qemuboot.bbclass: add it for runqemu
It saves vars in ${DEPLOY_DIR_IMAGE}/<image>.qemuboot.conf, and runqemu will read it. The bsp which can be boot by runqemu will inherit it.

1# Help runqemu boot target board, "QB" means Qemu Boot, the following
2# vars can be set in conf files, such as <bsp.conf> to make it can be
3# boot by runqemu:
4#
5# QB_SYSTEM_NAME: qemu name, e.g., "qemu-system-i386"
6# QB_OPT_APPEND: options to append to qemu, e.g., "-show-cursor"
7# QB_DEFAULT_KERNEL: default kernel to boot, e.g., "bzImage"
8# QB_DEFAULT_FSTYPE: default FSTYPE to boot, e.g., "ext4"
9# QB_MEM: memory, e.g., "-m 512"
10# QB_MACHINE: qemu machine, e.g., "-machine virt"
11# QB_CPU: qemu cpu, e.g., "-cpu qemu32"
12# QB_CPU_KVM: the similar to QB_CPU, but used when kvm, e.g., '-cpu kvm64',
13# set it when support kvm.
14# QB_KERNEL_CMDLINE_APPEND: options to append to kernel's -append
15# option, e.g., "console=ttyS0 console=tty"
16# QB_DTB: qemu dtb name
17# QB_AUDIO_DRV: qemu audio driver, e.g., "alsa", set it when support audio
18# QB_AUDIO_OPT: qemu audio option, e.g., "-soundhw ac97,es1370", used
19# when QB_AUDIO_DRV is set.
20# QB_KERNEL_ROOT: kernel's root, e.g., /dev/vda
21# QB_TAP_OPT: netowrk option for 'tap' mode, e.g.,
22# "-netdev tap,id=net0,ifname=@TAP@,script=no,downscript=no -device virtio-net-device,netdev=net0"
23# Note, runqemu will replace "@TAP@" with the one which is used, such as tap0, tap1 ...
24# QB_SLIRP_OPT: network option for SLIRP mode, e.g.,
25# "-netdev user,id=net0 -device virtio-net-device,netdev=net0"
26# QB_ROOTFS_OPT: used as rootfs, e.g.,
27# "-drive id=disk0,file=@ROOTFS@,if=none,format=raw -device virtio-blk-device,drive=disk0"
28# Note, runqemu will replace "@ROOTFS@" with the one which is used, such as core-image-minimal-qemuarm64.ext4.
29# QB_SERIAL_OPT: serial port, e.g., "-serial mon:stdio"
30# QB_TCPSERIAL_OPT: tcp serial port option, e.g.,
31# " -device virtio-serial-device -chardev socket,id=virtcon,port=@PORT@,host=127.0.0.1 -device virtconsole,chardev=virtcon"
32# Note, runqemu will replace "@PORT@" with the port number which is used.

35# IMAGE_CLASSES += "qemuboot"
