qemu-char: rename qemu_chr_event to qemu_chr_be_event and make it public
Rename qemu_chr_event to qemu_chr_be_event, since it is only to be called by backends and make it public so that it can be used by chardev code which lives outside of qemu-char.c Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
