[PATCH 0/8] runqemu: refactor it and remove machine knowledge

[Robert Yang <liezhi.yang@windriver.com>]

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.py.
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
* Most of the TUN_ARCH knowledge are gone except aarch64 and powerpc,
  it's not easy to remove the two, so leave them there atm
* 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.py
* Fixed audio support, not limited on x86 or x86_64
* The kvm support is not limited on x86 or x86_64
* Fix SLIRP mode
* 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.

* Tested the following machines, all of them work well:
  genericx86 genericx86-64
  qemuarm qemuarm64
  qemumips qemumips64 qemuppc
  qemux86 qemux86-64
  qemuzynq qemuzynqmp

And also test "bitbake core-image-sato -ctestimage" which uses runqemu, it
also works.
