runqemu: refactor it and remove machine knowledge
Previously, runqemu had hard coded machine knowledge, which limited its usage, for example, qemu can boot genericx86, but runqemu can't, we need edit runqemu/runqemu-internal a lot if we want to boot genericx86. Now bsp conf files can set vars to make it can be boot by runqemu, and qemuboot.bbclass will save these info to DEPLOY_DIR_IMAGE/qemuboot.conf. Please see qemuboot.bbclass' comments on how to set the vars. * Re-write it in python3, which can reduce lines from 1239 to about 750 lines * All the machine knowledges are gone * All of the TUN_ARCH knowledge are gone * All the previous options are preserved, and there is a new way to run runqemu: (it doesn't need run "bitake -e" in such a case) $ runqemu tmp/deploy/images/qemux86 or: $ runqemu tmp/deploy/images/qemuarm/<image>.ext4 or: $ runqemu tmp/deploy/images/qemuarm/qemuboot.conf * Fixed audio support, not limited on x86 or x86_64 * Fix SLIRP mode, add help message, avoid mixing with tap * Fix NFS boot, it will extract <image>.tar.bz2 or tar.gz to DEPLOY_DIR_IMAGE/<image>-nfsroot when no NFS_DIR, and remove it after stop. * More bsps can be boot, such as genericx86 and genericx86-64. * The patch for qemuzynq, qemuzynqmp, qemumicroblaze has been sent to meta-xilinx' mailing list. * I can't find any qemush4 bsp or how to build it, so it is not considered atm.

Usage: you can run this script with any valid combination
of the following environment variables (in any order):
KERNEL - the kernel image file to use
ROOTFS - the rootfs image file or nfsroot directory to use
MACHINE - the machine name (optional, autodetected from KERNEL filename if unspecified)
Simplified QEMU command-line options can be passed with:
- nographic - disables video console
- serial - enables a serial console on /dev/ttyS0
- kvm - enables KVM when running qemux86/qemux86-64 (VT-capable CPU required)
- kvm-vhost - enables KVM with vhost support when running qemux86/qemux86-64 (VT-capable CPU required)
+ nographic - disable video console
+ serial - enable a serial console on /dev/ttyS0
+ slirp - enable user networking, no root privileges is required
+ kvm - enable KVM when running x86/x86_64 (VT-capable CPU required)
+ kvm-vhost - enable KVM with vhost when running x86/x86_64 (VT-capable CPU required)
publicvnc - enable a VNC server open to all hosts
- qemuparams="xyz" - specify custom parameters to QEMU
- bootparams="xyz" - specify custom kernel parameters during boot
+ audio - enable audio
+ tcpserial=<port> - specify tcp serial port number
+ biosdir=<dir> - specify custom bios dir
+ biosfilename=<filename> - specify bios filename
+ qemuparams=<xyz> - specify custom parameters to QEMU
+ bootparams=<xyz> - specify custom kernel parameters during boot
+ help: print this text
