[PATCH v4 00/45] Massive improvents to rebase and cherry-pick

Hi,

These are improvements to 'git rebase' by using a much improved 'git cherry-pick'. I already sent some of these, but they have been revamped.

These changes require reorganization of the code in order to have a builtin/lib.a library.

A new builtin/rewrite.c helper is added, and builtin/commit updated to use that.

A new git-rebase--cherypick mode is added, and it replaces git-rebase--am and git-rebase--merge.

I also added the new rebase tests by Martin von Zweigbergk to make sure everything works, and in fact, it works better than before, since now all the rebase modes are consistent with each other.

I don't have any hopes of these getting merged, because people have no interest in fixing the ./*.o ./builin/*.o divide problem, only interested in arguing that libgit.a is not a real library, and it should never be. So my obviously cleanup is rejected.
