Implement ours/theirs content conflict resolution
Git has different conflict resolution strategies: * There is a tree merge strategy "ours" which just ignores any changes from theirs ("-s ours"). JGit also has the mirror strategy "theirs" ignoring any changes from "ours". (This doesn't exist in C git.) Adapt StashApplyCommand and CherrypickCommand to be able to use those tree merge strategies. * For the resolve/recursive tree merge strategies, there are content conflict resolution strategies "ours" and "theirs", which resolve any conflict hunks by taking the "ours" or "theirs" hunk. In C git those correspond to "-Xours" or -Xtheirs". Implement that in MergeAlgorithm, and add API to set and pass through such a strategy for resolving content conflicts. * The "ours/theirs" content conflict resolution strategies also apply for binary files. Handle these cases in ResolveMerger. Note that the content conflict resolution strategies ("-X ours/theirs") do _not_ apply to modify/delete or delete/modify conflicts. Such conflicts are always reported as conflicts by C git. They do apply, however, if one side completely clears a file's content.
