Call qemu_notify_event() after updating events. Otherwise, If we add an event for -is-writeable but the socket is already writeable there may be a delay before the event callback is actually triggered. Those delays would in particular hurt performance during BIOS boot and when the GRUB bootloader reads the kernel and initrd. But first call out to the socket write functions directly, and only set up the write event if the socket is full. This will happen very rarely and this improves performance.
