annotate: do not construct attr.s object per line while computing history
Unfortunately, good abstraction has a cost. It's way slower to construct
an annotateline() object than creating a plain tuple or a list. This patch
changes the internal data structure from row-based to columnar, so the
decorate() function can be instant (i.e. no Python in hot loop.)
For code readability, the outermost tuple is switched to an attr.s object
instead.
(original, row-based attr.s)
