gitk: Implement multiple views
With this, gitk can know about the graphs for multiple sets of files and directories of interest. Each set of files/dirs and its graph is called a "view". There is always the "All files" view, which is the complete graph showing all commits. If files or dirs are specified on the command line, a "Command line" view is automatically created. Users can create new views and switch between them, and can delete any view except the "All files" view. This required a bit of reengineering. In particular, some more things that were arrays have now become lists. The idrowranges array is still used while the graph is being laid out, but for rows that have been laid out we use the rowrangelist list instead. The cornercrossings and crossings arrays no longer exist, and instead we compute the crossings when needed (in assigncolor). Still to be done: make the back/forward buttons switch views as necessary; make the updatecommits function work right; preserve the selection if possible when the new view has to be read in; fix the case when the user switches away from the current view while we are still reading it in and laying it out; further optimizations.
