This is equivalent to a diff from 82b42943 to bcd3e80f

Refactor the diff logic for improved modularity and performance. This check-in transitions the diff improvement efforts from a branch to trunk. The effort is not yet complete, but it is stable enough to continue going on trunk. User-visible changes include (1) improved diff display, especially for unified diffs, (2) the new "fossil xdiff" command (promoting the older "test-diff" command into a supported command), and improved performance. Behind the scenes, (3) the class names DOM module used for for HTML diffs is simplified - which may break custom skins, (4) the internal processing of diffs is simplified in many ways. ...
