This means they will get a timestamp if timestamps are enabled, and they will go through the HMP monitor if one is configured. This commit also adds a call to error_init() to the binaries installed by QEMU. Since error_init() also calls error_set_progname(), this means that *-linux-user, *-bsd-user and qemu-pr-helper messages output with error_report, info_report, ... will slightly change: they will be prefixed by the binary name. glib debug messages are enabled through G_MESSAGES_DEBUG similarly to the glib default log handler. At the moment, this change will mostly impact SPICE logging if your spice version is >= 0.14.1. With older spice versions, this is not going to work as expected, but will not have any ill effect, so this call is not conditional on the SPICE version.
