Unsquashed version at v2-rc-unsquashed, but that cannot be merged as it breaks bisects at several points. All bugs will not bisect to this humongous change. It all started with a conversion of the Bash scripts to Python, mainly because I couldn't stand not being able to properly use --options for run which has a million options. Then since that required a full testing, I decided to do all the refactorings that I had in mind at once, and so I did and it became v2-rc. This is the largest patch I have ever done! OMG a few weeks of extra time. I'm never writing a Bash script for anything that starts getting big again. Some of the features are: * separate build-qemu and build-gem5 commands * common: convert scripts to python. Add --option for everything * rename build to build-buildroot now that we are splitting all the build commands, Linux kernel to follow * move all git submodules to submodules/ and all buildroot packages to packages/ * refactor the out/ structure. Keep projects on toplevel, because guest projects separate archs and host ones don't, making a toplevel arch wrong * do-release: rename to just release https://stackoverflow.com/questions/16174992/cant-get-argparse-to-read-quoted-string-with-dashes-in-it * run: add --terminal and explain gem5 pdb * just track the lvimrc * store CLI kernel config fragment inside buildlroot to avoid conflicts * gem5: document m5 initparam * readme: make a bunch of things awesomer * readme: fix broken refs * parsec-benchmark: update to 75d55ac446a43c47efb1044844a108c6c330184c Could not fetch otherwise. * gem5: M5_OVERRIDE_PY_SOURCE
