[PATCH/WIP 0/8] Convert git-rebase.sh to C

In the spirit of sharing code proactively [1], despite my embarrassment, this is what I got for converting git-rebase.sh to C. Note that this is only about git-rebase.sh, not git-rebase--*.sh. Some changes in git-rebase.sh are pushed back to git-rebase--*.sh. The idea is we convert git-rebase.sh first, then the rest later.

Anybody who wants to base their work on this code, feel free to --reset-author (and take all the bugs with you, I'm sure there are lots of them). This work is from 2013. git-rebase.sh has received lots of updates since then, so there's still lots of work to do.
