simplemerge: make `localorother` a "mode" instead of a separate thing

`simplemerge()` takes a `mode` argument, which can be "union", "merge"
or "mergediff", and a `localorother` argument, which can be `None`,
"local", or "other". The two options are not at all orthogonal -- most
combinations don't make sense. Also, at least "union", "local", and
"other" are very closely related. Therefore, it makes sense to combine
them into one.

It probably makes sense to split the `mode` argument into `resolve`
and `marker_style`, where the former can be `None`, "union", "local",
or "other", and the latter can be "merge", "merge3", "mergediff", or
"minimize". This is a good step in that direction whether or not we
end up doing that.
