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.
