ll-merge: make flag easier to populate ll_merge() takes its options in a flag word, which has a few advantages: - options flags can be cheaply passed around in registers, while an option struct passed by pointer cannot; - callers can easily pass 0 without trouble for no options, while an option struct passed by value would not allow that. The downside is that code to populate and access the flag word can be somewhat opaque. Mitigate that with a few macros.

ll-merge: let caller decide whether to renormalize Add a “renormalize” bit to the ll-merge options word so callers can decide on a case-by-case basis whether the merge is likely to have overlapped with a change in smudge/clean rules. This reveals a few commands that have not been taking that situation into account, though it does not fix them. No functional change intended.

ll_merge(): add ancestor label parameter for diff3-style output Commands using the ll_merge() function will present conflict hunks imitating ‘diff3 -m’ output if the merge.conflictstyle configuration option is set appropriately. Unlike ‘diff3 -m’, the output does not include a label for the merge base on the ||||||| line of the output, and some tools misparse the conflict hunks without that. Add a new ancestor_label parameter to ll_merge() to give callers the power to rectify this situation. If ancestor_label is NULL, the output format is unchanged. All callers pass NULL for now.
