log: move miscellaneous filter/matcher options to walkopts

Maybe this is the most uninteresting patch. I want to remove the dependency
on untyped/unlabeled opts dict at all.

I thought --no-merges and --only-merges could be merged into a single enum
value, but actually they both can be set to filter out everything.
