Debug build

For Arch Linux, you can use the provided PKGBUILD in archpkg to get a debug version of 5.2.18, with the 3D security fixes from July 2018 reverted.

Library

lib/hgcm.py and lib/chromium.py provide high-level access to the HGCM interface and to the VBoxSharedCrOpenGL service, via VBoxGuest IOCTLs. chromium.py can be used to very easily experiment with Chromium from Python inside the guest. I used it to build a very simple, completely dumb fuzzer that found multiple trivial crashes in minutes.
