revert: Introduce --reset to remove sequencer state To explicitly remove the sequencer state for a fresh cherry-pick or revert invocation, introduce a new subcommand called "--reset" to remove the sequencer state. Take the opportunity to publicly expose the sequencer paths, and a generic function called "remove_sequencer_state" that various git programs can use to remove the sequencer state in a uniform manner; "git reset" uses it later in this series. Introducing this public API is also in line with our long-term goal of eventually factoring out functions from revert.c into a generic commit sequencer.

git-cherry-pick: add allow-empty option git cherry-pick fails when picking a non-ff commit that is empty. The advice given with the failure is that a git-commit --allow-empty should be issued to explicitly add the empty commit during the cherry pick. This option allows a user to specify before hand that they want to keep the empty commit. This eliminates the need to issue both a cherry pick and a commit operation.

cherry-pick: add --allow-empty-message option Scripts such as "git rebase -i" cannot currently cherry-pick commits which have an empty commit message, as git cherry-pick calls git commit without the --allow-empty-message option.

git-cherry-pick: Add keep-redundant-commits option The git-cherry-pick --allow-empty command by default only preserves empty commits that were originally empty, i.e only those commits for which <commit>^{tree} and <commit>^^{tree} are equal. By default commits which are non-empty, but were made empty by the inclusion of a prior commit on the current history are filtered out. This option allows us to override that behavior and include redundant commits as empty commits in the change history. Note that this patch changes the default behavior of git cherry-pick slightly. Prior to this patch all commits in a cherry-pick sequence were applied and git commit was run. The implication here was that, if a commit was redundant, and the commit did not trigger the fast forward logic, the git commit operation, and therefore the git cherry-pick operation would fail, displaying the cherry pick advice (i.e. run git commit --allow-empty). With this patch however, such redundant commits are automatically skipped without stopping, unless --keep-redundant-commits is specified, in which case, they are automatically applied as empty commits.

rebase -i: generate the script via rebase--helper The first step of an interactive rebase is to generate the so-called "todo script", to be stored in the state directory as "git-rebase-todo" and to be edited by the user. Originally, we adjusted the output of `git log <options>` using a simple sed script. Over the course of the years, the code became more complicated. We now use shell scripting to edit the output of `git log` conditionally, depending whether to keep "empty" commits (i.e. commits that do not change any files). On platforms where shell scripting is not native, this can be a serious drag. And it opens the door for incompatibilities between platforms when it comes to shell scripting or to Unix-y commands. Let's just re-implement the todo script generation in plain C, using the revision machinery directly. This is substantially faster, improving the speed relative to the shell script version of the interactive rebase from 2x to 3x on Windows. Note that the rearrange_squash() function in git-rebase--interactive relied on the fact that we set the "format" variable to the config setting rebase.instructionFormat. Relying on a side effect like this is no good, hence we explicitly perform that assignment (possibly again) in rearrange_squash().

The reimplemented logic also happens to fix a bug where commented-out lines (representing empty patches) were dropped by the previous code. While at it, clarify how the fixup/squash feature works in `git rebase -i`'s man page.
