merge: add mergeresult.mapaction to improve speed
As a part of [hg update] we convert all [ACTION_CREATED] merge
results into [ACTION_GET] actions, and that's slightly inefficient
because every insertion pays the full cost of maintaining the
[mergeresult] data structure up to date.
This commit adds a function [mapaction], which is faster.
(saves around 0.3s on a large update involving ~400k files)
