() to its caller instead of aborting.
