graphmod: augment the graph to include more information about the edges The walker knows when an edge leads to a direct parent, a grandparent (skipping revisions not part of the revset) and parents that are missing altogether (neither it nor a grandparent is in the revset). Add this information to the parents sequence yielded.

graphmod: refactor state handling Move ASCII graph state to a dictionary, to clarify what is being tracked. Move the 'seen' state (tracking currently active edges) into this structure.

templater: move label() function from color extension ui.label() is no-op by default, so we can just call ui.label() by label() template function no matter if the color is enabled or not.

templater: make label() take unknown symbol as color literal Instead of the mapping hack introduced by b775a2029e8d, this patch changes the way how a label symbol is evaluated. This is still hackish, but should be more predictable in that it doesn't depend on the known color effects. This change is intended to eliminate the reference to color._effects so that color.templatelabel() can be merged with templater.label().
