I'm also thinking that we can stop doing the transforms that we do on import that make it harder than it needs to be to continue merging. Slight changes to the build infrastructure, as well as git's vastly better merging abilities should allow us to drop about 2k lines of diffs, allowing us to audit the delta with upstream, which currently is all-in at: 347 files changed, 2891 insertions(+), 1700 deletions(-) which is kinda hard to audit for correctness. The vast majority of the files changed are just hacking headers that's better done with the build system. Once that's fixed we can look at why we have 6 files that have over 100 lines of difference each (much if it has the feel of mismerges rather than intention).
