Paul Mackerras 22626ef4fd gitk: Don't reread git-rev-list output from scratch on view switch ...

Previously, if we switched away from a view before we had finished
reading the git-rev-list output for it and laying out the graph, we
would discard the partially-laid-out graph and reread it from
scratch if we switched back to the view.  With this, we preserve the
state of the partially-laid-out graph in viewdata($view) and restore
it if we switch back.  The pipe to git-rev-list remains open but we
just don't read from it any more until we switch back to that view.

This also makes linesegends a list rather than an array, which turns
out to be slightly faster, as well as being easier to save and restore.

The `update' menu item now kills the git-rev-list process if there is
one still running when we do the update.
