[PATCHv2 0/9] --left/right-only and --cherry-mark

This is a replacement for mg/rev-list-one-side-only in pu. The --left/right-only related commits (1-4/9) are unchanged.

5/9 is new and refactors the generation of commit marks (<>-) which we currently do in 5 places, to ease maintenance and extensibility.

6,7 are new and introduce "--cherry-mark" to the revision walker which marks those commits which "--cherry-pick" would omit.

8,9 are amended as compared to pu, introducing "--cherry" as a shortcut for "--cherry-mark --right-only --no-merges" to produce output much like "git cherry" with the full flexibility of rev-list/log. (We could use the previous version instead, or with a different synonym; or introduce rev-list-option aliases...)

The mark for patch-equivalent commits is '=' because git-cherry's '-' is used for boundary commits already.

The mark for non-equivalent commits is '+' (following git-cherry), or '<'/'>' with --left-right, or '*' with --graph.

This is up for bike-shed^W^Wdiscussing - we could use ' ' instead or even '*' also without --graph, or '+' even with --graph.

I would in fact prefer ' ' without --graph and '*' with --graph, which would make it even more different from git-cherry's output, though. (Personally, I never liked git-cherry's output anyways.)

This is also the base for refactoring git-format-patch and git-cherry, of course, where the latter would be helped if it's ok to change the output format.
