The patch differs quite a bit from the original jdk8u backport of this change, mainly in the parts that only really serve to interact with Oracle custom build logic, and likely aren't used by anyone in jdk8u main. For example, I chose to keep the existing .hgtip files instead of trying to rename them to something else (.gittip or .src-rev), as updating the external dependencies we have on these file names would be too much work for this release.
