qemu-char: using qemu_set_nonblock() instead of fcntl(O_NONBLOCK)
Technically, fcntl(soc, F_SETFL, O_NONBLOCK) is incorrect since it clobbers all other file flags. We can use F_GETFL to get the current flags, set or clear the O_NONBLOCK flag, then use F_SETFL to set the flags. Using the qemu_set_nonblock() wrapper.
