add merge.renamelimit config option
The point of rename limiting is to bound the amount of time we spend figuring out inexact renames. Currently we use a single value, diff.renamelimit, for all situations. However, it is probably the case that a user is willing to spend more time finding renames during a merge than they are while looking at git-log. This patch provides a way of setting those values separately (though for backwards compatibility, merge still falls back on the diff renamelimit).
